Officials say roughly 200 children ages 5-12 who attended a day camp at a suburban Detroit gym may have been exposed to bacterial meningitis from an infected worker.

George Miller, director of Oakland County Department of Health and Human Services, held a news conference Wednesday to discuss the response. He says officials are notifying parents of those who attended the camp between July 1 and 11.

He says they're urging the children be assessed by a doctor. Lifetime Fitness in Rochester Hills notified members by email.

Miller says the employee, a Macomb County adult, is hospitalized.

Meningitis is an infection of the fluid surrounding a person's and the brain. Bacterial meningitis is transmitted through close contact, primarily exchanging saliva. Most people who get the infection recover.
