Infectious Disease Compendium

Necator americanus

Microbiology

Hookworm. A round worm.

Epidemiologic Risks

Walking in human feces. Really. Eggs pass in the stool and you walk in the stool and they invade through your skin. Beats eating them. Barely.

Syndromes

Ground itch: an intense pruritus, erythema, and a vesicular, papular rash where the larva penetrated.

Iron deficiency anemia is the most common manifestation of bowel infestation, but malnutrition in all its forms.

Treatment

Mebendazole 100 mg bid x 3 days.

Notes

H.L. Menken, America's second greatest writer, in his wisdom, referred to the US South as the hookworm belt. I look forward to your abusive e-mail in reply.
