Overview

• Mexico’s federal health ministry has confirmed 33 human miasis cases caused by Cochliomyia hominivorax, with 31 in Chiapas and two in Campeche.
• The first fatality was an 86-year-old woman in Candelaria whose advanced skin cancer was worsened by a screwworm infestation.
• Animal infections have reached 277 across seven municipalities in Campeche, triggering a U.S. ban on Mexican livestock imports at the southern border.
• Officials have intensified epidemiological surveillance, provided wound-care training to vulnerable communities, and erected regional containment barriers.
• A binational sterile-fly release program has been launched to help restore Mexico’s screwworm-free status and safeguard cross-border agricultural trade.
