CLEMSON, S.C. (AP) — Officials say fans who went to Clemson for last month’s football game against the University of South Carolina may have been exposed to mumps.

The state Health and Environmental Control Department tells news outlets people who visited or lived at Clemson University or Tri-County Technical College from Nov. 21-29 may have been exposed to the viral infection.

The department says in a statement that mumps can be spread through saliva, coughing, sharing food and drinks or other ways. Officials recommend washing hands frequently and getting the MMR (measles-mumps-rubella) vaccine.

Officials say one mumps case has been confirmed in connection to Clemson and Tri-County Tech.

Joe Galbraith, Clemson’s associate vice president for strategic communications, says students without an immunization record on file are being contacted directly.
