Have you been vaccinated? Public-health officials confirmed that almost two dozen people at Ohio State University have been newly infected with the mumps. Three individuals had been temporarily hospitalized but have since been released. While it is unclear how the outbreak began, authorities are focusing on those infected to find any links and urge students and faculty to take extra precautions. The disease, which typically spreads through saliva, can infect anyone who has not been previously infected or vaccinated. Symptoms of the contagious disease include fever, muscle aches, and headaches.
