Prevalence and intensity of Ancylostoma duodenale and Necator americanus infestations in school children from the Lolodorf health district (Cameroon) Human hookworms in southern Cameroon.

Abstract

Parasitological investigations on Ancylostoma duodenale and Necator americanus infesta tions were carried out in 541 school children from Lolodorf health district, South Region of Cameroon. Their stools were analyzed using the Kato-Katz technique and the faecal culture of hookworm eggs. Among the 541 children investigated, 4 were infested with A. duodenale (0.7%), 13 with N. americanus (2.4%) and 11 were co-infested with both nematodes species (2.3%), giving a global prevalence of 5.17%. No significant difference between these prevalences in relation to the child sex or age was noted. The low prevalence found for these hookworms could attributed to mass deworming campaigns against soil transmitted helminths implemented in Cameroon.
