Story summary

An outbreak of the contagious disease mumps occurred at San Diego State University, affecting several student athletes. The university confirmed three cases and reported two probable cases without identifying specific sports or individuals involved. Dr. Tanushree Ghosh, medical director of the school’s health services, stated that infected students are no longer considered contagious. Mumps, caused by a virus targeting salivary glands, can lead to severe complications like brain, testicle, and ovary inflammation. While the MMR vaccine offers protection against mumps, vaccinated individuals might still contract the disease due to waning immunity over time. In response, the university is hosting a clinic for screening and booster shots for those potentially exposed.
