武漢不明原因的病毒性肺炎疫情病原體初步判定為新型冠狀病毒就武汉不明原因的病毒性肺炎疫情病原学鉴定进展

就武汉不明原因的病毒性肺炎疫情病原学鉴定进展问题,记者今天从病原检测结果初步评估专家组了解到,截至2020年1月7日21时,实验室检出一种新型冠状病毒,获得该病毒的全基因组序列,经核酸检测方法共检出新型冠状病毒阳性结果15例,从1例阳性病人样本中分离出该病毒,电镜下呈现典型的冠状病毒形态。

As for the progress of etiological identification of viral pneumonia with unknown causes in Wuhan, the reporter learned today from the preliminary assessment expert group on the results of pathogen detection that as of January 7,2020, a new type of coronavirus had been detected in the laboratory, and the whole genome of the virus had been obtained.

组织实验室采用基因组测序、核酸检测、病毒分离等方法对病人的肺泡灌洗液、咽拭子、血液等样本进行病原学检测。

The tissue laboratory used genome sequencing, nucleic acid detection, virus isolation and other methods to detect the etiology of the patient's alveolar lavage fluid, pharyngeal swab, blood and other samples.

(3)分离的病原感染宿主动物后可引起相同的疾病症状。而病人恢复期血清中该病原的抗体滴度有4倍升高,可帮助确定病原。

(3) Isolated pathogens can cause the same symptoms after infecting the host animal. And the antibody titer of the pathogen in the serum of the patient during convalescence increased by 4 times, which can help to determine the pathogen.

从病人中发现病原的核酸、基因组和抗体证据,短期内可以完成。病原的分离和致病性鉴定等科学研究,则需要数周时间。针对一种新发病原体的特效药物和疫苗研发可能需要数年时间来完成。专家组认为,本次不明原因的病毒性肺炎病例的病原体初步判定为新型冠状病毒,下一步需结合病原学研究、流行病学调查和临床表现进行专家研判。

the discovery of evidence of pathogenic nucleic acids, genomes, and antibodies from patients can be completed in the short term. Scientific studies such as pathogen isolation and pathogenicity identification take weeks. The development of specific drugs and vaccines for a new pathogen may take years to complete. The expert group believes that the pathogen of this unexplained case of viral pneumonia is initially identified as a new type of coronavirus, the next step needs to be combined with etiological research, epidemiological investigation and clinical manifestations of expert study.

冠状病毒是一类主要引起呼吸道、肠道疾病的病原体。这类病毒颗粒的表面有许多规则排列的突起,整个病毒颗粒就像一顶帝王的皇冠,因此得名“冠状病毒”。冠状病毒除人类以外,还可感染猪、牛、猫、犬、貂、骆驼、蝙蝠、老鼠、刺猬等多种哺乳动物以及多种鸟类。目前为止,已知的人类冠状病毒共有六种。其中四种冠状病毒在人群中较为常见,致病性较低,一般仅引起类似普通感冒的轻微呼吸道症状。另外两种冠状病毒——严重急性呼吸综合征冠状病毒和中东呼吸综合征冠状病毒,也就是我们简称的SARS冠状病毒和MERS冠状病毒,可引起严重的呼吸系统疾病。引起此次疫情的新型冠状病毒不同于已发现的人类冠状病毒,对该病毒的深入了解需要进一步科学研究。

coronavirus is a class of pathogens that mainly cause respiratory tract and intestinal diseases. The surface of these virus particles has many regularly arranged protrusions, and the entire virus particle is like a crown of emperors, hence the name \"coronavirus \". In addition to humans, coronaviruses can also infect pigs, cattle, cats, dogs, minks, camels, bats, mice, hedgehogs and a variety of birds. So far, there are six known human coronaviruses. Four of the coronaviruses are more common in the population and are less pathogenic, generally causing only mild respiratory symptoms similar to the common cold. Two other coronaviruses, the severe acute respiratory syndrome coronavirus and the Middle Eastern respiratory syndrome coronavirus, the SARS coronavirus and the MERS coronavirus, as we call them, can cause severe respiratory diseases. The new type of coronavirus that caused the epidemic is different from the human coronavirus that needs further scientific research.
