Investigation on status of major human parasitic diseases in Donghai County

Objective To understand the current endemic status of major human parasitic diseases in Donghai County in order to provide the basis for making practical control measures.Methods The infection rates and densities of major human intestinal parasites were investigated according to the methods of National Investigation Scheme on Major Human Parasitic Diseases,and the data of society,economy and disease control were collected and analyzed.Results The two investigated spots included 983 people and 30 persons with the infections of 4 intestinal parasites were found,and the total infection rate was 3.05%,and the infection rates of the two spots were 3.00% and 3.12%,respectively.Four kinds of major intestinal parasites were hookworm,Ascaris lumbricoides,Trichuris trichiura and Enterobius vermicularis,and the infection rates of hookworm,Ascaris lumbricoides and Trichuris trichiura were 0.51%,0.81% and 1.83%,respectively,and the infection densities were all slight.The people with multiple parasites were 3.33%.The infection rate of Enterobius vermicularis was 11.73% in children under 12 years old.Conclusions The prevailing parasites in major human parasites are intestinal nematodes in Donghai County.The endemic intensity decreases obviously compared with the condition of 10 years ago.The difference of the two endemic spots is not significant.The endemic is related to the disease control program and sanitation habits of the residents.The enterobiasis control in the children under 12 years should be emphasized.
