The mumps are making an unwelcome comeback in Maryland, with state health officials confirming a small but noticeable rise in cases this year, centered largely around the Baltimore metro area.
Yesterday, the Maryland Department of Health said there have been 26 mumps illnesses reported so far in 2026. Most of the recent infections have been in adults who live in or around Baltimore. Even so, officials say the overall risk to the general public remains low, pointing to high vaccination rates across the state. State and local health departments are now working together to see whether the cases are connected.
State Numbers and Guidance
According to the Maryland Department of Health, there were 26 total mumps cases in Maryland in 2026, including 19 confirmed and seven probable infections. State officials say they are coordinating with local health departments to track the cases and look for any links among patients.
"The most effective prevention against a mumps infection is to get the Measles, Mumps, and Rubella or MMR vaccine," Deputy Secretary for Public Health Services Dr. Meg Sullivan said in the department’s news release. The agency added that while most people who get mumps recover fully, the illness can lead to serious complications for a small number of patients.
How Mumps Spreads and What to Watch For
Mumps spreads through saliva and respiratory droplets, such as when an infected person coughs, sneezes, or shares drinks, according to the CDC. Symptoms usually develop two to four weeks after someone is exposed.
The classic signs are fever and painful swelling of the salivary glands, known as parotitis. Health officials point out that influenza and other viruses can sometimes cause similar swelling, so laboratory testing is important when clinicians suspect mumps. Most people get better without long-term issues, but complications such as orchitis, meningitis, pancreatitis, or hearing loss can occur and may require prompt medical attention.
Where to Get Vaccinated in Maryland
The MMR vaccine is covered under most insurance plans and is also available for eligible children through the Vaccines for Children program, state officials note. Maryland has expanded free MMR access for uninsured or underinsured adults through the Maryland Vaccine Program.
Residents can reach out to their local health department or check the state’s vaccination clinic information for details on eligibility and appointments, including through the Maryland Vaccine Program and the Baltimore City Health Department. Anyone who develops symptoms that could be mumps is urged to call their health care provider before showing up in person, to avoid exposing others in waiting rooms and clinics.
Local Context
State health officials say the situation is being watched closely as part of routine surveillance for vaccine-preventable diseases. Mumps is not as contagious as measles, they note, but it still deserves attention, especially during a busy respiratory virus season.
