### Hookworm Infections: Symptoms, Treatment, and Prevention
**Symptoms**
Hookworms are parasites that can live in your intestines or under your skin. Many people with hookworms don’t show symptoms initially. However, as the infection progresses, you might experience:
- Itchy rash where the hookworms entered your skin
- Abdominal pain
- Diarrhea
- Weight loss
- Fatigue
- Anemia (due to blood loss in the intestines)
**Diagnosis**
To diagnose an intestinal hookworm infection, your doctor will need a stool sample to check for hookworm eggs.
**Treatment**
Treatment depends on the severity of the infection:
- **No treatment:** In some cases, the body may clear the infection on its own, though this can take years.
- **Anthelmintic medications:** These drugs eliminate parasitic worms. Common medications include albendazole, mebendazole, and pyrantel pamoate. For skin infections, topical thiabendazole or oral medications like albendazole or ivermectin can be used.
- **Supplements:** Iron supplements can treat anemia caused by the infection. Nutritional support and other supplements, including folate, may also be necessary.
- **Hospitalization:** In rare cases, severe anemia and congestive heart failure may require hospital treatment.
**Prevention**
To prevent hookworm infections, especially in areas where the soil may be contaminated:
- Avoid walking barefoot on soil that may be contaminated.
- Use proper sanitation and avoid using human feces as fertilizer.
- Drink clean water and eat properly cooked food.
- Some developing countries offer preventive treatment (preventive chemotherapy) to high-risk groups such as pregnant women, children, and people with jobs that expose them to hookworms.
