Out of an abundance of caution and consistent with recommendations from the California Department of Public Health, 51³Ô¹ÏºÚÁÏ Davis offers the following public health information:

An individual with a suspected case of mumps was on the Davis campus on the evening of Dec. 3, 2025.

Working in coordination with the Yolo County Health and Human Services Agency, university health officials are conducting contact tracing to identify and notify those who were known to be in close contact with the infected person at a Mondavi Center for Performing Arts event on that date. Through the Mondavi Center, county health officials have reached out to those who sat near the person with a suspected case of mumps. People who were at Latitude restaurant on Dec. 3 between 6 p.m. and 7 p.m. also may have been exposed to mumps.

Mumps is spread through contact with respiratory droplets, so people within a 6-foot radius of the case potentially were exposed and would be considered close contacts. Close contacts should monitor for mumps symptoms, isolate and seek care if they feel sick.

They should consult their healthcare provider if they develop symptoms or have concerns, especially if they are not up to date on the mumps vaccination, are immunocompromised, or are pregnant. In the United States, the mumps vaccine is included as part of the Measles, Mumps and Rubella (MMR) vaccine, and it may be listed that way in a person’s vaccination records.

Because of the University of California immunization policy requiring MMR vaccination (or proof of immunity) for entering students, most of our student population is vaccinated, which decreases the risk of this infection to vaccinated individuals and to our campus community.

According to the Centers for Disease Control and Prevention (CDC),  is a contagious viral infection that can be transmitted through contact with saliva or respiratory droplets spread by coughing, sneezing, talking or sharing drinking containers. It can take two to four weeks from exposure or symptoms to appear. 

Mumps symptoms often start like the flu (fever, headache, muscle aches, tiredness, poor appetite) and then include swollen, tender salivary glands, causing puffy cheeks or jaw and often making it hard to chew or talk. Some infected individuals experience no or minimal symptoms, while others get severe ones like testicular swelling. Pregnant women who become ill with the mumps are at high risk during early pregnancy and should consult with their obstetric provider.

If you are seeking care for symptoms such as these and are unable to address them through a telehealth appointment, please mask when presenting for care. 

There is no specific treatment for mumps, and care is supportive. Most people with mumps recover completely within two weeks of becoming ill.

It is strongly recommended that everyone is up to date on their MMR vaccination series. Receiving the vaccine now will not protect against past exposures, but the vaccine is designed to protect against future exposures to mumps, measles and rubella.
