What is screwworm?
Dig deeper:
The New World screwworm (NWS) is a species of parasitic flies that can cause myiasis, which is a parasitic infestation that feeds on live tissue.
It primarily affects livestock, but people can also become infested.
Officials say you are at a higher risk of NWS if you travel to South America and the Caribbean, where it is typically found.
Symptoms and prevention
What you can do:
The CDC says that NWS infestations are very painful and could result in maggots around or in an open wound, nose, eyes or mouth.
Symptoms can also include:
- Unexplained skin lesions (wounds or sores) that do not heal.
- Skin wounds or sores that worsen over time.
- Painful skin wounds or sores.
- Bleeding from open sores.
- Feeling larvae movement within a skin wound or sore, nose, mouth, or eyes.
- Seeing maggots around or in open sores.
- A foul-smelling odor from the site of the infestation.
"Prevention is key to protecting yourself from myiasis," according to the CDC, which offers these tips:
- Prevent insect bites, especially when visiting tropical areas and spending time outdoors
- Keep open wounds clean and covered.
- Wear loose-fitting, long-sleeved shirts and pants, and socks to limit areas where you could get bitten.
- Use an EPA-registered insect repellent.
- Treat clothing and gear with products containing 0.5% permethrin.
- Sleep indoors or in rooms with screens.
