Tennessee has reported four confirmed cases of measles, and health experts are encouraging families to stay informed and take simple, effective steps to protect their children. Although measles was eliminated in the U.S. in 2020, cases are beginning to rise again, largely due to a drop in vaccination rates.
As of March 27, there were about 500 measles cases reported across 18 states, with two confirmed deaths and one more under investigation. While this may sound alarming, it’s important to remember that we have a powerful tool to prevent measles: vaccination.
Measles spreads very easily among people who are not vaccinated. However, communities with strong vaccination rates are seeing much slower transmission, thanks to herd immunity. Unfortunately, as more children go unvaccinated, the chance of measles spreading — especially in school settings — grows.
Most school districts in Tennessee require the MMR (measles, mumps, and rubella) vaccine, which offers excellent protection. But with vaccine hesitancy increasing, experts are keeping a close eye on the potential for outbreaks among kids.
Dr. Joseph Gigante of Monroe Carell Jr. Children’s Hospital at Vanderbilt notes that the current measles cases likely stem from the outbreak in West Texas. “It’s something we’re watching very closely,” he said.
Vaccination: The Best Protection
The measles vaccine is safe, effective, and widely available. Since measles is one of the most contagious viruses — spreading through the air when someone talks, coughs, or sneezes — vaccination is the best way to protect yourself and your loved ones. About 90 percent of unvaccinated people exposed to measles will get sick.
“It’s so easy to prevent,” said Dr. Gigante. “The best thing parents can do is make sure their children are vaccinated.”
Recognizing Measles Symptoms
If you’re wondering what to look out for, common symptoms include:
-
High fever (102–103°F)
-
Rash
-
Small white spots in the mouth (Koplik spots)
-
Runny nose
-
Scratchy throat
-
Dry cough
People are contagious up to four days before the rash appears and typically remain contagious four to five days after. Symptoms usually show up 7 to 14 days after exposure but can take as long as 21 days—meaning exposed children may need to quarantine for up to three weeks, which can be challenging for working parents.
In rare cases, measles can lead to serious complications like pneumonia, brain swelling (encephalitis), or even a rare and fatal neurological condition called subacute sclerosing panencephalitis (SSPE), which can appear months or years after infection.
Bottom Line
Measles is preventable, and the MMR vaccine is the best defense. Talk to your doctor if you have questions or concerns about vaccination — it’s a simple step that can make a big difference for your child’s health and for your community.
