Ohio cyclosporiasis cases top 1,200

Catch up quick: Federal health officials attribute the "explosive diarrhea" outbreak to contaminated shredded lettuce served at Taco Bell in five states, including Ohio.

• A Cleveland-area man has filed a lawsuit against one store.
• News reports link the lettuce to supplier Taylor Farms.

Threat level: Cyclosporiasis doesn't spread from person-to-person or "'run its course' the way a stomach bug typically does," HealthTrack chief medical officer Steven Goldberg tells Axios. Symptoms may improve and then return.

• "This is not a 'wait it out' illness."

If you suspect you have it, ask a health care provider to order a specific stool test to confirm, the Ohio Department of Health tells Axios. Routine tests don't include it.

• The illness is "highly treatable with antibiotics," but "delaying diagnosis and treatment could result in dehydration and related complications."

What's next: The department's dashboard is updated each Thursday afternoon.
