The New World Screwworm (NWS), an invasive flesh-eating fly, is moving towards the US, following the migrant caravan routes. It lays larvae in tissue wounds, leading to severe infections and potential death if untreated. Cases have already been reported in southern Mexico. With expected climate changes, NWS may spread to southern US states by 2055, threatening both human health and cattle. Historical context indicates significant financial losses previously suffered by the US due to NWS. The potential for rising beef prices and food shortages looms, highlighting the need for urgent measures against this emerging threat.
The New World Screwworm (NWS) lays hundreds of larvae in the wounds of animals and people, which hatch within hours and consume the victim's tissue.
Researchers fear there may be no way of stopping the flies at the US-Mexico border and they'll start infesting the South within two decades due to rising temperatures.
NWS infestations can lead to deep, painful wounds that become infected and often result in death if left untreated.
Although the threat of widespread outbreaks of NWS among people in the South, US shoppers would quickly feel the impact of this species killing local cattle.
