RESUMO
Currently, the national schistosomiasis control program of China is moving from transmission interruption to elimination, and there are multiple challenges during the stage moving towards the progression of schistosomiasis elimination, including a high difficulty in shrinking snail-infested areas, unstable achievements for infectious source control, imperfect surveillance system and a reduction in schistosomiasis control and administration. Based on the core suggestions proposed in the 2022 WHO guideline on control and elimination of human schistosomiasis, recommendations on schistosomiasis surveillance system building, development of novel diagnostics, adjustment of the schistosomiasis control strategy and maintaining and improvements of the schistosomiasis control capability are proposed for the national schistosomiasis control program of China in the new era according to the actual status of schistosomiasis control in China. Formulation of the national schistosomiasis control strategy and goal from One Health perspective, verification of transmission interruption and elimination of schistosomiasis, precision implementation of schistosomiasis control interventions with adaptations to local circumstances, development and application of highly sensitive and specific diagnostics are recommended for elimination of schistosomiasis in China. In addition, the implementation of the 2022 WHO guideline on control and elimination of human schistosomiasis may guide the elimination of schistosomiasis in China.

Oncomelania hupensis is the only intermediate host of Schistosoma japonicum, and O. hupensis control is an important measure for schistosomiasis control. With the progress of national schistosomiasis control program, the prevalence of schistosomiasis is low in China; however, there are still multiple challenges for O. hupensis breeding and schistosomiasis transmission risk. Considering the target of the national schistosomiasis elimination program and environmental protection in the new era, the introduction of precision identification, precision interventions and precision assessment into O. hupensis control may facilitate the progress towards elimination of schistosomiasis in China.
RESUMO
This paper reviews the evolution of the schistosomiasis control strategy in China at various stages after the founding of the People’s Republic of China, and analyzes the roles and main problems of the schistosomiasis control strategy at different stages. At the end stage of schistosomiasis elimination, the integrated strategy with emphasis on infectious source control should be continued to be sustained and the problems regarding the implementation of this integrated strategy are analyzed. In addition, the countermeasures to solve these problems are proposed.
RESUMO
In China, the mountainous and hilly schistosomiasis-endemic regions are mainly distributed in 2 provinces of Sichuan and Yunnan. Following the concerted efforts for more than 60 years, great successes have been achieved in schistosomiasis control in mountainous and hilly regions of China. Recently, Sichuan and Yunnan provinces seized the opportunity created in the rural and agriculture development, implemented the integrated strategy with emphasis on infectious source control, utilized modern information techniques, innovated schistosomiasis control models, built sensitive and highly effective surveillance-response systems, and actively tackled the challenges of schistosomiasis elimination, which greatly facilitated the progress towards elimination of schistosomiasis in mountainous and hilly regions of China.

RESUMO
@#The Second Forum on Schistosomiasis Control in China was successfully held in Jiangsu Institute of Parasitic Diseases during the period between 21th and 23th，September，2017. Based on the topic“Implementation of precision control to accelerate the progress towards schistosomiasis elimination”，the forum discussed three macro problems pertaining to how to improve the theory and policy of precision control during the progress towards schistosomiasis elimination in China，and six technical problems regarding how to achieve more precise management of the residual sources of infections and more precise monitoring of transmission risk. Finally，a consensus was achieved that precision control is essential to achieve the goal of schistosomiasis elimination in China.
