The Chelsea Board of Health has issued a West Nile virus alert.
All Chelsea residents are urged to be as careful as they can and to avoid being bitten by mosquitoes which carry the sometimes deadly disease.
The hours from dusk to dawn are the peak biting times.
Applying insect repellant is the most obvious way to ward off unwanted mosquito bites.
WNV is a disease most commonly transmitted to humans by the bite of an infected mosquito. The mosquitoes that carry this virus are common throughout the state, and are found in urban as well as more rural areas. While WNV can infect people of all ages, people over the age of 50 are at higher risk for severe infection.
Again, the Chelsea Board of Health has issued a warning about the elevated risk of West Nile virus in the city.
Take all precautions to cover oneself and to protect oneself from bug bites.
If you or your children are repeatedly bitten or feel sick following a mosquito bite, get yourself or your child to the MGH or Beth Israel Clinic immediately.
