Since the 20th century，the biosafety risks with global health and safety as the core have gradually intensified，and major public health crises mainly involving infectious diseases have continued. The population is aging，the harm of chronic non-communicable diseases is increasing，the situation of antibiotic resistance is severe，the impact of global environmental changes continues，and air pollution is serious，which makes the human health risks increase day by day. Human beings，animals and environment are an inseparable whole，and a single discipline or organization can no longer cope with and deal with such complex public health problems. In recent years，One Health has become an internationally recognized key strategy to solve major and complex human health problems. It advocates interdisciplinary，inter-departmental and inter-regional （national） cooperation and exchanges，and effectively integrates the resources of medical，veterinary，environmental and disease control departments to ensure the health of human beings，animals and the environment. At present，there have been many successful cases of the same health practice in the world. The global pandemic in COVID-19 and the successful practice of epidemic control in China have made people realize the importance of the same health strategy，which is also a concrete strategy to achieve the goal of human health community.
