As a new infectious disease, the epidemic process of COVID-19 has a series of special influencing factors and conditions. In this paper, some obvious characteristics of this widespread epidemic are discussed, including the new pathogen making people feel confused, the slow onset bringing confusion to the clinic, the miscellaneous source of infection also causing confusion to prevention and control work, the easy route of transmissions leading to a sharp increase of confirmed cases, the high susceptibility of the population leading to a high incidence, and the natural epidemic process coupled with the complexity of natural factors and the superposition of social factors. The positive and effective prevention and control strategies and measures adopted by China have greatly changed the natural epidemic process and trajectory of this epidemic, which has been highly affirmed by the expert group of the World Health Organization and praised by many countries and international organizations. However, to sum up carefully and think deeply, it will be a long-term and arduous work to plan and realize public health security in China and even the world in the future.
作为一种新型传染病，新型冠状病毒肺炎（COVID-19）的流行过程具有一系列特殊的影响因素和条件。本文探讨了这一广泛流行的一些明显特征，包括新型病原体让人感到困惑，发病缓慢给临床带来困扰，传染源繁杂也给防控工作造成困惑，传播途径易导致确诊病例急剧增加，人群易感性高导致发病率高，以及自然流行过程加上自然因素的复杂性和社会因素的叠加。中国采取的积极有效的防控策略和措施极大地改变了这一疫情的自然流行过程和轨迹，得到了世界卫生组织专家组的高度肯定，并受到许多国家和国际组织的赞扬。然而，仔细总结和深入思考，未来在中国乃至世界规划和实现公共卫生安全将是一项长期而艰巨的工作。
