Here’s what you need to know about measles:
Signs and symptoms of measles
The first symptoms of measles usually show up seven to 14 days after exposure, but they can take as long as 21 days to appear.
Symptoms include:
- High fever (may spike to over 104˚F).
- Cough.
- Runny nose.
- Red, watery eyes (conjunctivitis).
Two to three days after the initial symptoms begin, Koplik spots may appear inside the mouth. These are tiny white spots that show up on the inner cheeks, gums, and roof of the mouth.
Three to five days after symptoms begin, the measles rash may appear. This is a rash that is red, raised, and blotchy. It usually starts on the face and spreads to the rest of the body.
If you believe you have measles, you should call your doctor or emergency room so they can prepare and avoid exposing others to the virus.
How effective is the measles vaccine?
Health officials said the vaccine is very safe and highly effective.
According to the CDC, two doses of the measles vaccine are about 97% effective at preventing measles if you’re exposed to the virus. One dose of the vaccine is believed to be about 93% effective. You are considered fully protected about two to three weeks after getting the vaccine.
If you are unvaccinated and exposed to the virus, health officials say getting the measles vaccine within 72 hours of exposure can help reduce your risk of developing measles.
Some people with weakened immune systems may not be able to get the vaccine.
“Getting vaccinated is the best way to protect ourselves and our loved ones from potential outbreaks of diseases like measles,” said Dr. Natasha Bagdasarian, chief medical executive. “It is important to make sure our families are up to date on all routine vaccines to prevent the spread of severe illness and disease. Now is a great time to check with your health care provider to make sure you are current with all your vaccines.”
2019 Michigan measles outbreak
In 2019, there were at least 46 confirmed measles cases in Michigan.
That year there were 1,274 measles cases across 31 states, according to the CDC.
That was the greatest number of cases reported in the U.S. since 1992. The majority of cases were among people who were not vaccinated against measles.
To give that number some perspective, there were 375 cases in 2018, and 13 cases in 2020.
