Abstract:
Objective To understand the prevalence of human intestinal parasite infections in Lahu Ethnic residents so as to provide the evidence for effective control. Methods The prevalence of soil-transmitted nematode infections in local people was determined by Kato-Katz technique and individual sanitary behaviors and habits were requested by a standardized questionnaire in 3 villages of Xiaojie Township,Jinghong City,Yunnan Province. The relationship between intestinal parasite infections and behav-ioral characteristics was analyzed. Results Of 289 subjects,255 individuals were infected with soil-transmitted nematodes;the prevalence was 88.24%. Among the infected individuals,210 were found infected with hookworm and the infection rate was 72.66%;154 subjects were infected with Ascaris lumbricoides and the infection rate was 53.29%;13 were infected with Trichuris trichura,and the infection rate was 4.50%;16 were infected with other parasites and the infection rate was 5.54%. The percentag-es of people with light infection of hookworm,A. lumbricoides and T. trichura were 90.48%,97.40%and 100%,respectively. Con-clusions There is high prevalence of soil-transmitted nematode infections in Lahu Ethnic residents in Jinghong City,but the in-fection intensity was generally low. The control and monitoring of soil-transmitted parasite infections should be strengthened in this area.
