Americans are being warned about a potentially deadly virus surging across the country and is only expected to worsen as the US experiences some of its hottest summer weather. A 'higher-than-expected' number of dengue fever infections - spread by the bites of infected mosquitoes - have been recorded in the US so far this year, with approximately 2,240 cases detected in at least 38 states, compared to 3,040 over the whole of 2023.
