Cyclospora surge: Michigan leads nationwide cyclosporiasis cases

A spike in cyclosporiasis, a parasite that causes explosive diarrhea, has sickened hundreds and led to at least 20 hospitalizations nationwide, with Michigan reporting more than 170 cases since late June. The CDC and FDA are investigating potential produce-linked sources, but there is no single multi-state outbreak yet. Infections are linked to food eaten in the U.S. (not international travel), and most healthy individuals recover with antibiotics, though symptoms can relapse and risk is higher for the immunocompromised.
