Health authorities are urging residents to take preventive measures to reduce the risk of infection.

Key takeaways

  • Suffolk County reported its first human West Nile virus case of the season.
  • Mosquito samples testing positive for the virus are on the rise.
  • West Nile virus can cause mild to severe illness, especially in older adults.
  • Prevention focuses on avoiding mosquito bites and reducing standing water.

What is West Nile virus?

West Nile virus is a mosquito-borne disease that can cause a range of symptoms, from none at all to severe neurological illness. It is primarily transmitted through the bite of an infected mosquito. Most people infected with the virus do not develop symptoms, but about one in five may experience fever, headache, body aches, joint pain, vomiting, or rash. In rare cases, the virus can lead to encephalitis or meningitis, which can be life threatening.

According to the original report from RiverheadLOCAL, the Suffolk County health department confirmed the human case and noted that mosquito surveillance has detected the virus in multiple locations. The report did not specify the age or condition of the patient.

Symptoms and risk factors

Most people infected with West Nile virus show no symptoms, but some develop mild flu-like illness. People over 60 years of age and those with certain medical conditions, such as cancer, diabetes, or kidney disease, are at higher risk for severe illness. Symptoms of severe disease can include high fever, stiff neck, disorientation, tremors, muscle weakness, and paralysis. Anyone experiencing these symptoms after being bitten by a mosquito should seek medical care promptly.

How to prevent mosquito bites

Health officials recommend several steps to reduce the risk of West Nile virus infection. Using EPA-registered insect repellents, wearing long sleeves and pants, and avoiding outdoor activity during peak mosquito hours (dusk to dawn) can help. Removing standing water from around homes, such as in bird baths, flower pots, and gutters, eliminates mosquito breeding sites. Ensuring window screens are intact also prevents mosquitoes from entering homes.

The Suffolk County health department continues to monitor mosquito activity and apply larvicide treatments where needed. Residents are encouraged to report areas of standing water or dead birds to local authorities.

Frequently Asked Questions

Is there a vaccine for West Nile virus?

No vaccine for West Nile virus is currently available for humans. Prevention depends entirely on avoiding mosquito bites and controlling mosquito populations. A vaccine exists for horses, but not for people.

How is West Nile virus diagnosed?

Diagnosis is typically done through a blood or spinal fluid test that looks for antibodies to the virus. Healthcare providers may order these tests if a patient has symptoms consistent with West Nile virus and a recent history of mosquito exposure.

Can West Nile virus spread from person to person?

West Nile virus is not spread through casual contact like coughing, sneezing, or touching. It can be transmitted through blood transfusion, organ donation, or from a pregnant woman to her baby, but these routes are rare. The main transmission route remains mosquito bites.
