The Philadelphia Department of Public Health is working with Montgomery County Department of Health and Human Services and the Pennsylvania Department of Health to identify people who may have been exposed to a confirmed measles case in an unvaccinated child from Montgomery County.

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.

Why measles is dangerous: Key facts

Did you know? Measles is one of the most contagious diseases in the world. Here’s why:

• 9 out of 10 people who aren’t protected and are exposed to measles can get sick.
• 1 in 5 unvaccinated people in the U.S. who gets measles are hospitalized.
• Measles complications can be severe, especially for children:
  • 1 out of 20 children with measles gets pneumonia, which is the most common cause of death from measles in young children.
  • About 1 out of 1,000 children with measles develops brain swelling.
  • Pregnant people who aren’t vaccinated are at higher risk for preterm birth or low-birth-weight babies.
  • Even with the best care, 1 to 3 out of 1,000 children with measles will die from severe illness.

Measles can affect anyone who isn’t immune to the disease, but it is especially dangerous for babies who are too young to get the measles vaccine and young kids who haven’t received the vaccine. While at least 93% of children in Philadelphia are vaccinated by age 6, more cases of measles in the region puts our communities at risk.

The good news? Measles is preventable with the MMR vaccine!

The MMR vaccine (measles, mumps, rubella) is 97% effective at preventing measles when two doses are given.

Did you know? Before the vaccine became widely available, measles outbreaks would kill over 2.6 million people each year around the world. MMR vaccine has been safely used for decades and saves lives.

If you or your child need vaccination, now is the time to get protected.

Who should get a measles vaccine?

 Children:

• 1^st dose: 12–15 months old
• 2^nd dose: 4–6 years old

 Adults:

• Born before 1957? You’re likely immune and don’t need another vaccine dose.
• Vaccinated between 1963 and 1968? If you received the inactivated vaccine or aren’t sure which vaccine type you received, you’ll need another dose.
• Received only one dose? A second dose may be needed, especially if you are entering college or another higher education program, or live with someone who has a weakened immune system.

 If you’re traveling internationally:

The following groups should receive a vaccine dose at least 2 weeks before travel:

• Infants who are 6-12 months old
• Children at least 1 year old who haven’t received their second dose
• Adults with only one dose and no test results that show they’re immune to measles

What to do if you were exposed to measles

If you’re immune:

No action is needed. You’re considered immune if you:

• Were born before 1957.
• Have documentation of past measles infection.
• Have received two doses of MMR vaccine and don’t have a weakened immune system.

If you received one dose of MMR vaccine and were exposed, you may need a second dose. Call your healthcare provider right away to check your immunity.

If you’re NOT immune:

Take immediate action. This includes babies, who usually aren’t vaccinated yet:

• Call your healthcare provider or pediatrician ASAP
  • Before you go see them, tell them about your measles exposure.
  • You may qualify for post-exposure treatment, which can help prevent measles.
  • Tell them if you or your exposed child doesn’t feel well.
  • Ask them to call the health department.
• Stay home. Avoid contact with others, especially if they’re unvaccinated or have a weakened immune system.
• Monitor your symptoms for 21 days after exposure.

If you’re not sure about your immunity:

• Call your healthcare provider or pediatrician ASAP.
  • They can check your vaccine records or, if needed, order a simple blood test to confirm your immunity.
  • Tell them if you or your exposed child doesn’t feel well.
• Wear a mask in indoor public spaces and around anyone who is unvaccinated until you confirm your status.

Symptoms of measles

Measles symptoms usually appear 7-14 days after exposure and develop in stages:

Early symptoms

• High fever
• Cough
• Runny nose
• Red, watery eyes

Later symptoms (Days 2-5)

• Tiny white spots inside the mouth (Koplik spots)
• Measles rash, which usually starts as flat spots on the face, then spreads down the body
• High fever that spikes when the rash appears

Rash on different skin tones

• On lighter skin, the rash can appear red
• On darker skin, it may look purple or darker than surrounding skin

Final takeaways – What you need to do

• Check if you were exposed.
• Get vaccinated if you haven’t already.
• If you’re exposed and not immune, stay home & call your doctor.
• Know the symptoms and act fast if you feel sick.

Measles is highly contagious, but completely preventable with vaccination. Don’t wait – check your status today!
