New Bedford is taking precaution against diseases spread by mosquitoes.
State health officials, a part of the Bristol County Mosquito Control Project, sprayed pesticides in parks, including Buttonwood Park, Brooklawn Park and Fort Taber, and throughout downtown early this morning.
Mosquitoes can carry diseases like West Nile Virus and Eastern Equine Encephalitis, or EEE, that can be transmitted to humans.
Symptoms of West Nile Virus include fever, headache and neck stiffness.
EEE is much rarer, but serious. The virus can cause sudden onset of headache, high fever, chills and vomiting, but can become more severe causing brain swelling.
So far this summer, some mosquitoes have tested positive for EEE in Rhode Island. West Nile Virus was detected in mosquitoes in Massachusetts and Connecticut.
To protect yourself against mosquitoes, health officials recommend using insect repellent, repairing torn window screens, wearing long sleeves and pants, and draining standing water, which mosquitoes use to breed.
