Abstract:
Objective To understand the epidemic status of principal human parasitosis in the ecological region of Huaiyang hills of Henan Province. Methods According to the scheme of The 3rd National Survey of Principal Human Parasites made by National Institute of Parasitic Diseases,the survey was performed based on the ecological regions. The stratified cluster sampling was made combined with the economic and geographical conditions. The infections of intestinal helminths and protozoans in per-manent residents were respectively detected by Kato-Kats technique and iodine solution. Trichuris trichiura infection was detect-ed by the cellophane swab method in children aged 3 to 6 years. Results Totally 6710 residents in 26 survey spots from 9 coun-ties were detected,in which 528 children aged 3 to 6 years were detected for T. trichiura infection. Eleven kinds of parasites were found in this survey,including 5 species of helminthes and 6 species of protozoans. The infection rates of overall parasites, helminthes and protozoans were respectively 1.65%,1.07%and 0.61%. The infection rate of T. trichiura in the children aged 3 to 6 years was 3.79%. Only 0.10 percent of the infections were co-infection,and all were infected by 2 kinds of parasites. The principal parasites in this district were Ascaris lumbricoides(0.31%),Blastocystis hominis(0.28%)and hookworm(0.27%). The T. trichiura infection rate among children was 3.79% by the cellophane swab method. The infections of protozoans were found in all age groups. In the group aged 9 years and below,the maximum kinds of parasites were found. Conclusion The in-fection rates of principal human parasites in Huaiyang hilly ecological region of Henan have decreased sharply ,but more efforts still should be paid on the prevention and control of parasitosis in children.
