Measles FAQ
What is Measles?
Measles is a highly contagious viral illness caused by the rubeola virus. It spreads through the air when an infected person breathes, coughs, or sneezes. The virus can remain active in the air or on surfaces for up to two hours after an infected person leaves the area.
What are the Symptoms?
Symptoms typically appear 7–14 days after exposure and often include:
- High fever (100.4°F or higher)
- Red, watery eyes (conjunctivitis)
- Dry cough
- Runny nose
On days 3-5 after initial symptoms, a rash develops on the face, neck or chest and spreads downward to the rest of the body.
If you suspect or notice symptoms of measles, DO NOT go directly to a clinic, urgent care, or emergency room without calling first. Calling ahead helps prevent potential exposure to others.
How Does Measles Spread?
Measles spreads easily through the air when an infected person coughs, sneezes, or breathes. It is so contagious that if one person has it, up to 9 out of 10 unvaccinated people nearby may become infected.
The virus can remain infectious in the air and on surfaces for up to two hours after exposure.
Who Is at Highest Risk for Severe Illness?
Individuals at higher risk include:
- People who are immunocompromised (individuals on immunosuppressive medications, biologics, chronic steroids, chemo, etc.)
- Infants under 12 months of age
- Pregnant individuals
- Individuals with underlying medical conditions
How Can I Protect Myself?
According to the CDC, the best protection against measles is the Measles, Mumps, and Rubella (MMR) vaccine.
- Two doses of MMR vaccine are approximately 97% effective at preventing measles.
- The MMR vaccine is safe and widely used.
