Town Issues Warning About West Nile Virus

WEST HARTFORD, CT — Mosquitoes in West Hartford have tested positive for West Nile virus, prompting local health officials to urge residents to take precautions against mosquito bites.

The Town of West Hartford announced the detection Thursday and advised residents to use insect repellent, wear long-sleeved shirts and long pants, and limit outdoor exposure from dusk to dawn.

Officials also recommended using air conditioning when possible, installing or maintaining window and door screens and eliminating standing water around homes to reduce mosquito breeding sites.

West Nile virus is primarily spread to people through the bite of an infected mosquito. Most people who become infected — about 80% — do not develop symptoms.

About 20% develop a mild illness that can include fever, headache, body aches, joint pain, vomiting, diarrhea, or a rash.

Most people with mild illness recover completely, although fatigue and weakness can persist for weeks or months.

Symptoms usually begin two to six days after a bite from an infected mosquito but can appear anywhere from two to 14 days afterward.

Symptoms may take longer to develop in people with weakened immune systems.

A small number of people can develop severe illness affecting the central nervous system, potentially resulting in hospitalization or death.

Older adults and people with certain underlying medical conditions are at greater risk of severe illness.

People experiencing high fever, neck stiffness, muscle weakness, confusion, or tremors should seek immediate medical attention.

There are no medications specifically available to treat West Nile virus. A healthcare provider can order laboratory testing to help diagnose an infection.

The town did not identify where in West Hartford the positive mosquitoes were collected or report any human cases in its announcement.

Health officials are directing residents to the Centers for Disease Control and Prevention's West Nile virus resources for additional information about symptoms, prevention, and treatment.
