然後呢?14天後就放進來?
去年2月就有報導說隔離期14天太短,指揮中心這麼厲害會不知道?

要不要看一下WHO 怎麼說
https://www.who.int/news-room/commentaries/detail/criteria-for-releasing-covid-19-patients-from-isolation
patients whose symptoms have resolved may still test positive for the COVID-19 virus (SARS-CoV-2) by RT-PCR for many weeks. Despite this positive test result, these patients are not likely to be infectious and therefore are unlikely to be able to transmit the virus to another person.
症狀已緩解的患者可能通過RT-PCR檢驗到COVID-19病毒(SARS-CoV-2)陽性達數週。儘管測試結果呈陽性,但這些患者不太可能具有傳染性,因此不太可能將病毒傳播給另一個人。

當前對傳播風險的了解
Current understanding of transmission risk
通過分子檢測(通常是RT-PCR)檢測到病毒RNA的存在,可以確認感染了導致COVID-19的病毒(SARS-CoV-2)。病毒RNA的檢測並不一定意味著一個人具有傳染性並且能夠將病毒傳播給另一個人。決定傳播風險的因素包括病毒是否仍具有復制能力,患者是否有症狀(例如咳嗽,可傳播感染性飛沫)以及與受感染個體相關的行為和環境因素。通常在感染SARS-CoV-2後5-10天,被感染的個體開始逐漸產生中和抗體。這些中和抗體與病毒的結合有望降低病毒傳播的風險。
Infection with the virus causing COVID-19 (SARS-CoV-2) is confirmed by the presence of viral RNA detected by molecular testing, usually RT-PCR. Detection of viral RNA does not necessarily mean that a person is infectious and able to transmit the virus to another person. Factors that determine transmission risk include whether a virus is still replication-competent, whether the patient has symptoms, such as a cough, which can spread infectious droplets, and the behavior and environmental factors associated with the infected individual. Usually 5-10 days after infection with SARS-CoV-2, the infected individual starts to gradually produce neutralizing antibodies. Binding of these neutralizing antibodies to the virus is expected to reduce the risk of virus transmission.

在患者症狀發生前後或疾病發作的前5天中,估計的傳播風險最高
, and the estimated risk of transmission was highest at or around the time of symptom onset and in the first 5 days of illness.

When do people infected with SARS-CoV-2 infect others?
感染SARS-CoV-2的人何時會感染他人?

病毒RNA的檢測並不一定意味著一個人具有傳染性並且能夠將病毒傳播給另一個人。
Detection of viral RNA does not necessarily mean that a person is infectious and able to transmit the virus to another person.
