( CNN ) -- An outbreak of mumps , first reported at The Ohio State University , has spread beyond campus and into the community , health officials said . As of Monday , 63 cases of mumps were reported in Franklin County , Ohio , according to Columbus Public Health . Forty-five of those are linked to the university outbreak , said Jose Rodriguez , spokesman for the health department . `` The university cases have occurred in men and women between the ages of 18 and 48 , while the community cases have occurred in residents of Columbus and Franklin County between the ages of 4 and 50 , '' the department said in a statement . The first OSU cases were reported on February 11 , Rodriguez said Monday . CNN Health Library : Learn more about mumps . The department is working with other universities to make sure they are ready to vaccinate members of the university community and promote infection control measures . The most important of those are : wash your hands , cover your cough and stay home if you 're sick , he said . Mumps is `` a highly infectious disease '' that spreads the same way as a cold or flu does -- through respiratory droplets when someone coughs or sneezes . Five days of isolation is required , `` and that can be complicated in a university setting , '' he said . Even more frightening -- one-third of cases have no symptoms , he said . The 63 cases are those who became ill ; others may be spreading the disease unknowingly . OSU students went on spring break `` right as this was exploding , '' Rodriguez said , and local health officials contacted the Centers for Disease Control and Prevention in Atlanta to warn other departments to be on the lookout . `` The numbers doubled when the kids came back , '' he said . Cases of mumps were also reported at Fordham University in New York last month . Some 97 % of those in the Ohio outbreak have been vaccinated , he said . The vaccine is 80 % to 90 % effective , meaning 10 % to 20 % of people who have been vaccinated might become ill anyway . Mumps typically begins with a fever , headache , muscle aches , fatigue and loss of appetite , which is followed by the swelling of salivary glands , according to the CDC . There is no specific treatment for mumps , and patients usually recover after a week or two , but occasionally the disease can cause serious complications such as encephalitis , meningitis , deafness or inflammation of the breasts or ovaries in girls who have reached puberty , the CDC said . Children should receive their first vaccine for measles , mumps and rubella at 12 to 15 months , and the second dose at 4 to 6 years , according to the CDC . Columbus Public Health is urging those at high risk -- including those who have not been vaccinated or those who only received one dose -- to get vaccinated . 2013 : East Coast mumps outbreak linked to nightclub .
