US-Mexico screwworm outbreak: containment and human impact

Overview

The New World screwworm outbreak continues to impact the U.S.–Mexico border, with containment efforts facing new biosecurity challenges. While the USDA-APHIS has lifted the infested zone in New Mexico following a single confirmed case in a dog on 7 June 2026, the parasite remains a threat near the border. A recent case was detected in a sheep in Coahuila, Mexico, approximately 31 miles from the United States. The resurgence, which began in 2023, has resulted in over 144,000 animal cases and 1,100 human cases across the region.

In northern Mexico, authorities are implementing biological control measures. In Coahuila, officials are releasing approximately 2.5 million sterile flies weekly via aerial dispersal to manage active cases. This strategy aims to secure authorization for the state to export live cattle to the United States. In Chihuahua, the pest has affected 29 municipalities, with 64 active cases reported as of early September, primarily affecting bovines, canines, and equines. While Chihuahua currently uses land-based dispersal, officials are awaiting increased sterile fly production from Chiapas to begin aerial operations.

In Tamaulipas, the government has intensified surveillance to contain 18 positive cases, which include livestock and small species such as dogs. Specialized brigades are being deployed to high-risk areas in the southern and central regions, including Aldama, Soto la Marina, and Ciudad Victoria, to prevent further spread.

Human impact remains severe. Mexico has recorded four deaths from the parasite in 2026, with the latest fatality in Veracruz during the week of 16–22 August. Since the start of 2026, Mexico has confirmed 516 human cases, totaling 633 since 2025. Veracruz remains the most affected state, accounting for approximately 21% of this year’s national total.
