School officials at Amity Regional High School in Woodbridge have warned students and staff about possible exposure to the mumps.

Amity's superintendent sent out a letter to the school community Thursday, saying they may have been exposed during the week of Dec. 4. The Health Department confirms one person who has the mumps was in the building during that time.

Health officials say they notified the school not to scare anyone, but to make people aware of the case and ask them to monitor for symptoms that include swollen salivary glands, fever, headaches and body aches.

Mumps can be prevented with the MMR vaccine. Schools in Connecticut require it for students, but there are medical and religious exceptions. Health officials say it's 88 percent effective.

Health officials are asking people to monitor for signs and symptoms of mumps through Dec. 29 and that if they develop, go to their doctor. That exposure timeline could extend if another case develops.

Mumps is a contagious viral disease that's usually transmitted through coughing, sneezing or saliva.
