The U.S. has confirmed the first case of the New World screwworm flesh-eating parasite in a human, according to the Department of Health and Human Services (HHS).

Just two months after reports warily noted that new world screwworms, flesh-eating parasites that are notorious for killing livestock, pets and other animals, hadn’t “made it back into the U.S. yet,” they have—in the form of the country’s first human infection from the current outbreak in Central America.

“This is the first human case of travel-associated New World screwworm myiasis (parasitic infestation of fly larvae) from an outbreak-affected country identified in the United States,” HHS spokesperson Emily G. Hilliard told NBC News in a statement.
