Snopes pulled together 12 archived fact-checks tied to parasitic organisms after a 2026 cyclospora outbreak and renewed online claims about New World screwworm.
The roundup was driven by nationwide attention on cyclosporiasis, with reports of people suffering "explosive diarrhea" during the summer outbreak.
The article also points to a 2025 federal decision led by the CDC that made tracking cyclospora and other pathogens optional, adding context to scrutiny of the outbreak response.
Separate rumors had claimed Department of Government Efficiency cuts caused a U.S. screwworm resurgence, even though the parasite had been largely eradicated domestically since the 1960s.
