Breaking News: First Human Infection of New World Screwworm Parasite Confirmed in the US

The first human case of the flesh-eating New World screwworm (NWS) parasite has been reported in the U.S. A person returning from El Salvador was diagnosed with this rare infestation, as confirmed by the Department of Health and Human Services on August 4.

NWS myiasis occurs when the larvae of parasitic flies infest living tissue. While this dangerous pest mainly affects livestock, the health risk to the general public in the U.S. is considered very low at the moment.

The Centers for Disease Control and Prevention (CDC) worked alongside Maryland’s health department to confirm this case. HHS spokesperson Andrew Nixon noted that it’s the first recorded case of travel-associated NWS myiasis in the U.S. and highlights a worrying trend: the pest is typically found in South America and the Caribbean, but it is increasingly making its way north. Currently, it’s confirmed in every Central American nation, including Mexico.

People with open wounds or those who interact closely with livestock in rural areas are at greater risk of infestation. Experts from the CDC explain that as the flies continue to spread, vigilance is necessary for travelers to affected regions.

The U.S. Department of Agriculture (USDA) is working with various agencies, including international organizations, to tackle this outbreak. They warn that when NWS larvae burrow into the flesh, they can cause severe damage to animals and sometimes even humans.

A potential NWS outbreak could pose significant economic threats. The cattle and livestock industry might face losses exceeding $100 billion, according to the USDA. The implications on the economy are serious, and farmers should be informed about preventive measures.

In recent discussions on social media, many users are expressing concern over this new case. Some travelers are sharing tips on how to stay safe, emphasizing that awareness is key while traveling to regions where these pests are common.

As always, staying informed and taking precautions is important. For more details about prevention and response, you can visit the CDC’s website here.
