Cyclospora Outbreak Sickens Over 400 in Four States

A growing Cyclospora outbreak has sickened over 400 people across four Midwestern states. The U.S. Centers for Disease Control and Prevention (CDC) is investigating the cause. Investigators have not yet identified a specific contaminated food source.

Cases have been reported in Michigan, Ohio, West Virginia, and Kentucky. The CDC, along with state and federal health agencies, is collecting data. They are interviewing sick individuals to determine what foods they consumed before becoming ill. The U.S. Food and Drug Administration (FDA) is also assisting in the investigation.

The CDC is concerned about the increase in cyclosporiasis cases since early May. Several other clusters of illness are under investigation nationwide. The actual number of cases is likely higher than the confirmed total. Some infected individuals may recover without seeking medical care. It can also take several weeks to link a case to an outbreak.

Cyclosporiasis is generally not life-threatening. However, some individuals may experience severe illness requiring hospitalization. Symptoms typically appear about one week after infection. They can persist for days, a month, or longer without treatment. The CDC urges anyone experiencing symptoms to seek medical care promptly.

Public health officials ask diagnosed patients for detailed information about their diet. This helps identify patterns and trace the contaminated food. Healthcare providers should report cyclosporiasis cases to their local health departments. Consumers can reduce risk by learning about foods associated with cyclosporiasis and staying informed about recalls.

The CDC provides guidance for healthcare providers on symptoms, treatment, and patient management. They also offer information on preventing infection. This includes advice on which foods are more likely to be associated with the illness.
