Measl​​es

Updated October 29, 2026 

Measles is a highly contagious, vaccine-preventable viral illness that causes a high fever with a full-body rash. Measles infection can affect the body's respiratory, immune, and central nervous systems. The best way to protect yourself, your family, and your community from measles is to get vaccinated.​

The Maryland Department of Health is working with Maryland local health departments and healthcare providers to respond to an outbreak of measles among unvaccinated individuals; however, there is currently no evidence of widespread community transmission. For more information about measles outbreaks in other areas of the United States, see the John Hopkins Bloomberg School of Public Health measles tracker. 

For instances in which MDH is aware of possible public exposure from a measles case, that information is shared through pre​ss releases.
