If you were there – monitor for symptoms and check to be sure your MMR vaccinations are up to date.  Measles is a highly contagious illness that can spread easily through the air when an infected person breathes, coughs or sneezes. The virus can stay in the air for 2 hours after a person with measles leaves the space. It is so contagious that about 9 out of 10 people who come near a person with measles will also become infected if they are not vaccinated.

Measles symptoms usually appear in two stages. In the first stage, most people have a fever greater than 101 degrees, a runny nose, watery red eyes, and a cough. These symptoms usually start 7 to 14 days after exposure. The second stage starts 3 to 5 days after the symptoms begin, when a rash begins to appear on the face and spreads to the rest of the body. People with measles are contagious from 4 days before the rash appears through 4 days after the rash appears.

Maryland officials say there is no known connection between this case and previous cases reported by the Maryland Department of Health in 2026.
