新冠疫情的流行期可以追溯至2019年底和2020年初。最初在武汉发现，世界卫生组织确认了这种病毒，并很快在全球蔓延。据报道，COVID-19于2020年1月开始在美国引起大流行 3。随后，世界卫生组织于2020年3月11日宣布COVID-19为全球流行病 9。重要决策时间轴显示，2020年1月至3月，世界卫生组织不断发布有关COVID-19的提示和建议，表明病毒在这一时期已经引起广泛关注 5。因此，可以认为，新冠疫情的流行期始于2019年底持续至2020年初，并在之后演变为全球大流行。
除了起始时间，对COVID-19的来源也引起了广泛关注。病毒最初被认为是由动物传播给人类，而非实验室泄漏 4。然而，有越来越多的证据表明COVID-19可能起源于中国武汉的实验室 10。因此，了解病毒的起源和流行时间对于采取控制措施和预防传播至关重要。
COVID-19疫情何時在全球開始流行？
新冠疫情在全球開始流行的時間點是在2020年3月11日。世界衛生組織（WHO）於該日宣布新冠病毒疫情為全球大流行 27。這意味著病毒已經在全球多個地區傳播，並對各國的公共衛生和經濟產生了重大影響。
根據WHO總幹事於2020年3月11日的媒體簡報，他強調稱COVID-19的大流行這個詞並不是輕率或草率使用的，當這個詞被誤用時會帶來嚴重後果 28。這一事件被視為是全球齊心抗擊疫情的起點，各國相繼實施各種防控措施以應對病毒的傳播。
此外，根據WHO的時間軸，2020年1月4日，WHO在社交媒體上就武漢出現的肺炎病例進行了報告，標誌著新冠病毒的官方關注開始 29。從那時起，全球開始密切關注並回應這一疫情，最終導致了在2020年3月11日被宣布為全球大流行。
總的來說，新冠病毒疫情在2020年3月11日被WHO正式宣布為全球大流行，這標誌著病毒在全球範圍內傳播的開始，引發了全球的關注和應對行動。
新冠病毒在哪裡首次被識別？
新冠病毒（COVID-19）在哪裡首次被識別是一個引人關注的問題。根據來自多個來源的資訊，COVID-19最早是在2019年12月在中國武漢被確認的。它最初是在武漢一個來源不明的肺炎疫情中被鑑定出來的 31。隨後，一系列確診病例開始湧現，迅速影響了當地社區 34。這一發現也得到了中國當局的證實，並被迅速通報。因此，武漢是COVID-19最早被發現和確認的地點。
此外，COVID-19的引起的病毒在2019年12月首次被科學家識別 33。這種病毒在當時的情況下尚未得到有效監測，導致其在武漢引起的疫情傳播迅速 34。該病毒由於其高度傳染性，很快在全球範圍內流行開來。
總結來說，COVID-19最初是在2019年12月在中國武漢被確認的，這一發現對於全球公共衛生產生了深遠的影響。
新冠病毒是如何傳播到其他國家的？
新冠病毒（COVID-19）是通過空氣傳播和人與人之間的近距離接觸等途徑傳播到其他國家的。感染者即使沒有症狀，也有可能具有傳染性 37。病毒傳播的方式主要包括飛沫傳播和空氣氣溶膠傳播，人與人之間的近距離接觸也是主要的傳播途徑。當感染者咳嗽、打嚏或說話時，有可能釋放含有病毒的飛沫，而當他們呼吸時，也有可能釋放病毒氣溶膠 39。此外，病毒還可以通過接觸受污染的表面後再觸摸口鼻等方式進行傳播。
當疫情開始流行時，病毒能夠在各國之間迅速傳播 40。對於病毒傳播速度的精確估計對於預防控制至關重要 38。早期對於病毒傳播的動態特性的研究對於了解其傳播規律和採取相應的防控措施至關重要 42。
因此，預防措施包括保持社交距離、佩戴口罩、勤洗手、通風等，這些都是有效的防止病毒傳播到其他國家的方法。及時採取適當的防護措施，可以降低病毒的傳播風險，保護自己和他人的健康。
