The US Centers for Disease Control and Prevention (CDC) announced a rapid increase in cyclosporiasis cases across the country. The intestinal infection caused by a microscopic parasite has affected more than 18,000 people in 45 states.

According to CDC data, 6,707 locally acquired laboratory-confirmed cases have been recorded since May. Of these, 423 were hospitalized for treatment. Additionally, more than 11,500 suspected cases are pending further analysis for confirmation in the system.

Lettuce-linked transmission detected in 9 states

According to reports in the US media, cases in some states were linked to chopped iceberg lettuce used in restaurants. Investigations point to unhygienic processing practices, especially for raw vegetables. In total, traces of lettuce-borne transmission were found in 9 states.

How is the disease transmitted?

Cyclosporiasis is defined as an intestinal infection caused by the Cyclospora parasite. The disease is transmitted by eating raw food that has come into contact with contaminated water or human feces, and it primarily manifests as severe diarrhea.

Officials are warning the public to thoroughly wash raw vegetables and fruits and to follow hygiene rules during food preparation.
