A new type of this virus causing the outbreak is different from the human coronaviruses that have been discovered, and further understanding of the virus requires further scientific research.
It is a type of pathogen that causes respiratory and intestinal diseases. The entire virus particle is like an emperor’s crown, hence the name “coronavirus”. In addition to humans, this virus can infect many mammals such as pigs, cattle, cats, dogs, marten, camels, bats, mice, hedgehogs, and a variety of birds. So far, there were six known human coronaviruses. Four of these coronaviruses are more common in the population and are less pathogenic, generally causing only minor respiratory symptoms similar to the common cold. The other two coronaviruses—Severe Acute Respiratory Syndrome and the Middle East Respiratory Syndrome s, so known as SARS and MERS Coronavirus, can cause severe respiratory diseases.
Interview on the issue of the pathogenic identification of unexplained viral pneumonia epidemic in Wuhan, the reporter interviewed Xu Jianguo, the leader of the preliminary assessment of pathogenic test results and a member of the Chinese Academy of Engineering. He said that the expert group believed that the pathogen of this unexplained case of viral pneumonia was initially determined to be a new coronavirus.
As of 21:00 on January 7, 2020, a new type of coronavirus was detected in the laboratory, and the whole genome sequence of the virus was obtained. A total of 15 positive results of the new type of these viruses were detected by the nucleic acid detection method. From 1 positive patient, The virus was isolated from the samples and showed a typical coronavirus appearance under an electron microscope.The expert group believes that the pathogen of this unexplained case of viral pneumonia was initially determined to be a new type of this virus.
The tissue laboratory used pathogen sequencing for genomic sequencing, nucleic acid detection, and virus isolation on patients’ alveolar lavage fluid, throat swabs, and blood.
To confirm the cause of an epidemic disease, usually the following points must be met:
The expert group believes that the pathogen of this unexplained case of viral pneumonia is initially determined as a new type of coronavirus. The next step is to conduct expert research and judgment in combination with etiology research, epidemiological investigation, and clinical manifestations.
