The New World screwworm, a parasite that was previously eradicated in the United States, has returned and is spreading northward. The pest threatens livestock, wildlife, pets, and potentially humans, according to a report from ScienceDaily.
Researchers at UC San Diego have developed a tracking system designed to predict where the parasite could appear next. The system is intended to support response efforts as officials work to revive an eradication campaign against the flesh-eating pest.
The report notes that containment and prediction are now urgent priorities, but it does not provide details on how far the parasite has spread or how many cases have been reported. The single source points to both renewed danger and a new forecasting tool, without describing any conflicting views.
