Definition of Creeping eruption:

A creeping eruption is infection with dog or cat hookworm larvae.

Causes, incidence, and risk factors:

Hookworm eggs are found in the stool of infected dogs and cats. When the eggs hatch, the resulting larvae infest the soil and vegetation. When you touch this infested soil, the larvae can dig into your skin, causing an intense inflammatory response that leads to a rash and severe itching.

Creeping eruption is more common in countries with warm climates. In the U.S., the southeastern states have the highest rates of infection. The main risk factor for this disease is contact with damp, sandy soil contaminated with infected cat and dog feces. More children than adults become infected.
