A Maryland resident, who has traveled to Al Salvador, has revealed the New World Screw. First US case reported Tied to travel to a country with a current outbreak.
The Disease Control and Prevention Center confirmed the diagnosis on 4 August. Federal health officials on Monday acknowledged the infection in an email statement.
Health officials in Maryland said that the person had been recovered, and investigators did not find any traffic for any other people or animals.
The CDC investigated the case in coordination with the Health Department of Maryland.

What is New World Screwm?
The New World Screw (NWS) is a fly that lays its eggs in open wounds and body openings. The parasites are usually found in South America and Caribbean.
This is rare in humans, but has been a concern for ranckers, as cattle infections are moving northward through Central America and Mexico. Officials said the CDC is working with the US Agriculture Department.
Insect was a recurring problem for the American cattle industry for decades, known as hot spots with Florida and Texas, until the US wiped it extensively in the 1960s and 1970s.
Given that history, the Maryland case is not the first time an American has ever diagnosed it, Max Scott, a Northern Carolina State University Research said that it has been studied. But this seems to be the first case in a long time in an American resident, he said.
The name refers to a blue-green blowerfly that was somewhat maligned to some extent after an infection in the Devils Penal Colony from the coast of South America in the 19th century. The name of its Latin species broadly translates into “Man Eater”, Scott said.
Female flies lay eggs in an open wound or in an animal or person’s nose, eyes or mouth, which quickly grow in larvae that eat meat.
The screen of the name comes from the magots that can reach for two-thirds inch and it may seem that they are screwing themselves into the meat.
“It’s a bad parasite,” Scott said.
What are the risk and symptoms for people?
US health officials said that the larva does not spread from a person to a person, and they pose very little risk to the public.
The CDC says people suffering from this situation include people living in rural areas, where NWS are spatial, and where livestock is raised, as well as people with open wounds or wounds or wounds and weak population.
Symptoms may also include painful, unexplained wounds or wounds that do not heal. A teletel sign is watching magots around open wounds. Another affected part of another body has a dishonest smell.
How can it be stopped and treated?
To prevent an NWS infection, CDC Urge people to stop the bite of insect, especially when visiting and out of tropical regions. The agency also says that open wounds should be cleaned and covered.
To treat this, doctors sometimes have to remove larvae through surgery.
“If you look or feel magots (larvae) in your body’s wound or other area, contact your healthcare provider immediately,” CDC says. “They will sometimes need to remove the larvae through surgery. Never try to remove or dispose of magots.”
Is more human or animal affairs expected in the US?
This is possible.
For decades, scientists were capable of controlling the bug by releasing the fruitless male flies of the Arabs, but the laps and the migration of people and animals in that work helped them to spread northwards in Central America and Mexico recently.
New genetic techniques are being developed to prevent them, and the US government is increasing its work to control the parasites. But they are a matter of concern.
“I don’t know if it’s going to return to the United States,” Scott said.
If this happens, Texas-Mexico border region is likely to be the first place to see it, he said.
