摘　　要：新型冠状病毒肺炎(COVID-19)疫情已经形成了大流行,目前我国疫情虽然得到了有效控制,但防控仍然面临巨大的压力。作为潜在的传染源,健康携带者及潜伏期携带者在疫情蔓延中起到重要的作用。开展高质量的流行病学调查、特定人群病毒核酸检测,对COVID-19病例发生较为频繁的地点开展小规模的筛查工作,以及加强对不同聚集性疫情调查之间的横向交流等措施,对于聚集性疫情防控具有重要意义。明确COVID-19的感染谱、传染期、是否存在恢复期携带者、院内感染问题及潜伏期的长短,将有助于在今后防控工作中采取有针对性的措施。The coronavirus disease 2019(COVID-19)epidemic has become a pandemic.Although the current epidemic has been effectively contained in China,the prevention and control are still facing great pressure.As a potential source of infection,healthy carriers and latent carriers play important roles in the spread of the epidemic.Some issues are of great significance for the prevention and control of the current epidemic situation,including high-quality epidemiological investigations,detection of viral nucleic acids in specific populations,and small-scale screening in locations where COVID-19 cases occur more frequently,as well as strengthening the horizontal communication among the different clustered epidemic investigations.Clear understanding of the spectrum of infection,infection period,carriers in recovery period,nosocomial infection and the length of incubation period of COVID-19 can help to take targeted measures in the future prevention and control work of this epidemic.
