First U.S. Human Case of Flesh-Eating Screwworm in Years

The first human case of the flesh-eating screwworm parasite has been detected in the U.S., linked to recent travel to El Salvador, raising concerns about potential outbreaks. The parasite, which can devastate livestock and wildlife, is being combated with a sterilization program involving billions of sterile flies, but the threat remains significant, especially for the agriculture industry in Texas and neighboring regions.
