WHAT IS CUTANEOUS LARVA MIGRANS?
Cutaneous larva migrans is a parasitic skin infection caused by hookworm larvae that usually infest cats, dogs and other animals. Infection can happen when your skin comes into contact with the larvae, typically in contaminated soil or sand.
The signs of Cutaneous larva migrans typically appear 1 to 5 days after infection, although sometimes it takes longer. Common signs and symptoms include:
- Red, twisting lesions that grow.This is due to the movement of the larvae under your skin. Lesions can move up to 2 centimeters in a day.
- Itchiness and discomfort. Lesions may itch, sting, or be painful.
- Swelling can also be present.
- It can occur anywhere on the body, although it most often occurs on areas likely to be exposed to contaminated soil or sand, such as the feet, buttocks, thighs, and hands.
Because lesions can be intensely itchy, they’re often scratched. This can break the skin, increasing the risk for a secondary bacterial infection.
Cutaneous larva migrans is a self-limiting condition. The larvae under the skin typically die off after 5 to 6 weeks without treatment. However, in some cases it may take longer for the infection to go away. Use of topical or oral medications may help to clear the infection faster.
