Mexico reports surge in human myiasis cases and first fatality
Mexico's health surveillance system recorded 361 human myiasis cases through week 25 of 2026, with three deaths and 17 new cases in the latest week. The total number of confirmed infections for 2025‑2026 reached 478. Cases are concentrated among elderly men in poor rural municipalities of the Sierra Norte, Sierra Negra and the Tehuacán valley, where access to medical care is limited. The first recorded patient, an 81‑year‑old man from Vicente Guerrero, was diagnosed in March after larvae infested his oral cavity. Separate reports cite 37 infections in Yucatán and three cutaneous cases in Morelos. Health authorities attribute the outbreak to the parasitic fly Cochliomyia hominivorax, which deposits eggs in open wounds. Officials stress that removal must be performed medically and urge immediate wound cleaning and hygiene to prevent further spread.
