Mexico sees 32% jump in flesh-eating screwworm cases since August as cases move north
Mexico recorded 6,703 screwworm cases by mid-September, up 32% since August, with cattle making up most infections and cases spreading toward the U.S. border.
- Senasica's September 26 report found a nearly 32% increase in confirmed New World screwworm cases, with infections becoming more concentrated as they move northward through Mexico.
- Mexico recorded by September 13 that animal infestations exceeded counts through August 17 since the New World screwworm outbreak began last year.
- State-Level data show Chiapas state remains most affected, Veracruz state cases nearly doubled, and Puebla state recorded confirmed cases for the first time about 80 miles from Mexico City.
- The spread has triggered a diplomatic spat as the U.S. blames Mexico for containment gaps, keeping its border mostly closed to Mexican cattle since May while about 42,000 USDA staff were furloughed Wednesday.
- Mexico confirmed on September 21 that a Nuevo Leon case was treated promptly, most infections involved cattle, and the United States reported a travel-associated human case earlier this year.
