Department spokeswoman Christine Cronkright said Thursday that most – but not all – of those infected reported they had been swimming in the lake during the weekend of July 30-31.

Cronkright said all but one of the cases are in children. Nine cases are from Pennsylvania, and two are from Maryland.

Health and state park officials continue to search for the source of the outbreak. The lake has been closed for swimming, wading, boating and fishing until further notice as a precaution.
