With many hard efforts, the epidemic prevention and control work in China has borne successful, accelerating the gradual restoration of production, living order and routine medical work. However, there is increasing evidence that many patients with COVID-19 are asymptomatic, but they are potential transmitter of the virus. There are difficulties in screening for asymptomatic infections, which makes it more difficult for national prevention and control of this epidemic. Therefore, it is urgent to develop better screening and laboratory testing for asymptomatic infections with COVID-19 with high speed, sensitivity and specificity. It is also important to improve our risk assessment, prevention and control strategies to further prevent the spread of the epidemic.
经过多方艰苦努力，中国的疫情防控工作取得了成功，加速了生产、生活秩序和日常医疗工作的逐步恢复。然而，越来越多的证据表明，许多新冠肺炎患者是无症状感染者，但他们是病毒的潜在传播者。无症状感染的筛查存在困难，这使得全国防控这一疫情的工作更加艰巨。因此，迫切需要开发出速度快、灵敏度高、特异性强的针对新冠肺炎无症状感染的更好的筛查和实验室检测方法。改进我们的风险评估、预防和控制策略以进一步防止疫情传播也很重要。
