Maryland reports 26 mumps cases in 2026 as officials stress low public risk statewide

An early-year rise, concentrated in the Baltimore region

Maryland health officials have confirmed an increase in mumps cases statewide, reporting 26 cases so far in 2026 as of February 19. The total includes 19 confirmed cases and seven probable cases, and most infections have occurred among adults in the Baltimore metropolitan area. Officials emphasized that the overall risk to the general public remains low, citing Maryland’s high vaccination coverage.

Public health authorities said they are working with local health departments to determine whether the cases share a common exposure. As of the most recent update, investigators had not identified a single link connecting the reported infections.

What mumps is and how it spreads

Mumps is a vaccine-preventable viral illness that spreads primarily through direct contact with saliva or through respiratory droplets. Symptoms typically develop about two to four weeks after exposure. While mumps can affect people of any age, adults may face a higher risk of certain complications.

The most recognizable symptom is parotitis, a painful swelling of salivary glands on one or both sides of the face. Fever is also common. Health officials noted that parotitis can also be caused by other circulating respiratory viruses, including influenza, which can complicate initial clinical assessment and increase the importance of appropriate medical evaluation and testing when warranted.

Vaccination guidance and outbreak response

Officials reiterated that the most effective prevention is the measles, mumps and rubella (MMR) vaccine. Routine childhood vaccination consists of a two-dose series, with the first dose recommended at 12–15 months and the second at 4–6 years. Health officials urged residents to review immunization records and consult health care providers about whether they are up to date.

The vaccine is generally covered by health insurance and is available to eligible children through the Vaccines for Children program. Adults who are uninsured or underinsured were advised to contact their local health department regarding access to no-cost vaccination options through state programs.

Symptoms, care, and when to seek help

There is no specific antiviral treatment for mumps; care is focused on symptom relief, including management of fever and pain. Most patients recover fully. However, health officials warned that serious complications can occur and may require urgent medical attention.

• Inflammation of the testicles, ovaries, or breasts
• Pancreatitis
• Hearing loss
• Meningitis
• Encephalitis

Officials advised anyone who develops symptoms consistent with mumps to contact a health care provider or local health department promptly for evaluation and potential testing.

As case investigations continue, health officials are focusing on vaccination status, exposure history, and potential connections among adult cases in the Baltimore area while maintaining that statewide risk remains low.
