What kind of doctor treats Creeping Eruption?
A primary care doctor, a dermatologist (a skin doctor), or an infectious disease doctor can diagnose and treat creeping eruption. Doctors who focus on travel health often see it too. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is creeping eruption?
Creeping eruption is also called cutaneous larva migrans, or CLM. It is an infectious syndrome caused by hookworms. The skin is infested with hookworms from animals.
It usually spreads when animal feces put eggs in the soil. The larvae, or baby worms, enter the skin through direct contact.
Symptoms
It causes an extremely itchy, linear or winding skin lesion. The larvae move slowly in the top layers of the skin. They move in a snake-like way. The rash is itchy and raised.
The most common first sign is a small reddish bump. It grows into a winding, itchy rash. The rash moves slowly, from less than 1 cm to 2 cm per day.
It can affect any exposed area. The most common place is the feet.
Causes and who gets it
Adult hookworms live in the intestines of dogs and cats. Eggs are shed in feces and hatch in the soil.
Hookworms are found mostly in warm climates. These include the southeastern United States, Latin America, the Caribbean, Southeast Asia, and Africa. It is often most common in wet seasons.
People often have a history of travel to these areas and of walking barefoot.
How doctors diagnose it
Doctors usually diagnose it by looking at the rash and asking about recent travel. Blood tests are not needed.
The slow speed of the rash helps tell it apart from other migrating infections. A deeper, fast-moving rash may be a different problem, called larva currens, caused by another worm.
Treatment
It often clears up without treatment. It is usually self-limiting after 4 to 6 weeks. But the larvae can keep moving for months, and the itch may be severe. It can interfere with sleep.
Albendazole and ivermectin are both effective medicines. Steroid creams can be used to relieve severe itching. Cure rates with treatment are near 100 percent.
Freezing the lesion has been shown to be largely ineffective and should be avoided. Antibiotics are ineffective against the infection.
Mebendazole, another worm medicine, should not be used as a first choice.
Wearing protective footwear can help prevent it. Towels do not always protect.
When to see a doctor
A winding, very itchy rash after travel or walking barefoot is a reason to see a doctor, who can usually diagnose it from the rash and your travel history. A skin infection can complicate the rash.
In rare cases, more serious disease can result from invasion of deeper organs. Call 911 or go to the emergency room if you have trouble breathing, confusion, or fainting.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can look at the rash and ask about your travel. They can also treat it or refer you to a skin or infectious disease doctor.
Common questions
Does creeping eruption go away on its own?
Often, yes. Resolution without treatment is the rule rather than the exception. The larvae may keep moving for months.
How do you catch creeping eruption?
You catch it when larvae in soil that animal feces have contaminated enter your skin.
How is creeping eruption spread?
It is most commonly spread by soil that animal feces have contaminated.
Can wearing shoes help prevent creeping eruption?
Yes, wearing protective footwear can be effective. Banning dogs from beaches may also decrease the larvae in the soil.
