Third Human West Nile Virus Case Confirmed in Suffolk County

In late August, a resident of the Town of Islip—someone over the age of 50—started feeling the tell‑tale aches and fevers that often signal a West Nile virus infection. By the time doctors ran the necessary tests, the diagnosis was clear: the mosquito‑borne illness had taken hold.

Health officials with the Suffolk County Department of Health Services confirmed that this is the third human case reported in the county this year. The patient was admitted to a local hospital for close monitoring, but, thanks to supportive care, has now been released and is continuing recovery at home.

West Nile virus isn’t a new worry for Long Islanders; it spreads through the bite of an infected mosquito. Roughly one in five people who contract the virus actually develop symptoms, which can range from mild fever, headache, and body aches to a rash and swollen lymph nodes. In more serious instances—especially among folks over 50, those with chronic health issues, or anyone with a weakened immune system—the virus can cause high fever, neck stiffness, confusion, tremors, muscle weakness, or even paralysis.

There’s no magic cure for West Nile virus. Doctors focus on easing the symptoms—fluid replacement, pain relievers, and close observation for any neurological changes. The CDC advises anyone who experiences severe symptoms, like a sudden high fever or trouble moving, to seek medical help right away.

With mosquito season stretching from June through November in Suffolk, officials are urging residents to stay vigilant. Simple steps—slap on EPA‑approved insect repellent, wear long sleeves and pants during dusk, fix any torn screens, and dump standing water from buckets, birdbaths, or old tires—can make a big difference.
