感染性疾病流行现状、防控挑战与应对

近几十年来，尽管全球感染性疾病负担大幅度下降，但传统感染性疾病相关的发病和死亡仍不容忽视。另外，受全球气候变化、快速城市化和人口快速流动等多种因素影响，新发感染性疾病成为全球重要的公共卫生威胁。无论是全球还是我国，均面临传统和新发感染性疾病的双重威胁。新形势下的感染性疾病防控需加强全球合作，强调全社会跨学科、跨部门共同参与。

Epidemiological status,challenge of prevention and control,and response strategy of infectious diseases

During recent several decades,the global disease burden of infectious diseases decreased substantially.However,morbidity and mortality associated with common infectious diseases should not be overlooked.In addition,under the influence of such factors as global climate change,rapid urbanization,and rapid population movement,new emerging infectious diseases become severe threat to global public health.Both the whole world and China are threatened by both common and new emerging infectious diseases.The control and prevention of infectious diseases under new circumstances should strengthen global cooperation,and require interdisciplinary and trans-department collaboration.
