AUGUSTA (AP) — The Maine Center for Disease Control and Prevention Control says West Nile virus has been confirmed in a Pennsylvania resident who was visiting Maine.

State epidemiologist Dr. Stephen Sears says a federal lab on Tuesday confirmed West Nile in a Philadelphia woman who developed symptoms while visiting Maine earlier this month. He says the woman was treated at a Lincoln County hospital and has since recovered.

Sears says it’s believed that the woman contracted the virus before she arrived in Maine, so she’s being counted as a Pennsylvania case instead of Maine case.

So far, there has been no documented case of someone contracting West Nile in Maine, but mosquitoes bearing the virus have been confirmed in the state.
