Measles is a highly contagious, vaccine-preventable viral infection. Currently, there is no evidence of ongoing transmission of measles in Maryland.  However, there are ongoing measles outbreaks in areas outside of Maryla​​nd and internationally. On March 20, 2025, the Maryland Department of Health and Prince George's County Health Department announced confirmed cases of measles in two Prince George’s County residents who recently traveled together internationally. These cases are not associated with the recently confirmed measles case in a Howard County resident. More information can be found here​.​

If you think you or your family member have symptoms of measles​, call your doctor before going to the office so staff can take measures to prevent possible spread to other patients.  Do not go to child care, school, work, or out in public if you have symptoms of measles. If you think you or a family member might have been exposed to measles, or if you have questions about vaccinations, contact your healthcare provider.
