West Nile Virus Fact Sheet Updated

Format: Fact Sheet
Institute: National Institute of Allergy and Infectious Diseases (NIAID)

The West Nile virus causes an infectious disease that made its first appearance in the United States in 1999. No specific vaccines or treatments exist for the disease. Faced with a potentially deadly illness spreading quickly across the nation, scientists and public health officials have accelerated research in developing tools to prevent and treat West Nile disease.

NIAID has updated its West Nile virus fact sheet to reflect new details about vaccine trials, the number of drugs screened to treat the disease, research projects, and statistics.
