Respiratory Protection Recommendations and Guidance against COVID-19 in China Xueyan Zhang, Ning Jia, Ying Qu, Qing Xu, Xinjian He, Zhongxu Wang The Chinese government has taken strong prevention and control measures to fight against the spread of coronavirus disease 2019 (COVID-19), such as promoting public awareness of disease prevention, stopping large gatherings, wearing masks, etc., to reduce the risk of human infection. The source of COVID-19 infection are mainly novel coronavirus infected patients. Asymptomatic infected persons can also become the sources of infection. Respiratory droplets and close contact transmissions have been regarded as the main routes of transmission. There is also a possibility of aerosol transmission in a relatively closed environment for a longer exposure time. Other routes of transmission need to be clarified. The whole population is susceptible (National Health Commission of the PRC, 2020.3.7). Among all control measures, respiratory protection plays a key role in prevention and control of COVID-19. Based on the characteristics of different population groups, the Chinese Center for Disease Control and Prevention (CCDC) has issued recommendations and guidance on respiratory protection against COVID-19.
