West Nile virus detected in Greene County
West Nile virus has been detected in mosquitoes in Greene County.
The Greene County Conservation District said four mosquito samples tested positive for West Nile virus – two in Cumberland Township, and one each in Morgan Township and Waynesburg Borough.
At this time, there are no known human cases of West Nile virus reported in the county.
The virus has been detected in a majority of counties in Pennsylvania, including Washington and Fayette, according to a map from the state Department of Environmental Protection.
Zachary Basinger, environmental permitting manager for the conservation district, said the district, with the DEP, is continuing to monitor mosquito populations and is conducting targeted mosquito control, including barrier sprays and larvicide treatment.
West Nile is a mosquito-born disease that was first detected in Pennsylvania in 2000, according to the DEP.
Most people who become infected do not develop symptoms, but some may experience mild, flu-like symptoms such as fever, headache, body aches, and fatigue. In rare cases, particularly in older adults and people with weakened immune systems, the virus can cause encephalitis or meningitis.
Residents are advised to take precautions when outdoors during dusk and dawn, such as applying insect repellent and wearing long-sleeved shirts and pants. Health officials recommend that anyone who suspects an infection consult a healtcare provider.
Homeowners can reduce mosquito breeding habitats by eliminating standing water around their homes, draining or getting rid of items capable of holding standing water, such as discarded tires, changing water in birdbaths each week, making sure water is cleared from gutters, and ensuring window and door screens are in good condition.
“There no reason to be alarmed right now,” said Basinger, noting there were 26 positive West Nile tests and that September is the peak period for human transmission of West Nile virus.
