New Guidance Issued on Cyclosporiasis
CDC notes increase in reported cases

The Centers for Disease Control and Prevention (CDC) earlier this week issued updated provider guidance related to Cyclospora cayetanensis infection. Commonly referred to as cyclosporiasis, the infection is an intestinal illness caused by the Cyclospora cayetanensis parasite. The most common symptom is watery diarrhea; other symptoms include anorexia, fatigue, weight loss, nausea, flatulence, abdominal cramping and myalgia. The CDC is currently investigating the increase in reported cases, along with state and local health departments and the Food and Drug Administration. Providers are encouraged to consider a diagnosis of cyclosporiasis in patients with prolonged or remitting-relapsing diarrheal illness. However, as testing for Cyclospora is not routine in most U.S. laboratories, providers should specifically order this testing. Cyclosporiasis is a nationally notifiable disease; health care providers are reminded to report suspect and confirmed cases of infection to public health authorities.
