Creeping eruption - Overview
Cutaneous larvae migrans; Ancylostoma braziliense
Definition of Creeping eruption:
Creeping eruption is an 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 larvae infest any contaminated soil and vegetation.
When you come into contact with this infested soil, the larvae can burrow into your skin. They cause 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 that has been contaminated with infected cat or dog feces. More children than adults become infected.
