Two Measles Cases Confirmed in Maryland; Multiple Exposure Sites Identified in Anne Arundel County

The Maryland Department of Health (MDH) has confirmed two cases of measles in Maryland residents in the Baltimore metropolitan area, prompting health officials to issue a public advisory and identify multiple potential exposure locations across Anne Arundel County.

According to MDH, both individuals recently traveled to an area within the United States experiencing active measles transmission. The exact source of exposure remains unknown, and officials say there is no known connection between these cases and a previously reported travel-related case announced on April 19, 2026.

Health officials are actively working to identify and notify individuals who may have come into contact with the infected residents.

Potential Exposure Locations

Residents who were at the following locations during the listed dates and times may have been exposed:

Giant Foods Pasadena — April 12, 10 a.m. to 1 p.m.

Bean Rush Cafe — April 14, 8:30 a.m. to 11:30 a.m.

What Residents Should Do

MDH advises anyone who may have been exposed to first verify their vaccination status. Individuals who have received two doses of a measles-containing vaccine, or who were born before 1957, are generally considered protected.

Those who were at any of the listed locations and are not fully vaccinated or otherwise immune should monitor for symptoms for up to 21 days after exposure. Early symptoms include fever over 101°F, runny nose, cough, and red, watery eyes, followed by a rash that typically begins on the face and spreads.

Anyone who develops symptoms is urged to stay home and contact a healthcare provider before visiting a medical facility to help prevent further spread.

Individuals potentially exposed on or after April 18 may also be eligible for post-exposure treatment and should contact their healthcare provider or local health department promptly.

Highly Contagious Virus

Measles is a highly contagious airborne disease that can linger in the air for up to two hours after an infected person leaves an area. It can also spread through direct contact or by touching contaminated surfaces.

A person with measles is contagious from four days before the rash appears until four days after its onset.

“Vaccination remains essential to protecting ourselves, our families, and our communities against measles and other infectious diseases,” said Dr. Meg Sullivan, Deputy Secretary for Public Health Services. “Talk with your healthcare provider to ensure you and your family are up to date with all recommended vaccines, including the MMR vaccine.”

Vaccination and Case History

The MMR (measles, mumps, and rubella) vaccine is routinely administered in two doses—first at 12 to 15 months and again at 4 to 6 years old. In some cases, infants traveling to high-risk areas may receive an early dose.

The vaccine is typically covered by insurance and is also available through programs such as the Vaccines for Children Program and the Maryland Vaccine Program for eligible uninsured or underinsured adults.

Measles cases remain relatively rare in Maryland. State data shows three cases in 2025, one case each in 2024 and 2023, and none between 2020 and 2022. Prior to the newly announced cases, one additional case had been confirmed in 2026 involving international travel.

MDH officials said no further details about the individuals will be released to protect their privacy.
