The geographic bug is an infection caused by the larva migrans parasite that usually arises when walking barefoot in places that may contain remains of animal feces, such as sand or fields, for example.
The first symptom that this parasite causes on the skin is the appearance of a small raised red spot on the skin. However, then other symptoms appear as:
- Sensation of something stirring inside the skin;
- Emergence of red lines, similar to paths;
- Intense itching at the site of the lines.
These symptoms can appear up to 30 minutes after the parasite comes in contact with the skin, or it can take a few weeks, since the bug can stay dormant for a few days.
The most affected sites are usually the feet, hands, knees and buttocks, as they are the places that most easily come into contact with contaminated ground.
How is the treatment done?
The treatment to eliminate the geographical bug can be done with the use of medicines or use of an antibiotic ointment, prescribed by the dermatologist, that must be passed on the spot daily. This treatment lasts on average 7 days, and should be done until the end, even if the symptoms disappear days before. Learn more about the remedies used in treatment.
One way to avoid contamination with the footworm is not to walk barefoot on any kind of terrain, whether on asphalt, grass or sand. However, this recommendation is harder to follow on the beach and so it is important to avoid beaches where there are pets such as dogs, for example.
At home, dogs and cats should take antiparasitic medicines every year, so they do not have these larvae in their feces and thus do not contaminate people.
