Abstract:
Objective To understand the management status of rural sanitary latrine in schistosomiasis epidemic areas of China.Methods Two counties in a province were sampled randomly from total 7 provinces with schistosomiasis prevalence,including Hu'nan,Hubei,Jiangxi,Anhui,Jiangsu,Yunnan and Sichuan,then three villages with schistosomiasis prevalence were selected from each target county as research sites,thirty sanitary latrines in a village were randomly selected for the investigation.Results 58.1% of the 840 sanitary latrines were in better esthetic environment while 37.7% of which were in moderate status and 4.2% were in bed condition.The sanitary latrine without maggot,pupa and fly accounted for 81.5% ;97.0% of the excrement samples at discharge holes were uniform.99.6% of sanitary latrines with trilogy biomass pool exceed more than 30 days for fermentation tank sealed and stored and 62.7%(173/276)of the sanitary latrines cleaned out excrement within half or one year.Among 333 sanitary latrines with three-grid septic,95.2%(317/333)cleaned out excrement within half or one year.The qualified rate of value of night and sedimentation rate of roundworm ovum were 95.5%(745/780)and 61.2%(229/374).90.9%(761/837) of the total 837 households with sanitary latrine used liquid manure as fertilizer,while 4.6% of which discharge liquid manure into neighboring soil and water body;87.9%(736/837)of the households without sanitary latrine used night soil sludge as fertilizer directly,and only 6.9%(58/837)of the households conducted high temperature compost process.Conclusion In the investigated areas,the management of rural sanitary latrine basically meets the requirements of rural sanitation criterion,however,the potential risk for people health still exists in the excrement management.
