West Nile virus detected in southern Maine mosquito pool

Health officials have confirmed a mosquito pool in southern Maine has tested positive for West Nile virus.

Maine Center for Disease and Prevention on Wednesday said a group of between one and 50 mosquitoes collected Aug. 21 in Kittery tested positive for the virus.

The state this week announced an adult from Cumberland County tested positive for the virus and is recovering in the hospital.

The agency says the patient probably contracted the disease out-of-state. At least four cases of West Nile virus have been confirmed this season in Massachusetts. There have been confirmed cases in Connecticut this season as well.

Most infected with the virus show no symptoms. Others can develop fever and aches.

Officials advise avoiding mosquito bites by getting rid of standing water and wearing repellent.
