US cyclosporiasis outbreak expands, two dead in Michigan

A cyclosporiasis outbreak in Michigan has resulted in two fatalities, health officials announced. The intestinal infection, caused by the parasites Cryptosporidium parvum or Cyclospora cayetanensis, is primarily contracted through the consumption of food or water contaminated with feces. Symptoms commonly include prolonged diarrhea, severe abdominal pain, nausea, and fatigue, with an incubation period of two to 14 days.

Medical records indicate that both individuals who died had pre-existing severe chronic illnesses, which may have been exacerbated by the cyclosporiasis infection and resulting dehydration. The Michigan Department of Health stated it would not release further details on these cases. Cyclosporiasis is generally not considered fatal in the United States, making these deaths particularly notable.

Nationwide, the U.S. Centers for Disease Control and Prevention (CDC) has recorded a continuous rise in cyclosporiasis cases in recent months. As of July 28, the CDC documented 6,707 laboratory-confirmed cases across the country, with an additional 11,500 suspected cases pending further investigation.

Michigan has been significantly impacted by this outbreak. As of July 30, the state health department reported 193 hospitalizations related to the illness. The total number of cases in Michigan linked to this outbreak has reached 11,234, an increase of 461 cases since July 31. Health officials are actively investigating the source and scope of the outbreak.
