The National Bureau of Disease Control, the National Health and Health Commission and other 11 departments recently issued the "Action Plan for Accelerating the Elimination of Schistosomiasis (2023-2030)", deploying to speed up the process of eliminating schistosomiasis in my country. It is expected that by 2028, all Counties (cities, districts) where schistosomiasis is endemic have reached the elimination standard.
Coughing, chest pain, bloody sputum, affecting growth and development of children, mental retardation...Schistosomiasis is a major infectious disease that seriously endangers the health of the people and restricts economic and social development.
According to the information released by the Chinese Center for Disease Control and Prevention, schistosomiasis is a parasitic disease caused by cercariae infection of Schistosoma japonicum and adult worms parasitic in the human venous system, and snails are the only intermediate host of Schistosoma japonicum, so the source of infection control is the focus of schistosomiasis prevention work top priority. Only by strengthening source prevention can we reduce the hazards of pathogenic factors and prevent the risk of transmission.
In this regard, the action plan clarifies that we will continue to implement the comprehensive prevention and control strategy of focusing on the control of infection sources and strengthening the control of oncomelania in risky environments. For areas that have not reached the elimination target, areas that have achieved the elimination target, and potential endemic areas, we will implement measures according to local conditions, implement classified policies, and implement precise prevention and control . Decompose the key tasks with the "six major actions", including the control of the source of infection, the comprehensive control of snails, the treatment and management of patients, the monitoring and early warning response actions, the health education promotion actions and the professional ability improvement actions.
Among them, the source of infection control action clearly needs to strengthen the investigation and treatment of the source of infection in the crowd, and increase the rate of feces tests for people with positive blood tests; strengthen the management of the source of infection in livestock, and focus on strengthening the screening of livestock in free-range environments with snails; vigorously promote Prohibit grazing in the environment with snails, promote the adjustment of agricultural industry structure, and develop alternative breeding; strengthen the construction of feces harmless facilities, and combine with rural construction actions to reduce the pollution of feces to the environment.
Anxiang County, Hunan Province used to be a county with severe schistosomiasis epidemics. After the epidemic control in 2008 and the transmission control of schistosomiasis in 2013, it reached the transmission interruption standard in 2019; Jointly investigate the situation of remaining snail spots, promote the provincial snail spot renovation project and snail control, and jointly carry out drug mollusc eradication work; Jiangxi Province includes the oncomelania eradication project in the comprehensive management plan of Poyang Lake area, and actively carries out the construction of schistosomiasis prevention culture and health education... For a long time, my country has taken multiple measures in many places to comprehensively promote the elimination of schistosomiasis.
The "Healthy China 2030" Planning Outline proposes that "by 2030, all endemic counties across the country will reach the standard of eliminating schistosomiasis". "After years of unremitting efforts, as of 2022, 75% of the 452 endemic counties in the country have reached the elimination standard, and the schistosomiasis prevention work has achieved remarkable results." The relevant person in charge of the Department of Health and Immunization of the National Bureau of Disease Control and Prevention introduced that excluding unpredictable natural Due to the impact of disasters and other emergencies, we will continue to increase prevention and control efforts, and it is expected that all endemic counties will be able to meet the elimination standards by 2028.
According to the plan, in order to achieve the overall goal of comprehensively eliminating schistosomiasis by 2030, a "three-step" stage goal is formulated, namely the tackling period (2023 to 2025), the sprint period (2026 to 2028) and the consolidation period period (2029-2030). It is estimated that by 2028, all schistosomiasis-endemic counties (cities, districts) will strive to reach the elimination standard. By 2030, consolidate the elimination results, complete the assessment and acceptance of schistosomiasis elimination, and maintain a stable state of schistosomiasis elimination.
The relevant person in charge of the Department of Health and Immunization of the National Bureau of Disease Control and Prevention stated that in the next step, a working mechanism for effect evaluation will be established and improved, and phased evaluations and final evaluations will be carried out in 2025, 2028, and 2030 respectively to ensure that the goals are achieved as scheduled.
