New method could improve US forecasting of West Nile virus

West Nile virus is the most common mosquito-borne illness in the continental United States and can in rare cases lead to a much more serious disease with an approximately 10% fatality rate. West Nile virus neuroinvasive disease (WNND) has resulted in about 3,000 deaths since its introduction to the country in 1999, but to date no national forecast for the disease exists.
