 •  Check your vaccination records. Individuals are usually protected from measles if: 

You were born in 1957 or earlier, or you have had 2 doses of Measles, Mumps, Rubella (MMR) vaccine, or the recommended vaccine doses based on your age. 

Laboratory testing confirming of disease or immunity.

 •  If you are not fully vaccinated or protected and think you might have been exposed, call your health care provider or the Office of Public Health for further instructions.  

 •  Watch for symptoms for 21 days after exposure, including fever, an unexplained rash, cough, congestion or runny nose, or red watery eyes (conjunctivitis).  

 •  If you develop symptoms, stay home and call a health care provider right away. 

 •  Call your health care provider, urgent care, or hospital before you visit. This helps protect staff and other patients. 

Health officials said those most at risk for complications are infants and children less than 5 years old, pregnant women, and people with weakened immune systems, such as those with leukemia and HIV infection.
