In New York State, most West Nile virus-positive birds have been American crows. The State Health Department is using dead crow sightings to track West Nile virus, so it s important to report any dead crows to your local health department. Not all dead crows need to be tested for West Nile virus. There is no evidence that birds can transmit West Nile virus to people, but gloves should be worn when handling any dead bird or mammal because of the possiblity of other diseases. West Nile virus has been confirmed in some domestic animals, including pet birds, dogs and cats.
Horses can become seriously ill, if infected.
It is important to remember that birds and animals cannot transmit West Nile virus to people. Remove all discarded tires on your property. Used tires are very significant mosquito breeding sites. Drill holes in the bottoms of recycling containers that are kept outdoors. Make sure roof gutters drain properly, and clean clogged gutters in the spring and fall.
