據武漢市新型冠狀病毒感染的肺炎疫情防控指揮部消息：

The local government of Wuhan announced that all public transportation in the city — local buses, long-distance buses, subway and ferry — will be temporarily closed starting at 10am on Thursday.
自2020年1月23日10時起，武漢全市城市公交、地鐵、輪渡、長途客運暫停運營。

All flights and trains scheduled to depart from Wuhan also will be temporarily canceled to reduce the risk of spreading the new virus, the government said.
機場、火車站離漢通道暫時關閉，以遏制疫情蔓延。

Residents in Wuhan were suggested not to leave the city if there is no particular reason, according to the announcement.
無特殊原因，市民不要離開武漢。

最長潛伏期約14天

國家衛生健康委員會1月22日晚發布了《新型冠狀病毒感染的肺炎防控方案(第二版)》。

Based on the current knowledge, the incubation period of the virus can be as long as about 14 days, according to a prevention and control plan released Wednesday by the NHC.
方案指出，基于目前對新型冠狀病毒感染的肺炎的認識，疾病的潛伏期最長約為14天。

The outbreak of viral pneumonia has a relatively low chance of infecting young children based on current understanding of the pathogen, Gao Fu, director of the Chinese Center for Disease Control and Prevention, said at a news briefing in Beijing on Wednesday.
中國科學院院士、中國疾病預防控制中心主任高福1月22日在國新辦發布會上表示，根據目前的流行病學認知，新型冠狀病毒對于兒童等年紀小的人不易感。

Wild animals sold at a seafood market in Wuhan could be the source of the outbreak, Gao said, adding that Chinese scientists have cultured, isolated and analyzed the genetic makeup of the microorganism, which is a key step in understanding the new strain of coronavirus and producing a vaccine.
新型冠狀病毒的來源是武漢一家海鮮市場銷售的野生動物。我國科學家已經培養、分離并分析了這種微生物的基因構成，這是了解新型冠狀病毒并研制疫苗的關鍵步驟。

The exact animal carrier is still being investigated even as the virus undergoes adaptations and mutations, he said, adding that, "It is like a cat-and-mouse game. Our understanding of the virus will deepen with further research."
這個野生動物的病毒也在逐漸適應和變異，具體的病毒宿主還在研究中。病毒和人類的關系就像貓鼠游戲，在互相適應。還是需要隨著時間的推移，對它進行進一步研究。
