Pennsylvania's first probable case of West Nile virus in 2017 has been reported in Montgomery County.

The patient, a 52-year-old man in Horsham Township, suffered from encephalitis/meningitis, according to the state's West Nile Virus Control Program.

He was hospitalized, recovered, and was discharged, said Kaitlyn Foti, Montgomery County spokeswoman.

"We typically see between one and three cases" each year, said Julie Paoline, Montgomery County director of communicable disease control and prevention.

Starting in April, the state will begin to monitor mosquito activity. July is the peak of the season, which usually ends in late October around the first frost, Paoline said.

In 2016, there were 16 cases of the mosquito-borne disease throughout the state. In 2015, there were 30 cases, according to the state.

The type of mosquito that transmits West Nile is most active at dawn and dusk. Using DEET-containing insect repellents, and covering exposed skin with lightweight clothing, are recommended to avoid bites. To keep mosquitoes from getting in the house, check that window and door screens are secure and in good condition.

To reduce breeding grounds, keep rain gutters and downspouts clean and free of leaves. Also remove unused tires and other items that could collect water.

"Make sure you get rid of that stagnant water around property," Paoline said.
