※ 引述《hihimen (aa)》之銘言：
: 今天看了一堆時粉、菸粉一直在推"14天後無感染問題"
: 那問題來了，一直沒本土案例
: 入境台灣也要隔離14天，照時粉的說法，隔離完就安全了呀~
: 台灣為何還要全民戴口罩，是在戴心酸的嗎?
: 這樣好啦，不如全球隔離14天，肺炎病毒自然就消失了
: 泥說好撲好呀??
網路上有找到一篇WHO發佈的隔離措施

如有翻錯或誤解再麻煩指正
Criteria for discharging patients from isolation (i.e., discontinuing
transmission-based precautions) without requiring retesting[1]:
排除隔離病人的條件
For symptomatic patients: 10 days after symptom onset, plus at least 3
additional days without symptoms (including without fever [2] and without
respiratory symptoms)[3]
有症狀的案例: 發病後10天，至少3天無症狀後可以解除隔離
(包含發燒及呼吸道症狀)
For asymptomatic cases[4]: 10 days after positive test for SARS-CoV-2
無症狀的案例: 陽性檢測10天後可解除隔離
裡面的部份結論
Based on evidence showing the rarity of virus that can be cultured in
respiratory samples after 9 days after symptom onset, especially in patients
with mild disease, usually accompanied by rising levels of neutralizing
antibodies and a resolution of symptoms, it appears safe to release patients
from isolation based on clinical criteria that require a minimum time in
isolation of 13 days, rather than strictly on repeated PCR results. It is
important to note that the clinical criteria require that patients’ symptoms
have been resolved for at least three days before release from isolation,
with a minimum time in isolation of 13 days since symptom onset.
基本上大意是病毒在發病後9天就不容易再培養，尤其是症狀較輕的病人
所以基於臨床研究最少隔離13天後是安全的，不需要反覆做PCR檢測
個人認為台灣防疫跟檢疫上也是依據目前病毒研究結果做決策
台灣社區可能有無症狀感染者，雖傳染風險低，但怎麼追蹤的確是個問題
目前這種隔離措施是在平衡感染風險跟醫療資源
再加上現在一直都有開放邊境給國外的商務人事跟本國人入境
所以口罩還是能戴就戴著，也不曉得哪裡會不會有防疫破口
萬一中間有哪個帶病的居家檢疫者在傳染期亂跑就容易擴散
