原標(biāo)題：不信情報界結(jié)論，特朗普堅稱病毒源于武漢實驗室？美媒披露內(nèi)幕

隨著疫情席卷全球，新冠病毒起源無疑成為當(dāng)前輿論最關(guān)注的話題之一，而美國某些政客卻在一味散布“武漢實驗室起源論”。

當(dāng)?shù)貢r間4月30日，美國國家情報局局長辦公室在其官網(wǎng)上發(fā)布聲明，明確表示情報界同意科學(xué)界的廣泛共識，即新冠病毒不是人造的，也未經(jīng)過基因改造。

但在當(dāng)天稍晚舉行的白宮發(fā)布會上，特朗普卻仍堅持對外宣稱，他有證據(jù)認(rèn)為新冠病毒與武漢的實驗室有關(guān)。但當(dāng)記者隨后追問他是基于什么證據(jù)作出這一論斷時，特朗普卻拒絕告知。

不少外媒紛紛對“特朗普給不出證據(jù)”這一點進行報道。

美國CNBC稱，特朗普懷疑新冠肺炎疫情來自中國實驗室，但未提供證據(jù)。（特朗普為何不公開美國生化基地為何關(guān)閉呢？從武漢運回去的那5個軍人是死是活呢？如果是瘧疾，用得著派生化專用集裝箱飛機接回去嗎？）

美國CNN指出，特朗普與國際社會“唱反調(diào)”，聲稱他已經(jīng)看到證據(jù)讓他“高度相信”新冠病毒起源于中國武漢的一個實驗室，但拒絕提供任何細(xì)節(jié)以支持其主張。

美國《商業(yè)內(nèi)幕》網(wǎng)站表示，特朗普聲稱他有證據(jù)表明新冠病毒源于武漢的實驗室，但他“不被允許告知”是何證據(jù)。

A statement from U.S。 intelligence agencies debunked conspiracy theories about the origin of the novel coronavirus， concluding that it was “not manmade or genetically modified?！?

The Office of the Director of National Intelligence released the statement Thursday。 The conclusions were consistent with a worldwide scientific consensus that includes the World Health Organization （WHO）。

The announcement came as the Trump administration continues to push an unproven allegation that the virus may have escaped from a Chinese government research lab in Wuhan， the then epicenter of the outbreak in China。

Trump claimed later on Thursday that he has reason showing that the coronavirus originated from the lab in China， but provided no evidence。

同日，《紐約時報》刊發(fā)了一篇題為《特朗普政府官員據(jù)稱向情報人員施壓，讓其將病毒與實驗室聯(lián)系起來》的文章。文章援引多名現(xiàn)任和前任美國官員的話稱，特朗普政府高級官員要求美國情報機構(gòu)尋找證據(jù)，用以支持武漢實驗室是新冠病毒源頭這一“毫無事實根據(jù)的理論”。而美國國務(wù)卿、前中情局局長蓬佩奧，就是帶頭推動這一施壓行動的人。

報道稱，一些美國情報分析人士曾表達(dá)過他們對此行動的擔(dān)憂，稱來自美政府高官的壓力會扭曲對病毒（起源）的評估，并會被作為針對中國的“政治武器”。

中情局分析人員多次表示他們沒有發(fā)現(xiàn)任何證據(jù)支持“武漢實驗室病毒起源論”，情報人員也指出，病毒起源“從根本上說，是科學(xué)問題，不能輕易用間諜的手段解決?！?

報道還指出，任何將疫情發(fā)生歸咎于中國機構(gòu)的情報報告，都“可能在未來幾年嚴(yán)重?fù)p害與中國的關(guān)系”。特朗普政府官員可能會利用這種結(jié)論，在即使無法確定病毒來源的情況下，驅(qū)使其他國家就新冠肺炎死亡事件公開追責(zé)中國。

Meanwhile， some U.S。 intelligence analysts have expressed concern that pressure from senior Trump administration officials to link the coronavirus with a Chinese lab will distort assessments about the virus and could be used as a political weapon， the New York Times said in a report on Thursday。

According to the report， C.I.A。 analysts have repeatedly told Trump aides that they “did not have the evidence to support any one theory [linking the virus to Chinese labs]?！?Besides， U.S。 intelligence officials have noticed continuously that the origins of the virus “is fundamentally a scientific question that cannot be solved easily by spycraft?！?

The report also pointed out that any American intelligence report blaming a Chinese institution for the outbreak “could significantly harm relations with China for years to come，” for fear that  Trump administration officials could “use it to try to prod other nations to publicly hold China accountable for coronavirus deaths” even when the exact origins cannot be determined。

針對“新冠病毒源于武漢病毒研究所泄漏”的謠言，該所研究員、武漢國家生物安全實驗室主任袁志明日前在接受CGTN專訪時表示，病毒絕不可能從其所在的研究所泄漏。

包括有“病毒獵手”之稱的美國哥倫比亞大學(xué)教授利普金在內(nèi)的多國專家，也都多次表示病毒起源于動物，不可能是人為制造，且目前也沒有任何證據(jù)證明病毒是從實驗室漏出的。

新冠病毒源于武漢實驗室？國際社會強烈駁斥：無稽之談！

The director of one of the Chinese labs in question rejected the idea in an interview with CGTN。 Yuan Zhiming of the Wuhan National Biosafety Laboratory told CGTN that： “There is absolutely no way that the virus originated from our institute?！?

In correspondence sent to one of world‘s leading science journals， Nature Medicine， leading virologists from the U.S。， the UK and Australia expressed skepticism of the genetic manipulation theory。 Having analyzed the pathogen’s genome， they said： “We do not believe that any type of laboratory based-scenario is plausible?！?

與此同時，科學(xué)界一直在進行病毒溯源的科學(xué)研究。多國科研人員表示，當(dāng)?shù)匦鹿诜窝滓咔椴⒎怯芍袊斎氲牟±隆?

法國科學(xué)家近日進行的一項研究也顯示，法國新冠肺炎疫情并非由中國或意大利的輸入病例引起的，而是來自一種在當(dāng)?shù)貍鞑サ膩碓床幻鞫局?。該研究由巴斯德研究所研究人員完成，并于4月24日以預(yù)發(fā)表發(fā)布在bioRxiv.org網(wǎng)站上。

研究人員對1月24日至3月24日期間在法國收集的97份病毒樣本進行了基因測序與比對，發(fā)現(xiàn)法國流行的新冠病毒屬于不同的分支，和來自中國與意大利的輸入病例都不相同。

A genetic study done by French scientists revealed that the COVID-19 outbreak in France was caused by a locally circulating strain with unknown origin， rather than cases imported from China or Italy。

The pre-print study， entitled “Introductions and early spread of SARS-CoV-2 in France”， was done by researchers from the Pasteur Institute in Paris， a research center at the forefront against infectious disease， and published on biorxiv.org on April 24。

The researchers sequenced 97 genomes from samples collected among infected cases in France between January 24 to March 24， and found that the dominant strain of the outbreak in the country was linked to a genetic group， or clade G， that was not from China or Italy。

法國現(xiàn)今流行的病毒樣本中，最早一個具有代表性的樣本是2月19日從一名患者身上采集的，該患者沒有國內(nèi)外旅行史，也沒有和海外歸國的旅行者接觸過。該患者于2月25日去世，隨后法國出現(xiàn)大規(guī)模疫情潮。

研究人員由此推斷，疫情早在2月份就已開始在法國悄然流行，且大部分患者無癥狀或有輕癥。

One of the earliest representatives of the French clade was sampled on February 19 from a patient who had no travel history and no contact with travelers returning from overseas。 The patient passed away on February 25 and then came a wave of outbreaks in France。

“As the earliest representative of clade G had no history of travel or contact with returning travelers， we can infer that the virus was silently circulating in France in February， a scenario compatible with the large proportion of mild or asymptomatic diseases， and observations in other European countries?！?

加拿大媒體也報道稱，該國早期病例并非來自中國。

加拿大《全國郵報》4月30日報道稱，根據(jù)該國四個新冠肺炎病例數(shù)最多省份的相關(guān)數(shù)據(jù)，加拿大早期的新冠病毒感染病例來自美國，而非中國。Data from Canada‘s largest provinces show it was American travelers， not Chinese， who brought the novel coronavirus to Canadian shores， according to the National Post Friday。

The National Post in Canada asked for data on the origins of travel-related cases in four provinces that have seen the majority of Canada‘s COVID-19 cases。
