U.S. reports first case of flesh-eating screwworm in decades, in Maryland traveler from Central America.

The U.S. has reported its first human case of the New World screwworm, a flesh-eating parasite, in a Maryland patient who recently traveled from Central America. The Centers for Disease Control and Prevention confirmed the diagnosis, raising concerns for the livestock industry. The parasite, typically found in cattle and other warm-blooded animals, can cause severe damage if not treated promptly. The U.S. government emphasizes the low risk to public health but is planning a sterile fly facility in Texas to prevent potential outbreaks.
