The Michigan Department of Health and Human Services and St. Clair County Health Department have confirmed two probable cases of mumps in adults who traveled internationally to India and became ill after their return in early March. The third probable case is a student at Fort Gratiot Middle School in Port Huron. Mumps is a vaccine-preventable disease that is spread through saliva or mucus from the mouth, nose or throat, usually when the person coughs, sneezes or talks. Symptoms of mumps usually begin 16-18 days after exposure, but can appear up to 25 days after exposure. Symptoms may include fever, headache, muscle aches, tiredness, loss of appetite and swollen tender glands under the ears on one or both sides.
