Spread of West Nile Fever is slowing in USA (update)

The US Centers for Disease Control and Prevention reported that, although the number of cases of the mosquito-borne West Nile virus in the continental United States continues to grow, the spread of the infection in the population appears to be slowing. To date, 4,891 people have contracted the disease, up from 4,725 a week ago. There have been 4 more deaths bringing the total death toll to 223.

Although colder weather in some parts of the country will decrease the mosquito population, travellers should still exercise caution in some areas. Since there is no vaccine or treatment for infections with West Nile fever virus, travellers to areas where the West Nile Fever virus has been found can reduce their risk of exposure to this virus by taking all necessary precautions to avoid mosquito bites.
