专家：追溯新冠肺炎“零号病人”难度很大 希望各国携手
<p>我国科学家在国务院资讯办公室4月27日举行的吹风会上表示，追溯新冠肺炎“零号病人”是一个非常难的科学问题，目前中国正在积极推进这项工作，希望各国医学界和科学界携手不断寻找答案。</p><p> 2020年4月9日，工作人员在对武汉返岗的员工进行健康检查。中国科学家4月27日表示，新冠病毒是人造的可能性很低，追溯“零号病人”难度很大，需要全球各国携手展开工作。</p><p>【名词解释】</p><p>“零号病人中国医学科学院病原生物学研究所所长金奇说，</p><p><span word="Finding">Finding</span> <span word="the">the</span> <span word="first">first</span> <span word="infected">infected</span> <span word="case">case</span> <span word="is">is</span> <span word="an">an</span> "<span word="extremely">extremely</span> <span word="difficult">difficult</span> <span word="scientific">scientific</span> <span word="problem">problem</span> <span word="that">that</span> <span word="requires">requires</span> <span word="a">a</span> <span word="great">great</span> <span word="amount">amount</span> <span word="of">of</span> <span word="interdisciplinary">interdisciplinary</span> <span word="research">research</span>". <span word="Scientists">Scientists</span> <span word="have">have</span> <span word="yet">yet</span> <span word="to">to</span> <span word="find">find</span> <span word="patient">patient</span> <span word="zero">zero</span> <span word="for">for</span> <span word="the">the</span> 1918 <span word="influenza">influenza</span> <span word="pandemic">pandemic</span>, <span word="HIV">HIV</span> <span word="or">or</span> <span word="the">the</span> <span word="H">H</span>1<span word="N">N</span>1 <span word="influenza">influenza</span> <span word="in">in</span> 2009.</p><p>追溯“零号病人”是“非常难的科学问题，需要大量的工作，多学科交叉”。1918年大流感、艾滋病以及2009年暴发的<span word="H">H</span>1<span word="N">N</span>1流感等大规模传染病都没有找到明确的“零号病人”。</p><p>中国疾控中心病毒病预防控制所学者刘培培表示，</p><p><span word="The">The</span> <span word="increased">increased</span> <span word="number">number</span> <span word="of">of</span> <span word="people">people</span> <span word="with">with</span> <span word="COVID">COVID</span>-19 <span word="antibodies">antibodies</span>, <span word="as">as</span> <span word="well">well</span> <span word="as">as</span> <span word="the">the</span> <span word="existence">existence</span> <span word="of">of</span> <span word="asymptomatic">asymptomatic</span> <span word="patients">patients</span>, <span word="are">are</span> <span word="two">two</span> <span word="main">main</span> <span word="obstacles">obstacles</span> <span word="in">in</span> <span word="finding">finding</span> <span word="patient">patient</span> <span word="zero">zero</span>.</p><p>有新冠肺炎抗体的人数增加以及无症状感染者的存在是追溯“零号病人”的两个主要障碍。</p>
