On Feb. 23, the Indiana Department of Health (IDOH) was notified of a confirmed case of measles in an Indiana resident -- the first confirmed case in the Hoosier State since 2019. Clinicians should be vigilant for additional cases of measles and immediately report suspected cases of measles to the IDOH. 

Measles is a highly contagious respiratory disease caused by a virus. It is rare in the United States due to the widespread availability of the measles, mumps and rubella (MMR) vaccine. However, visitors from other countries or U.S. citizens traveling abroad can become infected, particularly before or during travel.
 
More than 93% of people who receive a single dose of MMR will develop immunity to measles, and more than 97% will be protected after receiving a second dose. Two doses of the vaccine are needed to be fully protected. Individuals born before 1957 are presumed to be immune to measles.
 
As of Feb. 15, the Centers for Disease Control and Prevention (CDC) reported 20 confirmed measles cases in the U.S. this year.

Details on measles reporting, laboratory testing, infection control, clinical guidance and additional resources are included in the attached Indiana Health Alert Notification, which can be read here.
