STATE COLLEGE — A Penn State University student diagnosed with bacterial meningitis is improving.

A university spokeswoman says the 20-year-old male was upgraded over the weekend from critical to serious condition at Geisinger Medical Center in Danville.

The school said Monday there have been no other cases.

At East Stroudsburg University, a male student there has also been hospitalized for meningitis.

Health workers at each school are working to identify anyone else who may be at risk.

Meningococcal meningitis is a contagious and potentially fatal infection of the central nervous system.
