The CDC has activated a Level 3 emergency response following the detection of New World screwworm infestations in animals across parts of southern Texas and New Mexico. This alert supports collaborative efforts with the USDA and state health services to contain the parasite. While primarily affecting livestock and wildlife, human infections are possible, though the public health risk is currently considered low.
