Measles 101: What you need to know

Measles (Rubeola) is an extremely contagious disease that can cause death or lead to serious long-term health complications, especially in children younger than 5 years of age.

  • Measles spreads easily through the air, often from an infected person’s cough or sneeze.
  • The virus can live for up to two hours in the air after an infected person leaves an area.
  • Symptoms (fever, cough runny nose, watery eyes, and rash) usually appear within 7 to 14 days of exposure, but may take as long as 21 days to become evident.

Your measles questions, answered

What are the symptoms of measles?

Measles symptoms typically appear 7 to 14 days after contact with the virus. The first symptom is a high fever (which may spike to more than 104°F), with dry cough, runny nose (coryza), and red, watery and swollen eyes (conjunctivitis or pinkeye). The measles rash develops 3-5 days later. It starts on the head with red, flat or raised spots that spread down the body. It is generally not itchy.

Who is immune to measles?

Three groups of people are considered immune to measles: those who have had two documented doses of the measles, mumps, and rubella (MMR) vaccine in their lifetime, a prior lab-confirmed case of measles, or were born before 1957 (when measles was so common that everyone was considered exposed). 

I know I'm fully vaccinated, but can I get my titers checked, just in case?

Titer checks on fully-vaccinated individuals is not clinically recommended. Here's why: Our immune systems have memory cells that allow antibodies to remain at low levels until they're needed. Low levels of MMR antibody titers do not mean low levels of protection against the measles. Exceptions apply to those who may be immunocompromised. 

I know I’m vaccinated but can I get an additional dose of MMR?

It depends. Here are the situations where an additional MMR dose is recommended:

  • You have received 1 dose of MMR but are traveling internationally,  work in health care, live in a measles outbreak area, or are a household contact of someone who is immunocompromised.
  • You were born between 1957 and 1968. People in this age group may have received an ineffective measles vaccine and should get 1 additional MMR dose.

If I've had measles can I get it again?

No, you can't get measles again if you have had a prior, documented, lab-confirmed case.

I've been exposed to measles and I'm not vaccinated. What should I do?

For most people, the only way to prevent measles or reduce the severity of measles infection is to get the MMR (measles, mumps, and rubella) vaccine within 72 hours of the exposure. The MMR vaccine is available at all AHN primary care, pediatric and Express Care locations. The exception is that pregnant women and severely immunocompromised people cannot receive the MMR vaccine and can be referred by their doctor for a medicine called IVIG within 6 days of the exposure.

What if my baby is exposed to measles before they're old enough to get vaccinated?

Infants younger than 6 months of age are too young to receive the MMR vaccine. If your baby has been exposed to measles, contact your pediatrician, family physician or one of our AHN Express Care locations as soon as possible. A medicine called intramuscular immunoglobulin (IMIG) can be given to infants younger than 6 months within 6 days of the exposure to help prevent measles. 

My baby is under 12 months. How can I help protect them?

In areas where measles is spreading, new guidelines recommend that babies get an MMR vaccine starting at 6 months, (not the usual 12 months). Contact your family doctor or pediatrician for details.
