West Nile Fever cases surge in USA

In what is described as the worst season for West Nile Fever virus, the US Centers for Disease Control and Prevention is reporting โ€œthe largest West Nile virus outbreaks ever seen in the United States.โ€ Infected birds, mosquitoes or humans have been reported by 47 states, with most of the transmission occurring in Arizona, California, Texas, Mississippi, Louisiana, South Dakota and Oklahoma. Only Alaska, Hawaii and Vermont remain free of the virus so far. This year, there have been 1,118 human infections with 41 deaths.

Advice

While the risk for the general traveller is low, travellers to areas where this virus has been found can still reduce their risk of exposure by taking all necessary precautions to avoid mosquito bites. There is no vaccine or treatment for West Nile fever.
