State health officials on Monday reported Montgomery County's first human case of West Nile virus.

The patient is a woman who became ill Aug. 19, said state DEP spokeswoman Lisa Kasianowitz. Citing privacy concerns, Kasianowitz declined to provide more information about the woman or where in Montgomery County she contracted the virus.

Also unclear was the woman's medical condition. One of the 18 people to get West Nile virus in Pennsylvania this year, a Luzerne County man, has died.

A Lancaster County human case also was reported Monday, as were 44 positive tests in mosquito samples around the state.

Montgomery County reported no human cases of West Nile virus in 2011. Four were reported in 2010.

The Montgomery County Health Department's website provides a variety of West Nile virus tips and facts.
