Mosquitos in Boston test positive for West Nile

Boston health officials are urging people to protect themselves from mosquitoes after samples of the insects tested positive for West Nile virus.

The Boston Public Health Commission said the positive samples were taken in Roxbury, Jamaica Plain, Roslindale and West Roxbury.

There have been no human cases of the mosquito-borne disease in the state this year. The best way to protect yourself from the disease is to avoid getting bit by a mosquito.

Mosquitos are most active from dusk to dawn, so limit your time outside then. Wear clothing that covers your legs and arms. Use EPA-approved inspect repellant. Empty out anything that collects large amounts of water in your area, like kiddie pools or bird baths.

Most people infected with West Nile will not experience symptoms. In some cases, patients have headaches, fever, nausea and body aches. Those older than 50 are at the highest risk of developing serious symptoms, according to the Boston Public Health Commission.

“We are working closely with our partners at the State to monitor mosquito test samples and keep residents updated about the risk of West Nile," Dr. Bisola Ojikutu, commissioner of Public Health and executive director of the Boston Public Health Commission, said in a statement.

West Nile has also been detected in mosquitos in Worcester and Quincy.
