At present, the prevention and control of COVID-19 in China has entered a critical period. Recently, various areas outside Hubei Province have gradually begun to resume work and production, but the development of the epidemic situation is still uncertain and complex. A few days ago, researchers gradually began to pay attention to asymptomatic infection of 2019-novel coronavirus and described the disease process of asymptomatic infection and the possibility of being a source of infection. This provided a scientific basis for further optimizing and improving epidemic prevention and control measures. Paying attention to the screening and self-protection of high-risk groups and strengthening the level of detection should be helpful to the detection and management of asymptomatic infection.
目前，中国新冠肺炎疫情防控已进入关键阶段。近期，湖北省以外各地区已逐步开始复工复产，但疫情发展仍存在不确定性且形势复杂。日前，研究人员逐渐开始关注新型冠状病毒无症状感染情况，并描述了无症状感染的病程及成为传染源的可能性。这为进一步优化和完善疫情防控措施提供了科学依据。关注高危人群的筛查和自我防护，提高检测水平，应有助于无症状感染的发现与管理。
