From the Long Mail [caution lewd tabloid]:
A terrifying flesh-eating parasite is pouring into the US from across the border in Mexico. The parasite, commonly called a New World Screwworm (NWS), lays hundreds of larvae in the wounds of animals and humans, which hatch within hours and consume their victim’s tissue.
These infestations can lead to deep, painful wounds that become infected and often result in death if left untreated. As the screwworms move closer to Texas, Florida officials reported their first case last week.
