AUGUSTA The Maine Centers for Disease Control and Prevention said it is investigating a confirmed case of mumps at York High School, the first case identified in Maine in 2019.

The CDC said the unvaccinated individual became ill March 9 and laboratory testing confirmed mumps March 15. The individual was not isolated during the beginning of his or her illness and may have exposed others to the virus at York High from March 6-8 and at the unified basketball game at Massabesic High School March 7, the CDC said.

The individual acquired mumps while traveling outside the United States, the CDC said.

Superintendent of Schools Lou Goscinski said Friday that there have been no reported cases to date at Village and Coastal Ridge elementary schools or at York Middle School. As a precaution, he said, he alerted all staff, parents and guardians of K-12 students.

According to the CDC, mumps is a highly contagious viral disease characterized by fever, headache and swelling of the salivary glands. Other symptoms include low-grade fever, fatigue, muscle aches and loss of appetite. Complications can include redness and swelling of the testicles in males, inflammation of the brain or membrane covering the spinal cord, inflammation of the ovaries in females, loss of pregnancy, and permanent hearing loss.

Symptoms usually appear 16 to 18 days after infection, but can range from 12 to 25 days. There is no specific treatment for mumps and anyone with symptoms should contact their health care provider, the CDC stated.

The CDC said mumps is spread through saliva or mucus and objects or surfaces touched by an infected person. People at highest risk are those who share personal items with or who in close contact with an infected individual.

Maine CDC is working to notify close contacts and has provided recommendations for YHS. The general public, including those who live in the same community, have a low risk of getting mumps from this case, the CDC said.

Mumps can be prevented through vaccination. Individuals should review their medical records and ensure they are up to date on all vaccines including the MMR vaccine, which protects against mumps, said State Epidemiologist Dr. Siiri Bennett.

The CDC suggests precautions to reduce risk of mumps:

Do not share food, drinks, water bottles, utensils or other personal items that may contain saliva.

Wash frequently with soap and water or use an alcohol-based hand sanitizer. Clean and disinfect objects and surfaces that may be contaminated with germs.

Cover your nose and mouth with a tissue when you sneeze or cough. If a tissue is not available, sneeze or cough into your upper sleeve or elbow, not your hands.

Get vaccinated with two doses of MMR vaccine if you havent already.

People who get mumps should stay home for five days after onset of symptoms and limit contact with others in their household.
