Measles Public Information Update

April 24, 2025


What is Measles? 
Measles is a highly contagious and potentially deadly viral disease. If one person has it, 9 out of 10 unprotected people nearby can catch it too. 
How Does Measles Spread? 
Measles spreads through: 
 Tiny drops in the air when someone with measles coughs or sneezes 
 Touching the same surfaces as someone with measles 
 Direct contact with sick people 
The virus can stay active in the air or on surfaces for up to 2 hours. 
Timeline of Measles 
 Catching the Virus: It usually takes 7-14 days after exposure before you feel sick 
 First Signs: Fever, cough, runny nose, red eyes, feeling unwell 
 Rash Appears: 3-5 days after first signs, a red rash starts at the hairline and moves down the body 
Signs of Measles 
 High fever (often over 104°F) 
 Cough 
 Runny nose 
 Red, watery eyes 
 Small white spots in the mouth 
 Red, spotty rash that starts at the hairline and spreads down 
Not everyone will have all these signs, but they might still spread measles to others. 
Protecting Your Community 
Staying home if you think you have measles helps protect everyone. Even if you don't feel very sick, measles can be deadly for babies, pregnant women, and people with weak immune systems. By staying home and getting tested, you keep your neighbors and family safe. 
What To Do If You Think You Have Measles 
If you think you have measles or were near someone with measles: 
 Stay home 
 Call your doctor before going in 
 Tell them you might have measles 
 Ask how to visit safely without spreading the virus 
Vaccine Information 
The MMR shot is the best way to prevent measles. Sometimes people who got the shot can still get measles, but they usually don't get as sick and are less likely to spread it to others. 
"For those unvaccinated or those unsure of their vaccination status, now is the time to review records and get caught up if needed," said Dr. George Turabelidze, state epidemiologist with DHSS. 
When to Call a Doctor 
Call your doctor if you or your child: 
 Were near someone with measles 
 Show signs of measles 
 Need to check if your shots are up to date
