What is the flesh-eating screwworm parasite detected in a person in the US for the first time?

The first US human case of screwworm was found in Maryland, raising fresh alarm among authorities. The infected person is a traveller who had recently visited Central America, where an outbreak of the parasite has been spreading. It has also raised fears in the US livestock industry, which was declared screwworm-free decades ago

The CDC warns that New World screwworm (NWS) infestations are not only dangerous but also extremely painful. In many cases, maggots can be seen around or inside an open wound. Image courtesy: USDA
