West Nile Virus

Updated August 28, 2007


West Nile Virus (WNV) infects mosquitos, which can transfer it to humans, birds, horses and other animals. It is common in Africa, West Asia, and the Middle East, and since 1999 it has been found in the United States.

In humans, the virus often causes only a mild infection -- characterized by fever, headache, tiredness, aches and rash -- that clears up without further treatment. But some patients develop severe infections resulting in neurological disease and even death.

The links on this page provide up-to-date information on this public health hazard and on measures by the FDA and other government agencies to protect humans and animals against WNV.
