Guidance for Individuals Who May Have Been Exposed to Measles
Individuals who may have been exposed to measles and are not immune should contact their healthcare provider or local health department for guidance.
If you have never received a measles-containing vaccine—either the measles, mumps, and rubella (MMR) vaccine or a measles-only vaccine used in some countries—you may be at risk of developing measles.
- If you notice symptoms such as fever, red eyes, runny nose, cough, or a rash that begins on the head and spreads down the body, immediately isolate at home and contact your healthcare provider.
Before visiting a healthcare provider’s office or the emergency room, call ahead to inform them of your possible exposure. This allows staff to coordinate with the health department and take appropriate steps to protect other patients and staff. If in-person care is necessary, wear a mask for the duration of your visit and remove it only if instructed by a healthcare provider.
If you have received two doses of a measles-containing vaccine or were born before 1957, you are considered protected and do not need to take further action. If you have received only one dose, you are still likely to be protected and your risk of infection is low; however, you should contact your healthcare provider about receiving a second dose to ensure full immunity.
Individuals who are immunocompromised or pregnant should consult their healthcare provider for personalized guidance.
