CDC official: No clear evidence Wuhan coronavirus can spread before people show symptoms

A woman checks her son's forehead on January 27, 2020 in Wuhan, China. The city remains on lockdown for a fourth day.

There is not yet “any clear evidence” that people can transmit the Wuhan coronavirus before they begin exhibiting symptoms, Dr. Nancy Messonnier, director of the US Center for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases, told reporters on Monday.

But, she said, it’s a possibility health officials are investigating.

Messonnier’s comment comes after China’s health minister Ma Xiaowei said people can spread the virus before they become symptomatic, but offered no explanation as to why he believes that to be the case.

The CDC has based early theories about the novel virus on what we know about SARS and MERS, which are part of the same family of viruses. Based on that knowledge, the CDC also believes that symptoms of the Wuhan coronavirus may take anywhere from two days to two weeks after exposure to show symptoms. It is also thought to transmit chiefly through droplets from coughs or sneezes, consistent with comments made Monday by Chinese officials.

On the call with reporters, Messonnier also seemed to allay concerns that the virus could be transmitted via packages sent from China. Coronaviruses like SARS and MERS tend to have poor survivability, and there’s “very low, if any risk” that a product shipped at ambient temperatures over a period of days or weeks could spread such a virus.

“We don’t know for sure if this virus will behave exactly the same way,” Messonnier said, but there’s no evidence to support transmission of the virus via imported goods.

Messonnier repeated her message that the immediate risk to the US public is low at this point.

UK government asks Britons who returned from Wuhan in past 14 days to 'self-isolate'

He said British authorities were looking to contact the 1,460 people who have landed in the UK from Hubei province. 

Hancock said that the risk to the UK population was low, but added that in the event of cases arising in the country the UK was “prepared and well equipped.” He said the UK was working with the WHO and the international community.

Hancock added:

He added that those individuals should not leave home until they have been advised by a clinician. 

There are 19 people under investigation for coronavirus in Ontario

Ontario’s Chief Medical Officer of Health Dr. David Williams said there were 19 people under investigation for coronavirus in the province at the moment.

What that means: Dr. Williams said that for a person to be “under investigation,” they must have both signs or symptoms of a respiratory condition and a travel history that is “of importance, which is to Wuhan or around the district of the Hubei province.”

He added that people being investigated for coronavirus will undergo a battery of health tests to rule out other causes. 

CDC publishes more information on suspect cases

The CDC site includes a map of known cases in the US.

The US Centers for Disease Control has published a page detailing the number of people who are under investigation for the novel coronavirus in the US.

The site gives the number of people in the US who have been under investigation, the number of confirmed positive cases, the number of negatives and the number still pending, as well as the number of states where people are under investigation.

It states that of the overall People Under Investigation (PUI) in the United States, 5 have tested positive, 32 tested negative and the results of 73 others are pending.

Information regarding the number of PUIs will be updated on Mondays, Wednesdays and Fridays, the site says.

CDC expands travel advisories for China to include the entire province that includes the city of Wuhan

The US Centers for Disease Control and Prevention has expanded its travel notifications for China — broadening its highest level, “Level 3 - Warning,” to include all of Hubei province, not just the city of Wuhan.

Why the new virus doesn't have a name yet

Masked patients walk out of the No. 3 Hospital in Yichang city in central China's Hubei province on Thursday, January 23.

News about the coronavirus has dominated the headlines for days, as it has killed at least 80 people in China and spread across the globe.

Yet it still doesn’t have an official name.

Although it has been widely referred to as the “Wuhan coronavirus,” the virus is still formally known as “novel coronavirus” or “2019-nCoV,” where the “n” stands for “novel”, while the “CoV” denotes “coronavirus.”

In the past, some viruses been named after the place or a region where they were first identified – that was the case with MERS, which stands for Middle East respiratory syndrome, in 2012. Ebola virus was named after a river in the Democratic Republic of the Congo. Lyme disease is named after a town in Connecticut.

However, in 2015, the WHO issued new guidance, urging scientists to avoid names that could cause unnecessary negative effects on nations, economies and people. It said:

The WHO said that a disease name should consist of generic descriptive terms, based on the symptoms, those who it affects, its severity or seasonality.

Shanghai businesses and schools will remain shut long into February in attempts to contain virus

Visitors stand outside a closed temple in Shanghai, China, on Saturday, January 25.

Shanghai’s government has ruled that all businesses in the city should remain shut until February 9, as it announced a series of new measures against the spread of the coronavirus.

Other moves include suspending schools until February 17, and implementing strengthened quarantine inspections for workers returning to Shanghai.

Only businesses the government deems vital to the operation of China’s biggest city – such as gas stations, pharmacies and supermarkets – will be allowed to remain open, the municipal government said in a statement Monday.

It added that schools will be re-opened after an assessment on the epidemic.

This comes as the number of confirmed coronavirus cases in Shanghai increased to 53, including one death.

Are people infectious before they appear ill? Experts weigh in

In this 2015 file photo, Dr. Yvonne Doyle speaks at City Hall in London.

Chinese health officials said Sunday that the coronavirus can be spread before any symptoms appear, meaning carriers may not realize they are infected before they transmit the virus to others.

There’s still lots we don’t know about this outbreak, however, and according to Dr. Yvonne Doyle, medical director of Public Health England, “it isn’t confirmed that people are infectious before they appear to be ill.”

“That’s one of the things we have to learn,” she added.

Here’s an excerpt (lightly edited for clarity) of Dr. Doyle’s interview with BBC Radio 4’s Today Program on Monday:

Q: (We’re) hearing from China that people can spread the virus without having any symptoms…

A: At the moment we don’t have confirmed evidence that that’s the case. It’s reasonable of course to assume that could happen, but at the moment we don’t know that, because this is a novel virus.

Q: Do you think it is likely that we are going to see cases (in the UK)?

A: Yes I do… I think I would be surprised if there wasn’t. We are well prepared since we spotted this in the early new year. We have been working with increasing intensity with the NHS (National Health Service) to make sure we are well prepared, and we are. 

Q: (We’re) also hearing Chinese officials are also developing a vaccine, will that be ready in time?

A: It won’t be ready in time at the moment. Vaccines take months, maybe years to develop. 

A quick reminder: What is the Wuhan coronavirus?

Health experts are trying to understand how the coronavirus is being transmitted, who is at most risk and whether transmission is occurring mostly in hospitals or in the community.

This is what we know about the illness so far:

Coronavirus is a large family of viruses, which include severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).

Common symptoms include: a runny nose, cough, sore throat, and possibly a headache. Those who have a weakened immune system, particularly the young and the elderly, are at risk of the virus turning into a more serious respiratory tract illness.

Authorities said the Wuhan coronavirus was passed from animals to humans; can be spread from person to person; and appears to cause pneumonia in people who have weakened immune systems.

It is thought to be milder that SARS and MERS and take longer to develop symptoms. Patients to date have typically experienced a mild cough for a week followed by shortness of breath, causing them to visit a hospital.

The number of cases of a deadly new coronavirus rose to nearly 300 in mainland China Tuesday as health officials stepped up efforts to contain the spread of the pneumonia-like disease which medicals experts confirmed can be passed from human to human. The number of those who have died from the virus in China climbed to six on Tuesday and cases have been reported in other parts of Asia including in Thailand, Japan, Taiwan and South Korea.

Wuhan mayor admits government didn't disclose information in "timely fashion"

The mayor of Wuhan has admitted people were “not satisfied” with the rate that his government released information on the coronavirus, adding that it was “not disclosed in a timely fashion.”

Mayor Zhou Xianwang, whose city is at the epicenter of the virus outbreak, told state-run CCTV Monday that “we didn’t effectively use that information” in its response.

He explained that under Chinese law on infectious diseases, the local government first needs to report the outbreak to the national health department, and then get approval from State Council before they can make an announcement.

The mayor added that he took responsibility for the “unprecedented” decision to lock down the city.

France and Spain to bring hundreds of citizens home from Wuhan

Agnès Buzyn arrives for a meeting with other ministers regarding the first cases of coronavirus infection in France on January 26.

Both Paris and Madrid are working with Chinese authorities to repatriate French and Spanish citizens who are currently in Wuhan.

France will fly its citizens back home from Wuhan “in the middle of next week,” the country’s Health Minister, Agnès Buzyn, said Sunday.

“The Prime Minister has decided to respond to the French people of Wuhan and their request to return. Our consulate team is in contact with the nationals. All those who wish to return will be able to do so,” Buzyn added.  

“We are arranging a direct flight from Wuhan,” she said.

Buzyn said those who return to France will be monitored in one place for 14 days to avoid any spread of the virus.

A spokesman for the Spanish Foreign Ministry also told CNN that “the ministry is working with other European Countries affected to organize a joint repatriation flight.”

In a statement, the ministry said: “The Minister of Foreign Affairs, EU and Cooperation has spoken with the Consul General of Spain in Beijing to obtain information of the situation of Spaniards in Wuhan.”

There are about 20 Spanish people in Wuhan, the ministry said.

People need to be prepared for this to become a global epidemic: Hong Kong expert

Gabriel Leung, chair professor of public health medicine at the Faculty of Medicine at the University of Hong Kong,

The number of people infected by the Wuhan coronavirus could potentially double every six days in the absence of a major intervention by public health authorities, according to Professor Gabriel Leung, chair of public health medicine at University of Hong Kong (HKU).

Leung, who is also the founding director of the World Health Organization Collaborating Center for Infection Disease Epidemiology and Control in Hong Kong, gave his forecast on the likely extent of the outbreak during a press conference held at HKU on Monday afternoon.

He said he had submitted his report to Beijing and Hong Kong authorities as well as to the World Health Organization (WHO). 

Leung said according to his team’s model, the number of cases of Wuhan coronavirus including patients that are incubating (not showing symptoms) could approach 44,000 cases as of January 25. 

The results of two scenarios – one with a population quarantine as has been seen in Wuhan and one without – were almost identical, suggesting “population quarantine may not be able to substantially change the course of the epidemic in the other major city clusters.”

In addition to Wuhan, Leung warned China could see epicenters of self-sustaining epidemics in other major cities in the mainland, including in Beijing, Shanghai, Guangzhou and Shenzhen.

“It is not a prediction, it is not certain, but these finding makes us concerned enough to alert the authorities and to alert the public,” Leung said.

According to Leung’s forecast, the number of cases could peak between mid-May and mid-April in major cities. 

In order to prevent this from happening, there would need to be “substantial draconian measures limiting population mobility sooner rather than later,” said Leung.

Leung said people need to be prepared for the outbreak to become a global epidemic, though it is “not a certainty by any stretch of the imagination…we must prepare better for it.”

Get caught up: here's the latest on the outbreak

There are more than 2,700 confirmed cases of the coronavirus and 80 deaths in China. Worldwide concern is mounting about the rate of its spread. 

Here’s what you need to know:

  • Outbreak in China: 2,744 cases have been confirmed in mainland China, and 80 people are dead. There are full or partial lockdowns in 15 Chinese cities in an effort to limit the virus’s spread.
  • Global spread: There are more than 50 cases confirmed around the world, in the United States, Malaysia, Singapore, Thailand, France, Australia, and more. Some countries are trying to evacuate their citizens out of Wuhan, the city at the epicenter of the outbreak.
  • Contagious before symptoms: People can spread the virus before symptoms show, China warned on Sunday – meaning people may have been spreading the virus without knowing they were ill.
  • Transmission: The major transmission mode of the coronavirus is through “close range droplet transmission,” Feng Luzhao, researcher from the Chinese Disease Prevention and Control Center, said. His comments suggest that most people have contracted the virus by being in close contact with an infected person.
  • Stretched hospitals: A nurse from the Central Hospital of Wuhan tells CNN at least a dozen medical staff from the facility are infected with the Wuhan coronavirus. Videos and witness accounts in Wuhan show packed hospitals and overworked staff. About 1,600 medical professionals are being sent to the city on Sunday and Monday.

Here's a breakdown of where the coronavirus has spread through China

CDC and LAX assisting in LA coronavirus contact tracing

Passengers wear protective masks to protect against the spread of the coronavirus as they arrive at the Los Angeles International Airport  on January 22.

After a person in Los Angeles County tested positive for the Wuhan coronavirus, efforts are being ramped up to trace everyone the patient came into contact with.

The US Centers for Disease Control and Prevention (CDC) and Los Angeles International Airport are assisting in contact tracing, along with the Los Angeles County Department of Public Health.

Contact tracing is defined as the identification and follow-up of people who may have come into contact with an infected person, according to the World Health Organization.

Ferrer said the patient, who is a resident of Wuhan, ground zero for the outbreak, had previously transited through LAX.

The individual presented themselves to health care authorities on January 22, saying they were ill. They were assessed by health care authorities and brought to a hospital in Los Angeles, where the patient remains.

The health department provided no further details about the patient’s condition, gender or age, or how many people have been contacted through their investigation.

The agency also announced at the press conference that all travelers coming from China through LAX are currently being screened.

The Los Angeles patient is one of two confirmed cases of Wuhan coronavirus in California. The other is in Orange County. The CDC on Sunday afternoon updated the total number of confirmed coronavirus cases in the United States to five.

A holiday village in Hong Kong has become a coronavirus quarantine camp

An aerial view shows the Lady MacLehose Holiday Village in Hong Kong.

Set within a protected area of the picturesque Sai Kung Country Park, the 13.2-hectare Lady MacLehose Holiday Village is known for its greenery and tranquility.

Since the early 1980s Hong Kongers have come to the holiday village to get away from the bustling city and enjoy its camping facilities and outdoor activities.

But since January 23, the holiday camp has been turned into a quarantine center to house those who have came into close contact with confirmed cases of coronavirus in Hong Kong.

A check-point has been set up at the entrance of the village and police monitor those going in and out.

According to the Leisure and Cultural Services Department, the Lady MacLehose Holiday Village can accommodate 268 residential campers and has 52 standalone bungalows.

The Hong Kong government has also turned the Lei Yue Mun Park and Holiday Village on Hong Kong island into a quarantine center and plans to do the same with a third facility.

“To cope with the quarantine need in future, the DH (Department of Health) is contacting holiday villages under other non-governmental organizations as potential sites of quarantine centers,” a government statement said Sunday.

However, there were protests in the northern Hong Kong town of Fanling – near the Chinese border – after it was announced that an unoccupied apartment building there would be converted to a “temporary” quarantine center. Residents set up roadblocks and clashed with police, and on Sunday the authorities said they were abandoning the plan.

Hong Kong authorities said residents of Hubei, the province of which Wuhan is the capital, and people who have visited the region in the last 14 days, will not be able to enter the city. The order does not cover Hong Kong residents, though they may be placed under quarantine.

Hong Kong has eight confirmed cases of the Wuhan coronavirus.

Each confirmed patient infects 2 to 3 people, say British scientists

A medical staff member takes the temperature of a man at the Wuhan Red Cross Hospital on January 25.

Scientists at Imperial College London have estimated that each person infected with the Wuhan coronavirus has gone on to infect two to three people, according to a report released Saturday.

“We estimate that, on average, each case infected 2.6 (uncertainty range: 1.5-3.5) other people up to January 18, 2020, based on an analysis combining our past estimates of the size of the outbreak in Wuhan with computational modeling of potential epidemic trajectories,” said the report.

“This implies that control measures need to block well over 60% of transmission to be effective in controlling the outbreak,” it added.

When it comes to outbreaks, scientists and public health experts are concerned with how quickly a disease can spread and its mortality rate.

But there is still a lot more to learn about the virus, and scientists have warned against alarmism.

“It is quite easy to get fixed on a particular number but such predicted numbers will vary considerably at this early stage in an epidemic,” Mike Turner, Director of Science, The Wellcome Trust, said in a statement.

“This makes it more difficult to put in place effective control measures. A lot of people are working furiously to try and control this epidemic.”

On Sunday, Chinese officials said people can spread the virus before they have symptoms.

China's unprecedented reaction to the Wuhan virus probably couldn't be pulled off in any other country

A police officer stands guard outside of Huanan Seafood Wholesale market where the coronavirus was detected in Wuhan.

As the world watches the developing crisis around the deadly Wuhan coronavirus, it’s difficult to know how worried to be. One thing is clear, however: China is treating the matter extremely seriously.

Almost 60 million on lockdown: With the number of confirmed cases in the country approaching three thousand, and at least 80 deaths, China has placed almost 60 million people on lockdown, with full or partial travel restrictions on 15 cities across Hubei, the central Chinese province of which Wuhan is the capital.

Never been done in China before: The unprecedented scale of the response speaks in part to the sheer size of China – 60 million people is greater than the entire population of South Korea, and Hubei spans the equivalent area as Syria. Such a lockdown has never been carried out in China before, not even during the 2003 SARS outbreak. The cost of it is staggering, not just in terms of manpower or funds, but also the economic hit Hubei will take and the knock on effect this will have on the wider Chinese economy during a sensitive period.

Powerful leadership: That China is able to pull something like this off is thanks to the ability of a centralized, powerful leadership to react in a crisis. It’s also a sign of just how vital it is for that leadership not to screw up

Writing on Sunday, analysts Adam Ni and Yun Jiang said that the Chinese Communist Party’s “prestige and legitimacy are both on the line” in how they handle the crisis.

US evacuation flight out of Wuhan may no longer head to San Francisco

A United States government-chartered plane is set to evacuate about three dozen US diplomats and their families from Wuhan, the epicenter of the coronavirus, on Tuesday.

But the plane may not fly to San Francisco as previously announced by the State Department, a US official with knowledge to the matter told CNN.

The flight, operated by a private charter company using a Boeing 767 with 240 seats, will land somewhere in California, the official said.

It’s unclear how many non-diplomat US citizens will be aboard the flight, which will be staffed with medical personnel.

The US consulate in Wuhan, which is now closed, reached out to Americans who had registered with them and offered seats on the plane. Non-diplomat US citizens will be billed for the flight, the official said.

The city is normally a transport hub for central China, but Chinese authorities have placed Wuhan under a travel lockdown, barring all departures from the city’s airport and rail stations.

A Chinese foreign ministry spokeswoman said on Sunday that after the US proposed to evacuate its citizens from the city, Beijing made arrangements, “that are consistent with our epidemic control measures” and provided “necessary assistance and convenience.”

Other nations, such as Australia and India, are working on ways to repatriate their citizens from Wuhan.

Here's a rundown of all the coronavirus cases in mainland China

There are more than 2,700 confirmed cases of the coronavirus and 80 deaths in China.

Across China, 15 cities with a combined population of over 57 million people have been placed under full or partial lockdown.

Worldwide concern is mounting about the rate of transmission, with Chinese health officials saying the virus can be spread before any symptoms appear.

Here’s a rundown of how many cases are in each Chinese province:

  • Hubei (includes Wuhan): 1,423, including 76 deaths
  • Guangdong: 146

How the Wuhan coronavirus affects the body

Mongolia shuts schools as it goes on high alert for coronavirus

Mongolia will close its schools from January 27 until March 2 as a preventative measure against the Wuhan coronavirus, state news agency Montsame reported

There are no reported cases in Mongolia, but the country is considered to be at high risk of the virus spreading there as it borders China, where the coronavirus originated.

Mongolian officials are on high alert in case the virus spreads.

The Chinese autonomous region of Inner Mongolia, which runs along Mongolia’s southern border, reported its first confirmed case of coronavirus last week.

There are now confirmed cases in every Chinese province, except the remote autonomous region of Tibet.

The ruling in Mongolia followed a cabinet meeting on Sunday to discuss preventative safety measures. 

The cabinet also ordered public gatherings be cancelled and that border crossings for “auto vehicles and pedestrian traffic” be cancelled starting Monday.

The agency also reports that 31 Mongolia students in Wuhan will be repatriated on Monday.

Australia confirms fifth case of coronavirus

Five people in Australia have now been confirmed to have the Wuhan coronavirus, the Department of Health said in a statement Monday.

The latest patient to be infected with the respiratory virus in the country is a 21-year-old woman who flew into Sydney on the last flight from Wuhan last week, CNN affiliate Nine News reports.

The deadly virus was first identified in Hubei province’s Wuhan in December and since then it has infected at least 2,700 people and killed 80 in mainland China.

The woman in Australia developed symptoms 24 hours after arriving back into Sydney on Thursday, health officials said. When they worsened, she went to the emergency department.

“We were alerted the testing was done, the patient was immediately put into isolation in a home isolation setting, and then once the diagnosis was confirmed, the patient has just been transported to Westmead Hospital,” New South Wales Chief Health Officer, Dr. Kerry Chant said, according to Nine News.

On Monday, Australia’s Health Minister said the country was working on ways to repatriate its citizens from Wuhan, including 100 “young Australians.”

Video game company urges players to avoid Plague Inc. game for information on coronavirus

Plague Inc. players can watch as their disease spreads from country to country.

The popularity of a video game that teaches players about how diseases spread has grown sharply amid concerns about the spread of coronavirus. Now, the company is warning people to seek information on the disease from official sources, rather than relying on its game, Plague Inc. 

The company said it often sees a surge in new users amid new disease outbreaks, as people try to better understand how diseases operate and spread. 

Plague Inc. is an app and online video game developed by Ndemic Creations where players become a disease and aim to infect the world by developing new means of transmission and symptoms — countering countries closing their borders, news reports about the disease and scientists trying to develop cures.

The company said in its statement that the game was designed to be “realistic and informative, while not sensationalizing serious real-world issues.” However, it pointed out that the game is not a “scientific model” and should not be relied upon for information about coronavirus.

Shanghai manufacturer of coronavirus test kits says it has enough supplies

A Shanghai manufacturer says it is fully equipped to ensure sufficient supply of Wuhan coronavirus test kits to meet nationwide demand, according to state media CCTV.

The factory, belonging to Shanghai ZJ Bio Tech, is capable of producing 8,000 boxes per day and has raw materials in stock to make tests kits for two million people, CCTV reports.

Chinese state media is also reporting that there are more than 1,000 hospitals nationwide that have laboratories capable of preforming tests to identify the Wuhan coronavirus.

Nurse from Wuhan hospital tells CNN at least a dozen medical staff infected with virus

Medical staff members wear protective suits at the Zhongnan hospital in Wuhan.

A nurse from the Central Hospital of Wuhan tells CNN at least a dozen medical staff from the facility are infected with the Wuhan coronavirus.

“Some are being given emergency treatment. Those who have milder symptoms have been sent home with medication,” the nurse, who spoke on the condition of anonymity told CNN Sunday.

The nurse said she has also contracted the virus and that her symptoms were relatively mild. She was discharged and told to isolate herself while recuperating at home. The nurse said she is more than happy to be out of the hospital where she believes the virus is endemic.  

“The concentration of the virus in the hospital is so great,” the nurse said via the Chinese instant messaging app WeChat.

Her account comes as Beijing said it would deploy another 1,600 medical professionals to Wuhan to help the city cope with the growing number of coronavirus patients, Chinese Health Minister Ma Xiaowei said in a rare Sunday news conference. 

Another 1,000 workers are on standby, Ma said.

Authorities acknowledged that Wuhan, a city 11 million people and ground zero of the outbreak, and much of Hubei province are facing manpower and medical supply shortages. 

Healthcare workers in Wuhan, including four who spoke to CNN on the phone, have complained of being overstretched and lacking resources to combat the crisis. 

“In terms of resources, the whole of Wuhan is lacking,” one Wuhan-based healthcare worker told CNN by phone. The person said they were looking for more protective clothing, protective goggles and masks.  

At the news conference Sunday, Wang Jiangping, the vice minister of of industry and information technology, said Hubei needs about 100,000 protective medical suits per day – but the 40 factories across the country making them only produce 30,000 daily.

Wang said authorities are now trying to get factories to resume production – most would have closed for the Lunar New Year holiday – and requisition factories that make the suits for export.

Dow futures tumble on fifth US case of coronavirus

US stock futures dropped sharply Sunday night as fears of the coronavirus grew.

Dow futures fell by as much as 300 points, and were last down about 200 points. S&P 500 (INX) futures were down about 0.8% and Nasdaq futures were lower by about 1.1%.

In Tokyo, the Nikkei 225 was last down 1.7%. It is the only major stock market in Asia open Monday due to the Lunar New Year.

The Dow closed down 0.6% on Friday —its worst day of the year. Also Friday, the S&P 500 had its worst day since early October, while the Nasdaq had its lowest close since early December.

Most Wuhan coronavirus transmissions from “close range droplet transmission." Here's how to protect yourself

Chinese women and a child all wear protective masks as they walk under decorations in a Beijing park.

The major transmission mode of the Wuhan coronavirus is through “close range droplet transmission,” Feng Luzhao, researcher from the Chinese Disease Prevention and Control Center, said at Monday’s press conference by the National Health Commission.

His comments suggest that most people have contracted the virus by being in close contact with an infected person.

Droplet transmission is when a virus is passed on due to an infected person sneezing or coughing, and another comes into contact with those infected particles.

Feng said that, “people should avoid going out, especially going to crowded areas.”  

According to a how-to guide published by Chinese Disease Prevention and Control Center, the public is advised to reduce visiting families during Lunar New Year, stay home and rest, and avoid going to crowded public areas, especially those with less air flow such as theaters, internet cafes, KTV (karaoke), and shopping centers.

With more cases of the Wuhan coronavirus confirmed outside mainland China, here’s how can you minimize your risk of getting infected.

Avoid close contact with anyone showing symptoms of respiratory illness, such as coughing and sneezing, the World Health Organization says. Other symptoms of this coronavirus include fever and shortness of breath. Severe cases can lead to pneumonia, kidney failure and even death.

Cook food thoroughly: Scientists believe this coronavirus started in another animal and then spread to humans. So health officials recommend cooking meat and eggs thoroughly.

Avoid live animal markets: Anyone with underlying medical conditions should avoid live animal markets and raw meats altogether, since those people are “considered at higher risk of severe disease,” the World Health Organization says.

Wash hands: Wash your hands often with soap and water for at least 20 seconds.

Cover mouth and nose: If you’re the one feeling sick, cover your mouth and nose when you cough or sneeze, and disinfect the objects and surfaces you touch.

Wear a mask: If you or your doctor suspect you might have the Wuhan coronavirus, the CDC advises wearing a surgical mask.

Common sense: In general, the public should do “what you do every cold and flu season,” said Dr. John Wiesman, the health secretary in Washington state – where the first US case of Wuhan coronavirus was confirmed.

Chinese officials call for those who were in Wuhan to self-quarantine and report to "community leaders"

Chinese officials have called on anyone who was in Wuhan in the last 14 days to self-quarantine and report to community leaders in order to prevent the spread of the coronavirus, according to an expert speaking at the Chinese National Health Commission press conference on Monday.

There are no official figures on the number of people who have visited, or passed through the city since the outbreak was first identified in mid-December.

However, the number is likely to be large. Wuhan, which is home to an estimated 11 million people, is one of China’s most important cities.

Located on the confluence of the Yangtze River and its largest tributary, the Han River, it is considered the political and economic capital of central China.

It’s also a major travel hub.

In addition to conventional railway networks, Wuhan is one of the stops on two of the main long-haul high-speed railway lines: Beijing-Guangzhou (from north to south) and Shanghai-Chengdu high-speed railway (from east to west).

It’s also home to one of just four major train maintenance centers in the country.

The city’s international airport is the only airport in the mid-China region to have direct flights to five different continents.

According to data from aviation website Flightconnections.com, Wuhan Airport services non-stop scheduled passenger flights to 109 destinations in 20 countries. These include major cities like London, Moscow, Paris, Rome, New York, San Francisco, Bangkok, Tokyo and Seoul.

The airport’s passenger throughput in 2018 exceeded 24 million and was expected to hit 29 million in 2019.

Singapore students and teachers must stay away from schools for 2 weeks after returning from mainland China

 Visitors wearing masks arrive at the departure hall of Changi Airport in Singapore.

Singapore has announced that all students and teachers returning from mainland China will be required to self-quarantine for 14 days.

The Ministry of Education said Monday that it will implement the two week leave of absence for all students and staff upon their arrival back in Singapore.

Any student who is on a leave of absence, “will be supported via a home-based learning plan,” the ministry added.

Singapore has urged travelers to defer non-essential travel to mainland China, after the Ministry of Health confirmed four cases of the coronavirus on Saturday.

The Wuhan coronavirus – part of a family of viruses that are common among animals and can cause fever as well as respiratory symptoms when transmitted to humans – has been found in cities all over China, and travelers have since spread the virus to 13 places outside of mainland China, including the US, France, Japan, South Korea, Vietnam, as well as Taiwan, Hong Kong and Macau.

100 "young Australians" could be repatriated from Wuhan

Australia is working on ways to repatriate its citizens from the city of Wuhan, including 100 “young Australians,” Australia’s Health Minister Greg Hunt told national broadcaster ABC Radio Monday.

Hunt said he was in touch with the Chinese Foreign Minister as well as other countries on what can be done for its citizens in Wuhan. 

Hunt also said he expects to get a final results on a fifth suspected cases of the Wuhan coronavirus later Monday.

The Chinese city of Wuhan has become ground zero for the new deadly strain of coronavirus, which has since spread to 13 places outside of mainland China.

Other countries, such as the United States, are also looking to evacuate their citizens from the city, which has been placed under a lockdown.

The US government is arranging a charter flight to evacuate American diplomats and citizens from Wuhan, a US official with knowledge of the matter told CNN Saturday.

Chinese government's response hints at severity of crisis

Chinese President Xi Jinping has ordered officials to take more rigorous measures to prevent the coronavirus from spreading.

The severity of the emerging coronavirus crisis is evident in the Chinese government’s response.

The Standing Committee of the Chinese Communist Party – the country’s top political body, headed by President Xi Jinping – has taken direct control of operations. 

Chinese Premier Li Keqiang arrived in Wuhan Monday to tour local hospitals, according to state media.

And more than 11 billion yuan ($1.58 billion) in government funds have been dedicated to the crisis.

Over the weekend, Xi chaired a meeting with top officials of the ruling Communist Party on the prevention and control of the outbreak.

He pointed out that in facing the grave situation of the accelerating spreading epidemic, it is necessary to strengthen the centralized leadership of the Party Central Committee.

He also demanded that the government at all levels put people’s life and health as the top priority.

“Life is of paramount importance. When an epidemic breaks out, a command is issued. It is our responsibility to prevent and control it,” Xi said.

CDC official: We’re "preparing as if this is a pandemic"

Dr. Nancy Messonnier, director of the US Centers for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases, responded to a statement Sunday by the Chinese health minister Ma Xiaowei that people are infectious before they have symptoms of Wuhan coronavirus.

“We at CDC don’t have clear evidence that patients are infectious before symptom onset, but we are actively investigating that possibility,” she said.

Messonnier said the risk to the American public for contracting this virus continues to be low.

“We need to be preparing as if this is a pandemic, but I continue to hope that it is not,” Messonnier said.

The CDC confirmed Sunday there are five cases of Wuhan coronavirus in the United States – one in Arizona, two in California and two previously confirmed cases in Illinois and Washington. All five cases were in people who had recently traveled in Wuhan, China.

The CDC has about 75 people still under investigation because they might have the virus, and about 25 others who were found not to have the virus. The CDC is the only lab in the United States that tests for the virus.

China goes into emergency mode as spread of Wuhan coronavirus accelerates

A Chinese girl wears a protective mask as she stands looking towards the Forbidden City, which was closed by authorities, in Beijing.

The death toll from the Wuhan coronavirus now stands at 80, with almost 2,800 cases confirmed across China, as the country initiates emergency procedures to try and rein in the pathogen’s global spread.

Making that task more difficult is the fact that the virus can be spread before any symptoms appear, Chinese health authorities said Sunday, meaning carriers may not realize they are infected before they transmit the virus to others.

Across China, 15 cities with a combined population of over 57 million people – more than the entire population of South Korea – have been placed under full or partial lockdown.

Wuhan itself has been effectively quarantined, with all routes in and out of the city closed or highly regulated. The government announced it is sending an additional 1,200 health workers – along with 135 People’s Liberation Army medical personnel – to help the city’s stretched hospital staff.

Wuhan Mayor Zhou Xianwang said Sunday the number of cases could rise by another thousand.

The disease has also spread widely across China, with almost 70 cases confirmed in the capital Beijing, including a nine-month-old girl – the youngest known case to be confirmed so far.

Concerns grow for rural populations in containing the spread of coronavirus

China is worried about migrant workers who went home to visit family during the Lunar New Year, according to a health expert speaking at the National Health Commission Monday.

The rural population is also of particular concern as those living in rural areas did not have as much experience in dealing with outbreak prevention as the urban populations did during the 2002-2003 severe respiratory syndrome (SARS) outbreak.

SARS is also a type of coronavirus, which causes flu-like symptoms, and can mutate as it spreads from person to person.

People wait in line to clean their hands May 1, 2003.

Between November 2002 and July 2003, SARS infected over 8,000 people and killed 774 around the world.

Around 40% of China’s population live in rural areas, according to Chinese state media Xinhua.

The country also has a sustained wave of migrant workers moving from rural to urban areas for employment, with millions making the switch every year.

China calls on those who were in Wuhan to self-quarantine

People wearing protective facemasks are seen while taking a taxi in Wuhan on January 26.

Chinese officials have called on anyone who was in Wuhan in the last 14 days to self-quarantine and report their time in the city to community leaders, an expert speaking at a Chinese National Health Commission press briefing said on Monday.

The measure is to prevent the further spread of the new coronavirus, which was first identified in the city in December.

On Sunday, Wuhan’s Mayor Zhou Xianwang said that 5 million people left Wuhan before the lockdown due to the Lunar New Year holiday.

At the briefing, Chinese officials also said that arrangements could be made to further extend the holiday period. The holiday observance has already been extended until February 2 to try and prevent the spread of the virus.

Chinese Premier visits hospitals in Wuhan

Chinese Premier Li Keqiang arrived in Wuhan on Monday and is touring hospitals, according to state media.

Li is head of a central government working group set up to tackle the outbreak.

Last week he called on local departments to “go all out” to prevent and control the spread of the disease.  

His visit to Wuhan, ground zero for the outbreak, comes as Chinese authorities announced they would extend the week-long Lunar New Year holiday, which was supposed to run through January 30, to now run until February 2, according to state news agency Xinhua.

On Sunday, Chinese President Xi Jinping chaired a meeting with top officials of the ruling Communist Party on the prevention and control of the Wuhan coronavirus.

During the meeting, Xi said that in facing the grave situation of the rapid spreading epidemic of the deadly new coronavirus, it was necessary to strengthen the centralized leadership of the Party Central Committee. He also demanded that the government at all levels to put people’s life and health as the top priority.

 “Life is of paramount importance. When an epidemic breaks out, a command is issued. It is our responsibility to prevent and control it,” Xi said.

 Xi ordered officials in Hubei province to take more rigorous measures to prevent the virus from spreading and to put all patients in centralized quarantine for treatment. 

HIV and AIDS drugs are being used on Wuhan coronavirus patients in Beijing

Drugs often used to combat HIV and AIDS are being used to treat patients of the Wuhan coronavirus in Beijing, the city’s Health Commission said in a statement. 

Three designated hospitals are using the drugs Lopinavir and Ritonavir to treat patients as part of a test program titled “Pneumonitis Diagnosis and Treatment Program for New Coronavirus Infection (Trial Edition).”

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the US National Institutes of Health told CNN there are currently no proven effective drugs to treat this virus.

The US National Institutes of Health is working on a vaccine against the new virus but it would take a few months until the first phase of the clinical trials get underway and more than a year until a vaccine might be available, Fauci said.

 A team of scientists in Texas, New York and China are also at work on a vaccine, according to Dr. Peter Hotez, a vaccine scientist at Baylor College of Medicine in Houston.

China says coronavirus can spread before symptoms show

China’s health minister Ma Xiaowei made a startling statement Sunday about the Wuhan coronavirus: He said people can spread it before they become symptomatic.

“This is a game changer,” said Dr. William Schaffner, a longtime adviser to the US Centers for Disease Control and Prevention.

It’s much harder to contain a virus – to track down a patient’s contacts and quarantine them immediately – if the patient was spreading the disease for days or weeks before they even realized they had it.

“It means the infection is much more contagious than we originally thought,” said Schaffner, an infectious disease specialist at Vanderbilt University Medical Center. “This is worse than we anticipated.”

Ma didn’t explain why he thinks the virus can be spread before someone has symptoms. If the Chinese health minister is right – and there are those who doubt him – that means the five confirmed cases in the United States might have been infectious while traveling from Wuhan to Arizona, California, Illinois and Washington state, even if they had no symptoms at the time.

Four cases of Wuhan coronavirus now confirmed in South Korea

South Korea confirmed its fourth case of the Wuhan coronavirus on Monday.

The patient is a 55-year-old South Korea man who had tested positive for the virus after visiting Wuhan.

Major airports across South Korea have stepped up efforts to detect signs of the virus, health authorities have also bolstered quarantine and testing facilities.

New details on Arizona coronavirus patient

Another case of coronavirus has been confirmed, in Arizona, the Centers for Disease Control and Prevention said on Sunday, bringing the total to five cases in the United States.

The state health department said the patient is an adult member of the Arizona State University community, though it did not release the patient’s age or gender. 

Dr. Cara Christ, director of the Arizona Department of Health Services, told CNN that the patient had recently returned from travel to Wuhan, and that they called their health care provider once they developed mild respiratory symptoms. Christ added that the patient was asymptomatic – not showing symptoms – during travel.

Health officials decided to test the patient for the coronavirus and sent samples to the US Centers for Disease Control and Prevention on Friday, which were confirmed positive on Sunday.

The patient is currently not hospitalized, but self-isolated at home. Public health officials will be following up with any close contacts of the patient during the time period when they were symptomatic.

Five Wuhan coronavirus cases now confirmed in the US

 A Japan Airlines worker, center, wears a face mask while working inside a terminal at Los Angeles International Airport on January 23,  in Los Angeles, California, where screening was taking place for some incoming international passengers.

Five cases of Wuhan coronavirus have been confirmed in the United States, the US Centers for Disease Control and Prevention said on Sunday.

One new case was confirmed in Arizona and two cases were confirmed in California. Cases had previously been confirmed in Illinois and Washington state. All the cases were in people who had recently traveled to Wuhan, China.

Several people have been infected with the Wuhan coronavirus in the US – including a man in his 30s in Washington state; a Chicago woman in her 60s; a man in his 50s in Orange County, California, a patient in Los Angeles County; and a fifth in Arizona. All had recently traveled to Wuhan, the epicenter of the outbreak.

State and federal officials are following up with anyone who may have had close contact with the person and is at risk of infection.

China's unprecedented quarantines could have wider consequences, experts say

Chinese police officers wearing masks stand in front of the Tiananmen Gate on January 26.

With Chinese authorities warning the coronavirus outbreak is accelerating, placing millions of people in more than a dozen Chinese cities under intense travel restrictions might seem like a good idea.

But historically a mass quarantine is an aggressive response that’s far from perfect. In the past it has led to political, financial and social consequences. 

Quarantines date back to Italy in the 1300s, as the bubonic plague ravaged Europe. In Venice, sailors and ships coming from infected ports were made to wait 40 days before docking in a practice called “quaranta giorni,” or “40 days.”

No quarantine goes perfectly: People criticize quarantines because in practice a virus or bacteria “invariably gets loose,” as do people, said Howard Markel, professor and director of the Center for the History of Medicine at the University of Michigan.

Logistical issues: Just the word “quarantine” can cause panic or hysteria, Markel said. Anyone concerned about a common cold or sniffle will head for hospitals, straining already precious resources. Wuhan officials have already acknowledged local hospitals were struggling to accommodate people seeking medical attention.

Broader financial consequences: Quarantines “are often very economically and financially costly,” said Alexandre White, an assistant professor of sociology and the history of medicine at Johns Hopkins University. The flow of trade in and out of the quarantined zone is halted, and goods in the process of being shipped could go bad – depending on how long it lasts. 

Social impacts: Historically, the aggressive control needed in a quarantine can link the disease to marginalized people and potentially fuel existing anxieties about race and class. There was a “long history of quarantine being misused as a social separator, rather than a public health one,” Markel said.

Trust and cooperation are key: The trust and cooperation of the public is the most important thing for officials to have in a public health crisis, said Lawrence Gostin, a professor of global health law at Georgetown University and director of the World Health Organization’s Center on Global Health Law. Without it, people won’t come in for testing and won’t share the names of people they’ve been in contact with – a vital part of the strategy to prevent the spread of disease.

8 Wuhan coronavirus cases now confirmed in Thailand

Eight cases of the Wuhan coronavirus have been confirmed in Thailand, Deputy Prime Minister and Public Health Minister Anutin Charnvirakul said on Sunday, according to a government statement.

Among the eight, five have already returned home, while three are being treated in the hospitals and supervised by the Ministry of Public Health, the statement says.

Thailand is among the most popular global destinations for Chinese tourists. More than ten million Chinese visit Thailand every year, according to official figures.

80 dead, 2,744 cases have now been confirmed in mainland China

The Wuhan coronavirus continues to spread around the world having already killed dozens of people and infected more than 2,700 people in mainland China.

Here’s the latest numbers:

  • As of the end of the day Sunday, 2,744 cases were confirmed in mainland China.
  • 80 people are dead, all in mainland China.
  • 55 people outside mainland China have tested positive in the following places: Australia (4 cases), France (3 cases), Hong Kong (8 cases), Japan (4 cases), Macao (5 cases), Malaysia (4 cases), Nepal (1 case), Singapore (4 cases), South Korea (3 cases), Taiwan (4 cases), Thailand (8 cases), United States (5 cases) and Vietnam (2 cases)

China’s National Health Commission said 461 people have severe cases of the virus and there are 5,794 suspected cases in mainland China.

Here's the latest on the coronavirus

There are more than 2,700 confirmed cases of the coronavirus and 80 deaths in China. Worldwide concern is mounting about the rate of its spread. Here’s what you need to know:

  • Outbreak in China: 2,744 cases have been confirmed in mainland China, and 80 people are dead. There are full or partial lockdowns in 15 Chinese cities in an effort to limit the virus’s spread.
  • Global spread: There are now 50 cases confirmed around the world, in the United States, Malaysia, Singapore, Thailand, France, Australia, and more. Some countries are trying to evacuate their citizens out of Wuhan, the city at the epicenter of the outbreak.
  • Contagious before symptoms: People can spread the virus before symptoms show, China warned on Sunday – meaning people may have been spreading the virus without knowing they were ill.
  • Wild animal ban: The sale of all wild animals has been banned, the Chinese government announced Sunday. The outbreak has been linked to a market that sold wild animals in Wuhan.
  • Stretched hospitals: Videos and witness accounts in Wuhan show packed hospitals and overworked staff. A new, 1,000-bed hospital is being built on the city’s outskirts, to be ready by February 3. About 1,600 medical professionals are being sent to the city on Sunday and Monday.
