What's the difference between novel coronavirus and SARS virus? First of all, the main difference between SARS and novel coronavirus lies in its spreading ability and fatality rate. Both viruses are transmitted through the respiratory tract. Because novel coronavirus has a longer incubation period, its transmission ability is stronger than that of SARS. If you suspect that you have symptoms, you must isolate them in time and support the treatment after diagnosis. In terms of mortality, the mortality rate in novel coronavirus is lower than that of SARS. At present, the number of infected people is 79,972, and the cumulative death toll is 2,873, which is a low death rate of less than 4%.
20 19 novel coronavirus was officially named as 20 19-nCoV by the world health organization on June 65438+ 10/2, 2020. Coronavirus is a virus that is known to cause colds and more serious diseases, such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). Novel coronavirus is a kind of novel coronavirus that has never been found in human body. Common symptoms of people infected with coronavirus include respiratory symptoms, fever, cough, shortness of breath and dyspnea. In more serious cases, infection can lead to pneumonia, severe acute respiratory syndrome, renal failure and even death. At present, there is no specific treatment for diseases caused by novel coronavirus. However, many symptoms can be treated, so it should be treated according to the patient's clinical situation.
On April 16, 2003, the World Health Organization announced that the variant of coronavirus was officially confirmed as the pathogen leading to atypical pneumonia. SARS virus belongs to Coronaviridae, Coronaviridae and Coronaviridae. It belongs to subclass B coronavirus. Virus particles are mostly round, surrounded by capsule and coronal fibrils. They are distributed in the cytoplasm and are round. The virus diameter is between 80- 120nm. In Guangzhou and Beijing, a large number of virus particles were found in Vero-E6 cells infected by autopsy lung tissue samples, most of which were round and about 80 nm in diameter. Virus particles are mainly distributed in the endoplasmic reticulum pool of cytoplasm and inside and outside cytoplasmic vacuoles, and gather in piles. Cells infected with the virus can see endoplasmic reticulum expansion, mitochondria swelling, cr dissolution, nuclear chromatin concentration and edge aggregation.
