ABSTRACT
OBJECTIVE: To clarify the role of socio-economy and management in the sustainable schistosomiasis-control in Taoyuan County, an endemic area in hilly region, Hunan Province, China. METHODS: From 1996 to 2011, the data of socio-economy, the management of schistosomiasis control organizations, environment, and the changes in schistosomiasis prevalence were collected in Taoyuan County where schistosomiasis transmission had been controlled since 2008. A sampling survey of schistosomiasis prevalence of human and bovine was performed in 2011 to verify the current status of schistosomiasis transmission. All the data were analyzed statistically to evaluate the role of socio-economy and management in the sustainable schistosomiasis control. RESULTS: During the period from 1998 to 2012, the socio-economy including the residents' productive mode and daily life in Taoyuan County improved dramatically, but the recurrence risk of schistosomiasis endemic still existed due to the retuning of out-going workers and the migrating population. Moreover, the introduction of exotic species of plants and animals may increase the risk. The low running cost of schistosomiasis control organization as well as the efficient and adequate resource allocation in the county was in line with the national requirement to strengthen the rural grass-roots public health system. CONCLUSION: The harmonious development of socio-economy and the scientific and efficient health system in Taoyuan County are the key factors for the sustainable transmission control of schistosomiasis.

OBJECTIVE: To analyze the main endemic indicators and their changing trend of schistosomiasis since the founding of new China for 60 years in Dongting Lake regions. METHODS: A variety of archival data on schistosomiasis epidemiology and control were collected, and several mathematical models were applied to estimate the main endemic indicators of schistosomiasis. RESULTS: Compared to those in 1950s, the infection rates of schistosomiasis among human and cattle in 2010 were declined by 89.3% and 94.7%, respectively; the number of schistosomiasis patients was reduced from 600 thousand to 88 thousand; the number of acute schistosomiasis patients dropped from 2 732 to 18; and that of advanced schistosomiasis patients decreased from 55 thousand to 5 632. CONCLUSIONS: The high priority by government authority, suitable control models according to local conditions and huge resources are the cornerstone of success on schistosomiasis control in Dongting Lake regions.
