One source said that the U.S. Centers for Disease Control and Prevention (CDC) had confirmed the infection, notifying livestock stakeholders.<\/p>\n\n\n\n<p>The New World screwworm, a fly whose larvae burrow into living tissue, primarily affects cattle and other warm-blooded animals but can also infect people in rare cases. It causes severe, sometimes fatal damage if untreated. <\/p>\n\n\n\n<p>This is the first confirmed U.S. case since the outbreak began to escalate in Central America and southern Mexico.<\/p>\n\n\n\n<p>Additional human cases are being reported across the region. Guatemala has confirmed 16 cases so far in 2025, Belize reported its first-ever case this week, and Honduras has confirmed 166. Other cases have also been documented in El Salvador, Costa Rica, Panama, and Nicaragua.<\/p>\n\n\n\n<p>On Saturday, Mexican authorities confirmed their 41st case of the year and the first in Yucat\u00e1n, while most cases in Mexico have been concentrated in Chiapas. <\/p>\n\n\n\n<p>The U.S. Department of Agriculture\u2019s Animal and Plant Health Inspection Service (APHIS) said this week that detections of screwworm have surged dramatically, from an average of 25 cases per year in Panama to more than 6,500 cases in 2023. <\/p>\n\n\n\n<p>Since then, the parasite has spread into Costa Rica, Nicaragua, Honduras, Guatemala, Belize, El Salvador, and Mexico\u2014north of the biological barrier in Panama that had contained it for decades.<\/p>\n\n\n\n<p>APHIS announced it is investing nearly $110 million to combat the outbreak in Central America and Mexico to prevent it from spreading into North America. This includes shifting sterile fly dispersal operations to Mexico, the northernmost point of the outbreak, while continuing eradication efforts further south.<\/p>\n\n\n\n<p>\u201cNWS is a devastating pest,\u201d U.S. Secretary of Agriculture Brooke L. Rollins said at an event in Texas on August 15. \u201cIt is not only a threat to our ranching community\u2014but it is a threat to our food supply and our national security.\u201d<\/p>\n\n\n\n<p>The screwworm parasite was eradicated from the United States in 1982, but the escalating outbreak in Central America and Mexico has raised concerns among officials about its possible return.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A person in Maryland has been diagnosed with a rare flesh-eating parasite known as the New World screwworm after traveling from Guatemala, marking the first confirmed human case in the United States, according to Reuters.
