What Is Hookworm-Related Creeping Eruption?
Creeping eruption, also called cutaneous larva migrans, is a skin infection caused by hookworm larvae. These tiny parasites can enter the skin after contact with contaminated sand or soil, most often in warm climates.
The condition creates a red, winding rash that slowly moves under the skin. While the infection can be very itchy and uncomfortable, it is usually temporary and treatable.
People often become infected after walking barefoot or sitting on contaminated beaches or soil. The condition is more common in tropical and subtropical regions where infected dogs and cats may spread hookworm eggs into the environment.
Symptoms
Hookworm-related creeping eruption usually develops after direct contact with contaminated ground or sand. Symptoms may appear within a few days, but in some cases they can take several weeks to show up.
Common symptoms include:
- Intense itching
- A red, raised rash with twisting or snakelike lines
- Blisters or small bumps
- Mild swelling or skin irritation
- Rash on the feet, legs, buttocks, hands, or other exposed areas
How Is It Diagnosed?
Healthcare providers usually diagnose creeping eruption by examining the rash and asking about recent travel or outdoor exposure. The appearance of the winding skin tracks is often enough to identify the condition.
In most cases, additional testing is not needed.
How Is It Treated?
Treatment focuses on stopping the parasites and easing itching and irritation. Providers may recommend antiparasitic medicines such as albendazole or ivermectin. Some mild cases can also be treated with topical medication applied directly to the skin.
Anti-itch creams or oral medicines may help reduce discomfort while the skin heals. Although the infection can go away on its own over time, treatment often helps symptoms improve faster and prevents complications from scratching.
Most people recover fully within a few weeks.
