NASHVILLE, Tenn. (WTVF) — Tennessee's sole Measles case is one of 681 across 22 states this calendar year. That's the highest number of cases in 25 years.
Tennessee officials say the state is fortunate to have just one case, and they're doing everything they can to prevent it from spreading.
That means contacting people who may have come into contact with the disease, but doctors say the best way to stay healthy is to get vaccinated.
Most of the measles cases in this outbreak are in unvaccinated people. The MMR vaccine is safe and 97 percent effective.
