West Nile virus is transmitted to humans by the bite of an infected mosquito. Most infected people will experience mild or no symptoms. Some can develop mild to severe symptoms including headache, neck stiffness, vision loss, high fever, confusion, muscle weakness, paralysis and potentially death.
Everyone is urged to take precautions to avoid mosquito bites. Individuals 50 and older, as well as those with compromised immune systems, are urged to take precautions to avoid mosquito bites.
Deceased birds could indicate the presence of West Nile virus. To report a deceased bird on your property, contact the Suffolk County Department of Health Services Bureau of Public Health Protection at 631-852-5999 from 9 a.m. to 4 p.m. Monday through Friday. Residents are encouraged to submit a photo of the bird. To report mosquito problems, contact the Department of Public Works Division of Vector Control at 631-852-4270.
