Recent surges in New World screwworm detections, now exceeding 120 confirmed U.S. animal cases across Texas, New Mexico, and Arizona with dozens active, reflect northward spread from Mexico amid insufficient sterile-fly releases and favorable warm, wet conditions supporting fly populations. USDA-APHIS surveillance, including trap monitoring and drone flights, shows rising wild-fly captures since October, while FDA emergency use authorizations for treatments like fluralaner in dogs address gaps in approved options. No formal national emergency declaration has occurred despite the 2025 HHS action enabling these tools, as officials continue phased border port reopenings and sterile-insect dispersal without invoking broader authorities. Upcoming USDA case updates, model runs on eradication thresholds, and the Texas sterile-fly facility's 2027 startup could shift containment trajectories and market-implied odds.
