The Centers for Disease Control and Prevention issued a nationwide Health Alert Network Health Advisory on January 20 to share information about the New World screwworm and the recent increase in animal cases in the Mexican state of Tamaulipas, which shares a border with Texas. NWS is a parasitic fly whose larvae feed on the living tissue of warm-blooded animals, including dogs, livestock, wildlife, and, rarely, humans. Female flies lay eggs in open wounds or moist body openings; within about a day the larvae hatch and begin burrowing into healthy tissue, causing painful, rapidly worsening wounds if not treated promptly.
