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.
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) 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.
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.
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.
