A Maryland man traveled to El Salvador and became infected with the rare screwworm. Experts warn of health risks.
Screwworm alarm: First case in the USA causes health fears!
An alarming case of screwworm infection has been detected in a traveler in the USA. On August 24, the US Department of Health and Human Services confirmed the first travel-related case of the New World screwworm (Cochliomyia hominivorax), which attacks human skin and tissue. The affected woman, who comes from Maryland, was infected on a trip to El Salvador. It is important to mention that the patient has now fully recovered.
The screwworm is particularly dangerous because the larvae penetrate living tissue and feed on dead tissue. Untreated infestations can be life-threatening. The public health risk in the USA is assessed by health authorities as very low. However, according to a spokesperson for the Department of Health and Human Services (HHS), there is reason for vigilance, especially given that there is an outbreak of the parasite in Central America.
Economic impact and precautionary measures
The spread of screwworm could cause significant economic damage, particularly in Texas, the largest cattle producing state in the United States. Experts estimate that an outbreak of the parasites could cost the industry about $1.8 billion. Ranchers and beef producers are concerned, especially because the U.S. cattle herd is currently at its lowest level in 70 years.
To address the situation, the U.S. Department of Agriculture plans to continue sterile fly release programs. This strategy was successful in eradicating the screwworm in the United States in the 1960s. A new facility to breed these sterile flies is currently being built in Texas and should be ready for use in two to three years.
Advanced health warnings
The Centers for Disease Control and Prevention (CDC) has considered the case a warning signal. Infected wounds can spread very quickly, and the agency emphasizes the need for transparent information sharing. Previously, almost 5,000 cases in animals had already been recorded in Mexico in 2023, increasing the risks for both humans and animals.
Since the screwworm larvae lay eggs in wounds of warm-blooded animals, healthy parts of the body can also be affected. There have been no reported cases in animals in the United States so far this year. Nevertheless, the vigilance of health authorities remains high in order to detect and combat future outbreaks early. The recent incident highlights the potential threat posed by this flesh-eating parasite in the United States.
In summary, the situation surrounding the New World screwworm represents a serious health threat affecting both humans and the livestock industry. Health authorities and experts are working on solutions to prevent the parasite from spreading further. Those interested can find further information on the website Focus and News of Israel read up.
