Starting yesterday, the information of the asymptomatic infected persons will be included in the daily COVID-19 updates. How to define asymptomatic infected persons of COVID-19? Can asymptomatic infected persons spread the disease? What measures will be taken to strengthen the prevention and control of asymptomatic infections? The answers can be found in FAQs on the Prevention and Control of the Spread of COVID-19 Caused by Asymptomatic Infected Persons released by the National Health Commission.  

4月1日起,每日疫情公報公布無癥狀感染者情況。什么是新型冠狀病毒無癥狀感染者?無癥狀感染者有傳染性嗎?如何做好無癥狀感染者防控管理?就此,國家衛健委發布了《關于新型冠狀病毒無癥狀感染者的防控工作答問》。

Q: How to define asymptomatic infected persons of COVID-19?

什么是新型冠狀病毒無癥狀感染者?

Asymptomatic infected persons of COVID-19 (hereinafter referred to as asymptomatic infected persons) refer to those who do not show any relevant clinical symptoms, such as fever, cough, sore throat and other self-perceived or clinically recognizable symptoms, but whose respiratory tract specimens test positive for COVID-19. Asymptomatic infected persons can be divided into two categories:

新冠病毒無癥狀感染者(以下簡稱無癥狀感染者)是指無相關臨床癥狀,如發熱、咳嗽、咽痛等可自我感知或可臨床識別的癥狀與體征,但呼吸道等標本新冠病毒病原學檢測陽性者。無癥狀感染者可分為兩種情形:

One is that infected persons who test positive in the nucleic acid test do not show any self-perceived or clinically recognizable symptoms after the 14-day observation of the incubation period and the infection has been asymptomatic. 

一是感染者核酸檢測陽性,經過14天潛伏期的觀察,均無任何可自我感知或可臨床識別的癥狀與體征,始終為無癥狀感染狀態;

The other is that infected persons who test positive in the nucleic acid test do not show any self-perceived or clinically recognizable symptoms when sampling, but later develop some clinical symptoms. That is "asymptomatic infection" during the incubation period.

二是感染者核酸檢測陽性,采樣時無任何可自我感知或可臨床識別的癥狀與體征,但隨后出現某種臨床表現,即處于潛伏期的“無癥狀感染”狀態。

Q: Can asymptomatic infected persons spread the disease?

無癥狀感染者有無傳染性??

According to the monitoring data released by the State and some provinces, some asymptomatic infected persons have caused second-generation transmission among their close contacts, and they have set off a small number of clusters of infections according to epidemiological investigations. Studies with small sample sizes have shown that the viral loads in the respiratory samples of asymptomatic cases do not demonstrate distinct difference from those of confirmed cases.

根據國家和部分省份開展的密切接觸者監測數據,無癥狀感染者的密切接觸者存在二代病例續發,流行病學調查中發現個別由無癥狀感染者導致的聚集性疫情,有小樣本量的研究顯示無癥狀感染者呼吸道樣本中的病毒載量與確診病例沒有太大差異。

According to the current monitoring data and research, asymptomatic infected persons are contagious, but the length of the contagion period, the strength and pathway of transmission need to be further studied.

綜合目前的監測和研究,無癥狀感染者存在傳染性,但其傳染期長短、傳染性強弱、傳播方式等尚需開展進一步科學研究。

Some experts believe that the risk of spreading the virus caused by asymptomatic infected persons is relatively lower than that by confirmed patients because asymptomatic infected persons show no clinical symptoms such as cough and sneezing though the pathogenic nucleic acid can be found in their respiratory tract specimens. 

部分專家認為鑒于無癥狀感染者的呼吸道標本能檢出病原核酸,但由于無咳嗽、打噴嚏等臨床癥狀,病原排出體外引起傳播的機會較確診病例相對少一些。
