What is Measles?
Measles is a highly contagious respiratory disease that causes a rash and fever. It can cause serious health complications, including pneumonia and encephalitis (swelling of the brain). The best way to protect yourself is to make sure you are vaccinated against Measles.
How does Measles spread?
Measles spreads easily through the air when an infected person coughs or sneezes. You can catch the disease by breathing in the virus or by touching an infected surface and then touching your eyes, nose, or mouth. Measles is highly contagious and can remain for up to two hours in a room where an infected person was.
What are the symptoms of Measles?
Symptoms will start to appear between 7-14 days after exposure, and sometimes up to 21 days after exposure. Symptoms typically include:
- High fever (may spike to over 104°)
- Cough
- Runny nose
- Red, watery eyes
About 3-5 days after symptoms begin, a rash will occur. Typical traits of the rash are:
- Usually begins as flat, red spots that appear on the face at the hairline and spread down to the neck, arms, legs, and feet
- Small, raised bumps may also appear on top of the flat, red spots
A person with Measles can spread the virus to others from four days before the rash appears through the fourth day after the rash appears.
What can you do to stay safe?
Getting the Measles vaccine (MMR) is the best way to prevent measles. The MMR vaccine is extremely effective and safe. Two doses of the vaccine are 97% effective at preventing Measles.
If you are unsure if you were vaccinated for Measles, call your health care provider or the Seneca County Health Department at (315) 539-1920 to check your vaccination record.
