CDC map highlights Texas and Delaware as top U.S. Naegleria fowleri infections
CDC data show 180 US cases of Naegleria fowleri from 1937–2025, with Texas and Delaware reporting the most exposures; infections are rare but deadly, usually linked to warm freshwater, including recent cases in a Louisiana child and a North Carolina teen. Preventive tips include nose clips or pinching the nose, avoiding digging in shallow water, and keeping the head above water in hot springs.
