West Nile Virus Mosquitoes Detected in New York City

For the first time this season, the Health Department has detected New York City mosquitos carrying the West Nile virus.

Infected mosquitoes were collected from the Douglaston and College Point neighborhoods in Queens and in Old Town on Staten Island. Though no human cases have been reported this season, the Department has scheduled aerial larviciding to kill immature mosquitoes before they can bite.

“Now that West Nile virus has returned to New York City, it is important to take simple precautions to protect you and your family,” said Health Commissioner Dr. Mary Bassett. “During warm weather, mosquitoes can breed in any still water that stands for more than four days, so the most effective way to control mosquitoes is to eliminate standing water.”

The Health Department will increase mosquito surveillance by setting up additional traps, treating catch basins in the affected areas, and applying larvicide to the city’s catch basins, marshlands and areas with standing water.

The West Nile virus can cause serious complications including neurological diseases, as well as milder flu-like illness with headache, fever and fatigue, weakness and sometimes rash. If you believe that you have symptoms of the virus, see your doctor right away.

“New Yorkers are also encouraged to mosquito-proof their homes, wear mosquito repellent and cover their arms and legs if they’re outside at dawn or dusk,” cautioned Dr. Bassett. “New Yorkers over 50 should be especially cautious, as they are more likely to develop serious illness if they contract the virus.”

Tips for Reducing Exposure to Mosquitoes:

• Use approved insect repellents containing picaridin, DEET, oil of lemon eucalyptus (not for children under three), and products containing the active ingredient IR3535
• Attach screens to windows and make sure they are free of tears and holes
• Eliminate standing water and dispose of containers that can collect water. Standing water is a violation of the New York City Health Code.
• Keep roof gutters clean and drained
• Clean and chlorinate swimming pools, outdoor saunas and hot tubs; keep them empty or covered when not in use, and drain water caught in pool covers
• Report standing water by calling 311 or visiting the health website.
