What is Mumps?

Mumps is a contagious disease caused by a virus. It spreads through saliva or mucus from the mouth, nose, or throat. An infected person can spread the virus by:

  • coughing, sneezing, or talking,
  • sharing items, such as cups or eating utensils, with others, and
  • touching objects or surfaces with unwashed hands that are then touched by others.

Mumps likely spreads before the salivary glands begin to swell and up to five days after the swelling begins.

CDC Recommendation

CDC recommends children get two doses of MMR vaccine: the first dose at 12 through 15 months of age, and the second dose at 4 through 6 years of age. MMR vaccine is very safe and effective. Teens and adults, check with your healthcare provider to make sure your immunizations are up to date.


Barrington 220 School District is currently experiencing an outbreak of mumps in several schools. The district has 12 schools in three counties.


CCDPH is actively investigating suspected cases of mumps and providing recommendations to schools in our jurisdiction that have cases.

We are working closely with our colleagues in other public health jurisdictions and with the Illinois Department of Public Health (IDPH). We have provided guidance to administrators at Barrington 220 School District to prevent further spread of mumps. Our guidance focuses on recommendations for students, faculty and staff; especially those who may be susceptible. For mumps case counts, please visit the Illinois Department of Public Health website.


  • Make sure your vaccinations are up to date.
  • Talk to your healthcare provider if you are not sure your vaccination is up to date.
  • If you’re unsure of your immunity, ask your healthcare provider for a blood test (a titer) to determine proof of immunity.
  • Keep documentation from your health care provider if you've had mumps disease.
  • Keep your vaccination records or proof of immunity in a safe place.
