Hookworms are parasitic worms that infect the small intestine, primarily in areas with poor sanitation. They attach to the intestinal wall, feeding on the host's blood, which can lead to anemia and protein deficiency. Symptoms include abdominal pain, diarrhea, and fatigue. Hookworms are transmitted through skin contact with contaminated soil....


What symptoms do hookworm infections cause?

Hookworm infections may lead to abdominal pain, diarrhea, fatigue, and significant anemia due to blood loss where worms attach to the intestine. In children, severe infections can impair growth and cognitive development.

How common are hookworm infections?

Hookworms are a global health issue, particularly in tropical and subtropical regions with inadequate sanitation. They affect hundreds of millions of people, making them among the most common parasitic infections worldwide.

They predominate in warm, moist climates where sanitation is poor, especially where human feces are used as fertilizer or where defecation occurs outdoors, increasing soil contamination.
