Overview

• Mexico’s Health Ministry reports 41 confirmed human miasis cases tied to Cochliomyia hominivorax and one death of an 86-year-old woman in Campeche.
• Cases are concentrated in Chiapas (36), with additional infections in Campeche (3), Yucatán (1) and Tabasco (1), affecting many patients with comorbidities and wounds on the head, neck and extremities.
• U.S. authorities confirmed a single human case in Maryland linked to travel from El Salvador; the patient recovered with no evidence of transmission, and HHS and CDC assess population risk as very low.
• Regional coordination intensified through an IICA–APHIS/USDA–COPEG workshop involving Central American countries, Mexico and the U.S., alongside planned sterile-male fly production in Texas announced by USDA.
• The parasite primarily targets livestock, with U.S. estimates modeling up to $1.8 billion in potential losses in Texas, and agencies urge wound hygiene, traveler precautions and prompt medical removal of larvae.
