Maryland Health officials have been notified of a confirmed case of measles in a person who traveled through Maryland while infectious late on January 7^th through early January 8^th. Officials say anyone who may have shared several public conveyances during those dates and hours may have been exposed.

What to Do If You Think You May Have Been Exposed 

• Find out if you have been vaccinated for measles or have had measles previously. If you have received two doses of a measles-containing vaccine, or were born before 1957, you are generally considered protected. 

  • To check your immunization status, call your healthcare provider or request records securely online via My Immunization Record “MyIR”.

• If you are not fully vaccinated or otherwise immune to measles and you might have been exposed, call your healthcare provider or your local health department to discuss the best next steps for you.

• Monitor yourself for any early signs of measles for 21 days after your potential exposure.

• If you develop a fever or other symptoms of measles, stay home and do not go to childcare, school, or work, or other public spaces, and contact your health care provider. Call your health care provider before showing up at a waiting room or emergency department so that the facility can take measures to prevent measles from spreading to others.

Early symptoms of measles are a fever of more than 101 degrees Fahrenheit, runny nose, cough, and red, watery eyes. Usually, one to four days after the early symptoms, a red rash appears on the face and spreads to the rest of the body. Symptoms typically develop 10 to 14 days after exposure but can develop as soon as seven days and as long as 21 days after exposure. A person with measles is contagious, beginning four days before the rash appears until four days after the rash begins. 

“Vaccination remains essential to protecting ourselves, our families, and our communities against measles and other infectious diseases,” said Maryland Department of Health Deputy Secretary for Public Health Services Dr. Meg Sullivan. “These types of situations underscore the importance of knowing your vaccination status and ensuring you are up to date with all recommended vaccines.”

Measles cases occur sporadically in Maryland. There have been no cases of measles in 2026, three cases identified in 2025, one in 2024, one in 2023, and no cases from 2020-2022.
