State health officials on Friday confirmed that two Baltimore-area residents have measles, triggering exposure warnings across parts of Anne Arundel and Baltimore counties. Investigators have released a list of supermarkets, medical clinics, and office buildings with specific date-and-time windows and are working to identify people who may have been exposed. Anyone who visited the named locations during the listed hours is urged to monitor for symptoms for 21 days and call a health care provider before going to a clinic or emergency room.
Where and when you could have been exposed
State officials listed possible exposure sites that include Giant Foods in Pasadena, Bean Rush Cafe and Whole Foods in Annapolis, several professional office buildings in Annapolis and Arnold, the Oakwood Professional Building in Glen Burnie, Baltimore Washington Medical Center's emergency department, and Patient First in Pasadena. The full list of addresses, dates, and time windows is detailed by WBAL, which cites the Maryland Department of Health.
Symptoms, risk and post-exposure options
Early measles symptoms include a fever over 101F, runny nose, cough, and red, watery eyes, with a red rash typically appearing one to four days later. Per the Maryland Department of Health, people who have received two doses of an MMR vaccine or who were born before 1957 are generally considered protected, and some people exposed on or after April 14 may qualify for post-exposure treatments such as MMR within 72 hours or immune globulin within six days for high-risk groups. Health officials are asking anyone with symptoms to call their provider first so clinics and emergency departments can take precautions to avoid spreading the virus.
How this fits into a national surge
The local alerts land at a time when measles continues to circulate nationally: the Centers for Disease Control and Prevention reported 1,792 confirmed cases in the U.S. as of April 23, 2026. State officials told local outlets that the two Baltimore-area infections are not known to be connected to the international travel-associated case announced on April 19, as reported by WMAR2News.
What locals should do now
If you were at any of the listed sites during the posted windows and you are not fully vaccinated or are in a high-risk group (infants, pregnant people, or immunocompromised), contact your health care provider or local health department immediately to discuss testing, vaccination, or immune globulin. The Maryland Department of Health asks exposed individuals who develop symptoms to avoid child care, school, and public places and to use phone or telehealth options before seeking in-person care.
