2 More Cases of West Nile Virus Reported In Suffolk County

BROOKHAVEN, NY — Two additional cases of West Nile virus have been confirmed in Suffolk County, totaling in seven positive cases this season, according to Suffolk County Commissioner of Health Services Dr. Gregson Pigott.

The first of two new cases is a Town of Southold resident who is over the age of 50. The resident became ill with West Nile virus in early October, was hospitalized in mid-October, and has almost fully recovered at home.

The second of the two cases is a Town of Brookhaven resident who became ill in late October and remains hospitalized.

Health officials have previously reported five cases of West Nile virus this season, two from the Town of Huntington, one from the Town of Brookhaven, and two from the Town of Babylon. The two Huntington residents were over the age of 50 and the others were under the age of 50.

“Mosquito season ended on November 1, but now is a perfect time for Suffolk County residents to repair screens, clean yards, and make solid plans to reduce the number areas where mosquitoes can breed around their homes in order to avoid being bitten and contracting mosquito-borne illness,” said Pigott.”

West Nile virus is transmitted to humans by the bite of an infected mosquito. It is estimated that 20 percent of those who become infected will develop clinically noticeable symptoms of West Nile virus disease.

Mild symptoms may include fever, headache and body aches, skin rash and swollen lymph glands. More severe symptoms include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis.

Individuals who are most at risk for severe infection include those over 50 years of age and those with chronic illness or compromised immune systems. Suffolk County residents are urged to take precautions to avoid being bitten by mosquitoes during mosquito season, which extends from June 1 through November 1.

To avoid mosquito bites, use insect repellent containing DEET*, spray clothing with repellent containing permethrin, avoid going outside from dusk to dawn when most mosquitoes are active, wear long sleeves and long pants when nighttime activity is unavoidable, eliminate standing water from flowerpots, clogged gutters, recycle bins, birdbaths, toys, and swimming pool and hot tub covers.
