Frequently Asked Questions

QWhat exactly is cutaneous larva migrans?

Cutaneous larva migrans, often called "creeping eruption," is a skin condition caused by infection with certain types of hookworm larvae. These tiny, worm-like parasites usually live in the intestines of animals like dogs and cats. When humans come into contact with soil or sand contaminated with animal feces, the larvae can penetrate the skin, leading to itchy, red tracks on the body.

QHow do people get infected with this condition?

Folks usually pick up these unwelcome hitchhikers by walking barefoot on contaminated soil or sand. Beaches, parks, and playgrounds where pets might relieve themselves are common hotspots. Direct skin contact with the contaminated ground allows the larvae to burrow in, starting their uncomfortable journey under the skin.

QWhat are the signs that someone might have cutaneous larva migrans?

Look out for raised, snake-like tracks on the skin that itch like crazy. These tracks can appear anywhere on the body but are most commonly found on feet, hands, and buttocks. The rash moves slowly, sometimes a few millimeters to a few centimeters a day, as the larvae make their way through the skin.

QCan cutaneous larva migrans spread from person to person?

Nope, this condition doesn't turn folks into contagious critters. Since it's caused by larvae penetrating the skin directly from contaminated surfaces, there's no risk of it passing from one person to another. So, while it's a good idea to avoid sharing towels or bedding with someone who has an active infection, there's no need to keep them at arm's length.

QHow is cutaneous larva migrans treated?

Good news here! Treatment usually involves oral medications that kill the larvae, bringing much-needed relief from the itching and rash. Doctors often prescribe anti-parasitic drugs, and sometimes topical creams can help soothe the itch. In most cases, with proper treatment, the infection clears up without leaving any lasting damage.

QIs it possible to prevent this condition?

Absolutely, and prevention is pretty straightforward. Wearing shoes and avoiding direct contact with soil and sand in areas where pets are likely to have been is key. Keeping play areas and beaches clean and free of animal waste also goes a long way in preventing the spread of these pesky parasites.

QHow long do the symptoms of cutaneous larva migrans last?

Without treatment, symptoms can linger for weeks or even months as the larvae continue their journey under the skin. However, with prompt medical intervention, the symptoms usually clear up much faster. Once treatment begins, most folks start to see improvement in a matter of days.

QCan animals get cutaneous larva migrans too?

While animals, especially dogs and cats, are the primary hosts for the larvae that cause this condition in humans, they don't get cutaneous larva migrans the way people do. Instead, they can be carriers of the larvae in their intestines. Keeping pets dewormed and away from play areas can help reduce the risk of contamination.
