Mapped: Cases of ‘explosive diarrhea’ cyclosporiasis are soaring

Key Points:

• Cases of cyclosporiasis, a parasitic disease causing severe diarrhea, vomiting, and fever, are rising across more than 40 U.S. states, with over 6,000 cases nationwide and Michigan being the hardest hit with 3,300 cases.
• The illness is linked to consuming contaminated fresh produce or water, with lettuce or salad greens suspected as a potential source, though investigations remain ongoing and other food items have not been ruled out.
• The CDC reported 1,645 confirmed domestic cases with 9% hospitalized but no deaths, noting the current outbreak is significantly larger than last year's, and case counts are expected to rise through August.
• Taco Bell is under investigation for a possible connection, having removed some fresh ingredients from menus, but no definitive link has been confirmed by public health officials or the FDA.
• To reduce risk, health experts advise avoiding potentially contaminated foods, thoroughly washing and cooking produce to 158°F, and seeking antibiotic treatment if infected; symptoms can appear between 2 days to 2 weeks after exposure.
