A local resident has tested positive for West Nile virus, the Windsor-Essex County Health Unit reported Friday.
A Middlesex County woman in her 60s also had the disease but was not hospitalized.
On Tuesday, DPH raised the risk level for West Nile virus from low to moderate in every MA city and town.
This marks the first clinically diagnosed and lab-confirmed human case for the area in 2018.
Although mosquitoes are active throughout the summer, West Nile virus typically doesn't begin to appear until late summer, said Nicholas Rupp, department spokesman.
West Nile virus turned up in a collection of mosquitoes in the Goose Hollow neighborhood north of Pasco.
People can take steps to protect themselves and their loved ones from illnesses caused by mosquitoes. Symptoms usually begin three to 14 days after infection. "New York City has one of the most comprehensive mosquito control programs in the nation". Apply insect repellent containing DEET, picaridin, oil of lemon eucalyptus, or IR 3535 according to label instructions. Keep mosquitoes outside by having tightly-fitting screens on all of your windows and doors.
Dusk to Dawn - Avoid exposure during peak Culex mosquito feeding times, from dusk through dawn.
Drain - Remove standing water in your yard or garden to minimize mosquito breeding areas.
Dress - Wear long sleeves and trousers to keep mosquitoes from biting.
