Here's some additional information on mosquitoes:
A mosquito pool is defined as at least one insect testing positive for the virus out of a test batch of up to 100 mosquitoes per trap.
Pennsylvania has conducted testing of mosquitoes for the virus since 2000. The worst year for human deaths from the virus was 2003, when nine people died out of 236 reported cases.
Thomas W. Simmons, Ph.D. has been part of state efforts to trap mosquitoes for study since 2005, and is currently studying water mite parasitism of mosquitoes in collaboration with the state Department of Environmental Protection.
The disease is spread from the bite from a common female mosquito drawing blood from humans.
