Frequently Asked Questions
Why is measles so contagious?
Measles can stay in the air for two hours after a person with measles leaves the space. This increases the likelihood for others to be exposed and become ill.
What health complications are associate with measles?
Children younger than five years old, adults over age 20, pregnant women and those with weakened immune systems are more likely to experience complications. Common complications include ear infections and diarrhea; however, severe health problems like pneumonia, swelling of the brain and even death can occur.
When do measles symptoms appear?
Symptoms typically appear 7 to 14 days after exposure. First symptoms usually include fever, cough, runny nose, and red/watery eyes. Tiny white spots in the mouth may follow those symptoms. A rash of small, raised bumps typically appears 2 to 4 days after symptoms begin. The rash generally lasts 5 to 6 days.
How long is a person with measles contagious?
The virus is contagious four days before the rash appears through four full days afterwards (creating at least a nine-day infection period).
If I think I have been exposed, what should I do?
If you suspect exposure, you should isolate to prevent potential spread to others and call your doctor. If you do not have a health care provider, contact your local health department for next steps.
