Objective To learn and evaluate the effect of health education of schistosomiasis in the Three Gorges Reservoir Area, so as to provide scientific basis for establishing the comprehensive prevention and control model in potential epidemic area of schistosomiasis. Methods Through adopting the multi-stage stratified cluster sampling method, the questionnaires were distributed to residents selected randomly from the demonstration, inside and outside control areas. The survey data were input with EpiData 3.0 software by two reviewers, and the differences among groups were analyzed by using SPSS 18.0 software to further evaluate the effect of health education of schistosomiasis. Results All the questionnaires distributed to 1 420 residents were retrieved (100%). The results of analysis showed that for the residents in the demonstration area, the average score of being aware of schistosomiasis prevention was (7.51±2.89), which was markedly higher than those in the inside (2.52±2.97) and the outside (3.13±3.51) control areas, with significant differences (Plt;0.05); and the passing rates were 78.15%, which was also obviously higher than those in the inside (17.26%) and the outside control areas (32.16%), with significant differences (Plt;0.05). Conclusion The health education of schistosomiasis can improve residents’ knowledge about schistosomiasis prevention, and it is very important to prevent and control the potential prevalence of schistosomiasis in the Three Gorges Area.
Objective To learn the status and compare the effect of improving drinking water and lavatories in potential endemic areas of schistosomiasis in the Three Gorges Reservoir Area. Methods A cluster random sampling method was adopted and a questionnaire survey was conducted to four selected villages and towns before and after organized and large scale drinking water and lavatories improvement in the potential endemic areas of schistosomiasis in the Three Gorges Reservoir Area. Results A total of 807 households in four demonstrate villages and towns were investigated for the baseline survey, while 856 households in the same four villages and towns were investigated for the terminal survey. The popularity rate of using tap water from waterworks went up from 33.58% to 66.12% (P=0.000); the summation of popularity rate of using tap water from both waterworks and water tower made by local residents went up from 76.33% to 96.38% (P=0.000); and the popularity rate of using decontaminated lavatories went up from 53.68% to 78.85% (P=0.000). According to Chi-square test, there were significant differences compared with the popularity rate before improvement (Plt;0.05). Conclusion The condition of intervention villages and towns gets greatly improved through the organized and large scale project of improving water quality and lavatories decontamination, and the potential danger of schistosomiasis is obviously reduced in the Three Gorges Reservoir Area.
