Measles is a reportable disease in Pennsylvania. If you suspect that you or your child have measles and wish to seek care, please call your health care provider, urgent care, or hospital emergency room before leaving home, or contact the Office of Public Health at 610.278.5117 to facilitate a safe visit and reduce exposure for staff and other patients. Health care providers should report suspected cases of measles immediately to OPH at 610.278.5117 or after hours at 610.635.4300.
Individuals are considered to be immune to measles if any of the following applies:
- They were born in 1957 or earlier.
- They have had 2 doses of Measles, Mumps, Rubella (MMR) vaccine.
- They have had measles disease.
The following groups of people are potentially susceptible to measles:
- Infants who are too young to have been immunized (less than one year of age).
- Children who are only partially vaccinated (less than 6 years old).
- Persons who were vaccinated with an inactivated or unknown type of vaccine, which was used from 1963 through 1967, and have not been revaccinated.
- Some persons born after 1957 who have only received one dose of vaccine.
- Those who have refused vaccination
- Those from areas of the world where there is low vaccine coverage or currently circulating measles.
- Immune-compromised persons, such as organ transplant recipients, patients receiving chemotherapy and people living with HIV/AIDS.
Individuals who meet the above criteria or cannot verify their immune status should consult with their primary healthcare provider about the best way to protect themselves from measles.
