Knowledge of, attitudes towards, and practice relating to schistosomiasis in two subtypes of a mountainous region of the People’s Republic of China

Background:Schistosomiasis japonica is still endemic in the People’s Republic of China(P.R.China)in five provinces of lake and marshland regions and in two provinces of mountainous regions.Studies elucidated that individual and community perception,attitudes towards schistosomiasis,and hygiene behaviors were crucial factors for preventing schistosomiasis.This study sought to assess the knowledge of,attitudes towards,and practices(KAP)relating to schistosomiasis in two subtypes of a mountainous region in Eryuan County,Yunnan Province,P.R.China.The study’s aim is to make suggestions for establishing more specific and effective control measures for disease transmission and interruption in two subtypes of a mountainous region with low-level infection rates.Methods:A cross-sectional study of 3,000 inhabitants was carried out in the Yongle(plateau basin)and Xinzhuang(plateau canyon)communities of Eryuan County,Yunnan Province in November and December 2011.Stratified cluster random sampling was undertaken using a uniform set of quantitative questionnaires administered by trained assistants.This was further supported with qualitative data from in-depth interviews(IDIs)conducted with ten farmers and ten students.All participants were examined for schistosomiasis using both a serological test(indirect hemagglutination assay[IHA])and a stool examination(Kato-Katz).Results:The total schistosomiasis knowledge rate in Yongle(83.4%)was significantly lower than that in Xinzhuang(95.5%).In both communities,among the respondents aged 15 years or below,more than one third didn’t know the name,endemic areas,and animal reservoirs of schistosomiasis.The majority of respondents in Eryuan acquired their schistosomiasis knowledge from doctors,followed by handouts and hearing from others.The infection rate was once the highest in Yongle,but is now the highest in Xinzhuang,where there are more risk factors for schistosomiasis,such as frequently grazing cattle,digging vegetables or cutting grass in the field,as well as raising cattle by free grazing.Conclusion:In short,Eryuan County’s overall knowledge rate of schistosomiasis was found to be high.Due to various dominating risk factors,different control strategies should be designed keeping in mind the two different subtypes of endemic areas for schistosomiasis in mountainous regions,namely plateau basins and plateau canyons.
