Parasite Infections In Illinois: Over 200, With 18 Hospitalized

A fast-growing outbreak of a nasty intestinal illness has now pushed Illinois past the 200-case mark, while neighboring Michigan continues to lead the nation with over 3,300 infections.

According to the Illinois Department of Public Health, Illinois has now confirmed 216 cases of cyclosporiasis, with 18 hospitalizations reported so far.

That's a sharp jump from just a week ago, and health officials say the investigation is still underway. Michigan has been hit especially hard, with literally thousands of reported cases, making it the epicenter of the national outbreak.

So, What Exactly Is This Hard To Pronounce Bug That Give You Explosive Diarrhea?

Cyclosporiasis is caused by the microscopic parasite Cyclospora cayetanensis. It usually spreads when people eat fresh produce or drink water contaminated with the parasite.

Symptoms often begin about a week after exposure and can include severe watery or "explosive" diarrhea, stomach cramps, nausea, fatigue, bloating and weight loss. Without treatment, symptoms can linger for weeks or even come and go for a month or longer. The good news is that it's rarely fatal.

Investigators have not identified a single source yet, but lettuce and other salad greens have emerged as leading suspects. Officials stress that no specific grower, supplier or type of lettuce has been confirmed, and other foods remain under investigation.

Reports that Taco Bell may be connected are also unconfirmed. The company says it has voluntarily removed some fresh produce ingredients from certain restaurants while health officials continue their investigation.

Here's What You Can Do

Experts recommend washing fresh fruits and vegetables thoroughly under running water, even if they're labeled "pre-washed." Buying whole heads of lettuce instead of bagged greens may reduce handling, and peeling produce when possible can help.

Since heat kills the parasite, cooking vegetables is the safest option whenever practical. You're also safe with the frozen varieties.

If you develop persistent diarrhea after eating fresh produce, contact your healthcare provider, as cyclosporiasis is treatable with prescription antibiotics.

The good news is that health officials are closing in on the source. Until they do, however, it may be wise to give your salad an extra rinse, or consider cooked vegetables for a little while.
