The Relationship Between Nail Hygiene and the Incidence of Intestinal Parasite Infections (Intestinal Parasites) in Scavengers at Final Disposal Sites (TPA) Terjun Village, Medan Marelan District, Medan

Background. Intestinal parasitic infections are a global problem in humans, especially in developing countries. Indonesia has an intestinal parasitic infection prevalence rate of 45-65%. Intestinal parasitic infections are caused by helminths, namely Ascaris lumbricoides, Hookworms, Trichuris trichiura, and protozoa. The mode of transmission is ingestion of eggs or other infective forms. Nails are the body part that transmits infective forms of intestinal parasites orally. Scavengers work to sort garbage and have contact with the ground with a high risk of intestinal parasite infection. Objective.
