Notes
1 Positivity was defined as the presence of eggs on one of two slides read by laboratory technicians.
2 Light-intensity infections are defined as 1–4,999 epg of feces for Ascaris lumbricoides infection, 1–999 epg for Trichuris trichiura and 1–1,999 epg for Hookworms. Moderate-intensity infections are defined as 5,000–49,999 epg for Ascaris lumbricoides, 1,000–9,999 epg for Trichuris trichiura and 2,000–3,999 epg for Hookworms. Heavy-intensity infections are defined as >50,000 epg for Ascaris lumbricoides, >10,000 epg for Trichuris trichiura and >4,000 epg for Hookworms.
