With the frequent occurrence of public health emergencies and the increasing aging of society, the risk of public health emergencies in aging communities is also increasing, which brings great impact to the elderly group. In order to ensure the health and safety of the elderly population and the sustainable development of the aging community, a scientific, efficient, comprehensive and sustainable strategy for the aging community to cope with public health emergencies was provided. According to the three pillars of “health” “participation” and “security” in the framework of active aging, the aging community’s response to public health emergencies was analyzed, and the PDCA(plan-do-check action cycle) optimization framework for coping strategies of public health emergencies in aging communities was constructed from the perspective of active aging, and the corresponding optimization path is proposed accordingly. The PDCA cycle was integrated into the whole process of aging community response to public health emergencies, and it is constantly evaluated and optimized.
