[Practice and development of schistosomiasis control culture in China: A case of Jiangxi Province].

Schistosomiasis control is not only a disease control programme, but also a great social practice activity in China. During the evolution of national schistosomiasis control programmes, the special schistosomiasis control culture has been cultivated and developed, which contains the spiritual connotation of government-led, people-oriented, respect for science and integration of all efforts. The publication of Chairman Mao Zedong's two poems entitled "Farewell to the God of Plague" and the post-script in 1958 was a sign for the formation and development of Chinese schistosomiasis control culture, which always lead the orientation of development and practice of schistosomiasis control culture building. The schistosomiasis control culture provides powerful spiritual motivation and supports to schistosomiasis control programmes in China, and improving the building of schistosomiasis control culture is of great significance to strengthen our belief in achieving the goal of schistosomiasis elimination, mobilize all social resources, accelerate the progress towards elimination of schistosomiasis and facilitate the high-quality development of healthcare services. Chinese schistosomiasis control spirit is the refinement from the cultural connotation of the long-term schistosomiasis control programmes in China, and is the most essential and concentrated embodiment of the schistosomiasis control culture. This article describes the great significance of two poems entitled "Farewell to the God of Plague", summarizes the connotation and role of schistosomiasis control spirit, and introduces the practice, development and innovation of schistosomiasis control culture building in Jiangxi Province.

[Challenges and countermeasures of schistosomiasis elimination in Jiangxi Province].

Jiangxi Province was once one of schistosomiasis heavy endemic provinces in China. Thanks for more than 60 years' unremitting effort, great achievements have been obtained in schistosomiasis control in this province. This paper reviews the control history of schistosomiasis, and demonstrates the current epidemic situation of the disease in Jiangxi Province, and its contribution to national schistosomiasis control achievements. The difficulties and challenges of schistosomiasis elimination in this province are analyzed and the countermeasures are also put forward accordingly.

[Study on distribution status of Oncomelania hupensis, the intermediate host of Schistosoma japonicum in Jiangxi Province â ¡ Spatial-temporal distribution of snail-infested environments].

OBJECTIVE: To grasp the status of Oncomelania hupensis snail-infested environments in schistosomiasis endemic areas of Jiangxi Province, and establish the spatial database of snail-infested environments with the administrative village as the unit. METHODS: The spatial and temporal distributions of the historical snail environments, existing snail environments, and suspicious snail-infested environments were analyzed by the historical data review and field investigations. RESULTS: The distribution of snail-infested environments in Jiangxi Province included two popular types of lakeshore and hills. The O. hupensis snail-infested environments were mainly concentrated in the Poyang Lake area, which accounting for 66.97% of the total snail-infested areas. The potential snail-infested environment area was 204 745.48 hm2, among which the potential snail-infested environment areas in the lakeshore and hills were 146 548.58 hm2 and 58 196.90 hm2, accounting for 71.58% and 28.42%, respectively. The real existing snail area was 83 234.50 hm2, among which the real existing snail areas in the lakeshore and hills were 80 890.81 hm2 and 2 343.69 hm2, accounting for 97.18% and 2.82%, respectively. The compressed snail area was 114 253.30 hm2 with a compression rate of 57.85%, of which the compression rates in the lakeshore and hills were 46.51% and 94.97%, respectively. In the four types of snail-infested environments, the areas of Type I, Type II, Type III and Type IV accounted for 55.77%, 25.75%, 13.91% and 4.57% of the total area, respectively. CONCLUSIONS: The spatial database of O. hupensis snail-infested environments is established comprehensively and systematically, that will be conducive to tracking and performing the dynamic updates of the data of snails, so as to provide an important technical support for investigation and monitoring in the future.
