The Department of Health and Human Services (HHS) and Centers for Disease Control and Prevention (CDC) identified a case of the flesh-eating parasite on August 4 in a person in Maryland who returned to the U.S. after traveling to El Salvador, the U.S. Department of Agriculture (USDA) said in an August 26 announcement.
Note: Although previously contained below the Darian Gap using SIT, the screwworm has escaped this barrier and has been reported first in Key Deer in Florida and then in multiple livestock from numerous locations in Mexico. This has forced the USDA to re-establish fly production facilities in Texas to renew mass releases to re-establish eradication near the US-Mexico border. This series of events serves to remind us that even eradication can be temporary and must be partnered with continued surveillance to document success.
