The Thomas Jefferson Health District discovered a dead crow on Garth Road on September 5th, and have now confirmed that it was infected with West Nile Virus. West Nile made its first American appearance in New York in 1999, and has been spreading down the east coast ever since. The rare disease, which affects birds, horses and humans, is spread by infected mosquitos. There is neither a vaccine nor a specific treatment. The county has stressed the importance of removing all sources of standing water, where mosquitos are likely to spread. It ia also important to report dead birds to the county so that they can be aware of any further infections. WINA has the story.
