The Philadelphia Department of Public Health is working closely with local and state public health agencies and local health care systems to respond to any confirmed measles cases in the region.

If you were in any of the locations below during the listed times, check to see if you’re immune to measles and watch for symptoms.

You can also request your vaccine records today so you know if you’re immune in case you’re around someone with measles in the future. Request them here.

Where & when was the exposure?

Philadelphia County

  • Pennsylvania Hospital Emergency Department
    • April 6 between 3:55 pm and 11:20 pm

Montgomery County

  • Holy Redeemer Hospital Emergency Department
    • April 8 between 6:05 pm and 9:45 pm

What to do if you were exposed to measles

If you’re immune

No action is needed. You’re considered immune if you don’t have a weakened immune system and meet one of the following:

  • Received two doses of MMR vaccine.
  • Were born before 1957.
  • Have documentation of a past measles infection.

Received just one dose of MMR vaccine? You’re still protected against measles and usually don’t need to stay home away from others (also called quarantine) after an exposure. However, you may need a second vaccine dose. Contact your healthcare provider or pediatrician ASAP to find out more.

If you’re not immune

Take immediate action, especially if your infant is less than 1 year old, you’re pregnant, or you have a weakened immune system.

  • Call your healthcare provider or pediatrician ASAP
  • You may qualify for post-exposure treatment, which can help prevent measles.
  • Ask them to call the health department.
  • Stay home (quarantine) and monitor your symptoms for 21 days after exposure. Avoid contact with others, especially if they’re unvaccinated or have a weakened immune system.
  • If you or your child feel sick especially if you have fever and/or rash, call ahead before visiting the clinic or hospital. Because measles spreads easily, special steps may be needed to protect others.

There are specific quarantine recommendations for exposure locations:

    • People who are not immune and were at:
      • Pennsylvania Hospital Emergency Department on April 6 between 3:55 pm and 11:20 pm should quarantine until Sunday, April 27.
      • Holy Redeemer Hospital Emergency Department on April 8 between 6:05 pm and 9:45 pm should quarantine until Tuesday, April 29.

If you’re not sure if you’re immune

  • Ask your healthcare provider or pediatrician to check your vaccine records.
  • Your provider can confirm your status or order a simple blood test to check for immunity.
  • Also, tell them if you or your child feel sick, especially if you have fever and/or rash.
  • Stay home until you confirm your status. If you must be around others, wear a mask in indoor public spaces and around unvaccinated people until you verify your immunity.
