Daviess County health officials have confirmed one lab-tested case of measles.
County Health Officer Dr. Merle Holsopple says measles is highly contagious and spreads through the air.
The virus can linger for up to two hours after an infected person leaves.
People who aren’t vaccinated are at risk, while the MMR vaccine protects against it.
Symptoms include cough, high fever, runny nose, red or watery eyes and a rash.
If you’re unvaccinated and have symptoms, stay home until four days after the rash starts.
If you want testing, call your health care provider first.
Officials say don’t walk into a clinic or ER without calling ahead.
