The Missouri Department of Health reports three American crows have been found positive for West Nile virus over the past few weeks. Two were submitted by public health officials in St. Louis County and one was submitted by officials in the city of St. Louis. This is in addition to five American crows from the St. Louis area that were found to be carrying the West Nile virus in early October. Specimens of birds from other areas of the state have so far been negative for the virus. To date, there have been no confirmed cases of West Nile viral infection in humans or other animals in Missouri.
