The Massachusetts Department of Public Health says West Nile virus has been found in mosquito samples collected in Pittsfield.
Mosquitoes in some areas of Virginia Beach have tested positive for West Nile Virus.
The results for the second crow came back positive four days later.

Use an insect repellent containing DEET, picaridin, oil of lemon eucalyptus or IR3535.
People are also advised to stay indoors at dawn or dusk, when mosquitoes are most active.
Install or fix screens on windows and doors to keep mosquitoes out of the home. The greatest concentration of mosquito-positive reports is in the southeastern part of the state, and particularly in the counties closest to the Maryland border, where York County has already reported more than 40 mosquitoes positive for West Nile.
Keep mosquitoes from laying eggs inside and outside of your home.
The peak time of year for transmission of WNV, along with Delaware's other mosquito-borne disease of concern, Eastern equine encephalitis (EEE), is from about mid-August into mid-October.
While the majority of people infected with WNV have no symptoms, the virus can cause serious symptoms in some people, especially those over 65 and those who are immunocompromised.
For those that get West Nile, there is no vaccine or specific treatments though over-the-counter pain relievers can be used to reduce fever and relieve various symptoms.
