中国流感疫苗预防接种技术指南(2021 — 2022)

流行性感冒（简称流感）与新型冠状病毒肺炎（简称新冠肺炎）均为呼吸道传染病，若二者合并感染，不但会加重病情、延长病程，且会使死亡率升高，特别是对老年人、儿童及慢性病人群风险更大，同时还会给患者个人、家庭及社会带来沉重的疾病经济负担。因此，在全球新冠肺炎大流行背景下，加强对流感的防控具有重要的现实意义。本文从中国流感防控现状和长期目标及新冠肺炎疫情防控背景下流感防控的新形势和新要求2个方面概述目前中国流感疾病负担、问题与挑战，并提出相关流感防控的应对策略。

Epidemiologic and economic burden of influenza in the outpatient setting: a prospective study in a subtropical area of China

Influenza and coronavirus disease 2019 (COVID-19) are both contagious respiratory illnesses. A co-infection of influenza and COVID-19 will prolong the illness, worsen the severity of COVID-19 symptoms and increase fatality, especially for senior citizens, children and people with chronic diseases; the co-infection condition could also bring heavy disease and economic burden to the sufferers, their families, and the society. Therefore, it is crucial to enhance influenza prevention strategies under the global COVID-19 pandemic. In this paper, we summarize the disease and economic burden of influenza and discuss current problems and challenges in influenza prevention and related researches in China.
