Dead Crow Tests Positive For West Nile In Columbia County

9/14/17 – A dead crow found in Columbia County found on September 2nd has tested positive for West Nile virus. The Columbia County Health and Human Services reports that it is the first bird that tested positive for the mosquito-borne illness in the county since surveillance for the mosquito-transmitted virus began on May 1. Health Officer Susan Lorenz says the positive bird means that residents of in the area need to be more vigilant in their personal protective measures to prevent mosquito bites. West Nile virus is spread to humans through the bite of an infected mosquito. Mosquitoes acquire the virus by feeding on infected birds. Lorenz says the best way to avoid the disease is to reduce exposure to and eliminate breeding grounds for mosquitoes. A horse from Dodge County recently tested positive for West Nile, confirming that infected mosquitoes are in the area.
