[Survey of epidemic status of principal human parasites in Jiangxi Province in 2014].

Objective: To understand and analyze the epidemic status of principal human parasites in Jiangxi Province, so as to provide the evidence for formulating The 13rd Five-Year Project of Parasites Control.

Methods: A survey was performed according to the scheme of The 3rd National Survey of Principal Human Parasites as well as the specific situation of Jiangxi Province. The survey of the soil-transmitted nematodes and intestinal protozoa were performed based on the ecological regions and stratified by economic and geographic situation. The survey of Clonorchis sinensis was performed along with the soil-transmitted nematodes in rural, and was performed by the sample method of random cluster in cities and towns.

Results: Totally 23 606 residents of 92 survey sites from 32 counties were surveyed, all of them were tested for the infection of soil-transmitted nematodes, in which 21,569 residents were tested for intestinal protozoa infection, and 1 486 children were tested for eggs of Enterobius vermicularis. Twenty kinds of intestinal parasites were found, with the total infection rate of 9.64%, and 4.296 millions of patients were reckoned in the whole Jiangxi Province. The infection rate of children of E. vermicularis was 13.73%. The infection rates of C. sinensis and intestinal protozoa were 0.58% and 1.42% respectively. The infection rate of Toxoplasma gondii was 7.50%.

Conclusion: In Jiangxi Province, the infection rates of soil-transmitted nematodes are decreasing but the infection rate of C. sinensis is increasing in local areas, and the control work of parasites still should be strengthened.
