Philadelphia, February 15: According to Penn University officials, the three students who were hospitalized for meningitis infections last week were showing marked improvement, and the condition of two other students hospitalized with flu-like symptoms was stated as not critical.

Philadelphia -- The University of Pennsylvania has warned its students that three of their peers have been diagnosed with meningitis, a school spokeswoman says.

University spokeswoman Phyllis Holtzman said as a precaution the school canceled all Greek and school-sponsored events for the weekend and is offering medical assistance at the college's special health services clinic, The Philadelphia Inquirer reported Sunday.

"We believe the common point is that the students had been at a Greek event or in close contact with someone who was," Holtzman said.

The college officials said one of the three students hospitalized with meningitis was in critical condition, while the other two were stable.

Penn freshman Sara Schults told the Inquirer the meningitis scare has students concerned for their health and choosing to be cautious about communal campus activities.
