A case of mumps was reported at Delaware City Schools late Wednesday as the number of mumps cases in central Ohio climbed to 193.
In Delaware County, the number of reported mumps cases reached 20, including two cases connected to an outbreak originating at Ohio State University. The majority of cases continued to be reported in Franklin County: 110 cases related to the OSU outbreak in Columbus with 3 cases reported in other areas of the county and 35 community-outbreak cases in Columbus with 15 reported in other areas of Franklin County.
DCS spokesperson Jennifer Ruhe said the district was notified of the isolated case at Conger Elementary School Wednesday when a parent called in. The district was prepared for such an eventuality: Notices were sent out by e-mail to staff and families district-wide on Wednesday night, and notes were sent home with Conger students on Thursday.
Ruhe said the district has been working closely with the Delaware General Health District since the outbreak began. The first case of mumps was identified at OSU in January, and an outbreak was declared in Franklin County in March. ODH declared a community-wide outbreak including Delaware County April 2.
Ruhe said DCS has not had a reported case of mumps among students since 2008, but the district has plans to handle cases when they do arise. The district began organizing health records and creating lists of students who are not immunized and who are immunocompromised in March under the direction of the health department.
ODH said the most important message for the public is still vaccination with the measles, mumps and rubella vaccine (MMR). DCS officials estimated 96 percent of its student body has been vaccinated based on health records.
A two-dose MMR series is recommended for children; the first dose is given between 12 and 15 months followed by a second dose between 4 and 6 years of age. Students attending post-secondary school are recommended to get a booster due to the possibility of transmission in close living quarters such as dorms. Health care workers are also encouraged to get a booster MMR.
For those vaccinated, the two doses are considered 90 percent effective.
Cases of mumps related to the OSU outbreak have also been recorded in Athens, Belmont, Fairfield, Hamilton and Licking counties. Community-related cases have been recorded in Marion, Union, Allen and Licking counties as well.
Symptoms of mumps include fever, body aches, fatigue, swelling of salivary glands, or pain with chewing or swallowing.
Up to 15 percent of people with mumps may also experience stiff neck and headache.
Men may also experience orchitis, a testicular inflammation that causes pain, swelling, nausea, vomiting and fever. Some women may experience symptoms of inflammation of the ovaries and breasts.
Symptoms usually begin 14 to 18 days after catching the virus, but the virus can be spread to others before symptoms even occur, according to the Centers for Disease Control and Prevention (CDC). Transmission is likely before the salivary glands begin to swell and within five days after the swelling starts.
About a third of patients will show mild symptoms or no symptoms.
If symptoms do occur, residents are encouraged to contact the Delaware General Health District, at 740-368-1700, or their primary care provider for vaccine availability.
