9.14.2002: West Nile Virus - Biodefense and Epidemiological Tracking  Includes comparative maps of spread from 1999-2002 and current (as of 9.11.2002) USGS United States maps for bird, human, mosquito, sentinel and veterinary cases. Map Graphics take time to load. 12.14.99: West Nile Virus May Be New Deadly Strain, USGS Tells Congress: Recent crow die-offs suggest the West Nile virus which emerged in New York in late August could be more deadly to North American bird species than to species in Africa, the Middle East and Europe, where the virus is normally found, a USGS scientist reported today at a congressional field hearing held in Connecticut by the Senate Committee on Environment and Public Works.

According to the AVMA, article on 10.21.99 entitled "Veterinarians key to discovering outbreak of exotic encephalitis":

In late August came the first reports of a human encephalitis outbreak in New York City and nearby Nassau and Westchester counties. The CDC would initially attribute the cause to the mosquito-borne St Louis encephalitis, which has been seen before in the Midwest and Southeast but never New York.

Around that same time, more than 70 miles away in the Riverhead area of Long Island, 22 horses began showing neurologic signs of an encephalitic infection — lethargy, weakness in the hindquarters, and convulsions. Initially, local veterinarians suspected the horse deaths and illnesses were caused by equine protozoal myelitis. Later, on Oct 19, after 13 of the horses had died or were euthanatized, the USDA-APHIS announced they all tested positive for the West Nile virus. Horses are highly susceptible to the virus — a 1996 report from Egypt indicated 40 percent mortality.
