自2020年1月23日10时起，武汉全市城市公交、地铁、轮渡、长途客运暂停运营。

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.

最长潜伏期约14天

国家卫生健康委员会1月22日晚发布了《新型冠状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，基于目前对新型冠状病毒感染的肺炎的认识，疾病的潜伏期最长约为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.
中国科学院院士、中国疾病预防控制中心主任高福1月22日在国新办发布会上表示，根据目前的流行病学认知，新型冠状病毒对于儿童等年纪小的人不易感。

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.
新型冠状病毒的来源是武汉一家海鲜市场销售的野生动物。我国科学家已经培养、分离并分析了这种微生物的基因构成，这是了解新型冠状病毒并研制疫苗的关键步骤。

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."
这个野生动物的病毒也在逐渐适应和变异，具体的病毒宿主还在研究中。病毒和人类的关系就像猫鼠游戏，在互相适应。还是需要随着时间的推移，对它进行进一步研究。
