Measles is a highly contagious, vaccine-preventable viral infection. There are ongoing measles outbreaks in areas outside of Maryland and internationally. For more information about measles outbreaks in the United States, see the CDC’s Measles Cases and Outbreaks webpage.
If you think you or your family member has symptoms of measles or might have been exposed to measles, call your healthcare provider before going to a waiting room or emergency department 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 or have been exposed to measles. To check your immunization status, contact your healthcare provider or securely request your records online via My Immunization Record (MyIR). If you have questions about vaccinations, contact your healthcare provider.
