In response to the alarming spread of New World Screwworms, a flesh-eating parasite, multiple counties in Texas have been placed under quarantine. The Texas Animal Health Commission confirmed four cases among livestock in La Salle, Uvalde, Webb, and Zavala Counties, as well as one case in a dog in New Mexico. These parasites, which lay larvae in open wounds, can cause severe infections and even death if untreated. The quarantine restricts the movement of warm-blooded animals from the affected areas to curb the outbreak. The CDC has reported over 2,100 infections in Mexico and Central America this year, raising concerns about public health as the parasites could potentially infect humans. Officials are urging residents to keep wounds clean and covered, and to wear protective clothing to minimize exposure. The New World Screwworms were previously eradicated in the US by 1982, but their return poses a significant threat to livestock and public health in the southern states, particularly as rising temperatures could facilitate their spread. Authorities are closely monitoring the situation as it evolves, with the potential for new information to emerge.
