A flesh-eating screwworm larva was found in a person who had traveled to El Salvador. While the case is concerning, health officials emphasize the low risk to the general public. Screwworms, largely eradicated in the U.S. since the 1960s, are more common in livestock. A recent outbreak in Central America and Mexico prompted preventative measures, including targeted surveillance and sterile insect releases. The risk is primarily for those with open wounds traveling to affected areas. Authorities are working to contain the outbreak and prevent its spread into the U.S.
