DETROIT, MI -- State health leaders say there could be a rubella exposure risk for those who attended the North American International Auto Show in Detroit.

A person from another state was at the auto show from Jan. 13-15 and later was diagnosed with rubella, also known as the German measles, according to the Michigan Department of Health and Human Services.

That person may have been contagious while in Detroit, health officials say.

Rubella is described as “a viral illness and its symptoms can include a low-grade fever, sore throat and a rash that starts on the face and spreads to the rest of the body.”

Symptoms usually show up from 12 to 23 days after exposure.

People who may have been exposed and are unsure of their vaccination status should contact their doctor with any questions. Michigan’s last case of rubella was in 2007.
