Preliminary investigation of demographic signatures of intestinal parasitic infection in rural residents of Guangxi Zhuang Autonomous Region in China.

backgroundOur present study was designed to initially unveil the epidemiological characteristics and underlying etiology of intestinal parasitic infection (IPI) in rural residents of Guangxi province in China through conducting a community-based cross-sectional survey. MATERIAL AND

methodsBy use of an epidemiological questionnaire survey and morphologic examination, a total 700 residents from dissimilar regions around rural areas in Guangxi province were recruited for fecal samples to explore ethnic differences in IPI. The fecal specimen was collected and used for microscopic inspection of visible signs of parasitic eggs. In addition, parasitic egg samples were screened and identified to characterize the parasite-bearing IPI cases.

resultsThe statistical epidemiologic data exhibited that the early pathologic signs of ethnicity-sorted IPI-based rural residents occurred in a two-week period, such as headache and itchy skin. Following further one-year tracing, some potential pathological symptoms of rural locales with IPI were screened and identified, including diarrhea and anemia. Insufficient education seemed to be an underlying cause of IPI in rural residents. In addition, further morphologic signs of parasitic eggs and protozoa in IPI-based residents with pathologic symptoms were validated.

conclusionsOverall, these preliminary epidemiologic findings demonstrate that detectable pathologic signs of IPI-based rural residents in Guangxi province were associated with poor education, thus local government needs a strategy for reducing IPI and improving quality of life in locals.
