The new coronavirus pneumonia, now also named coronavirus type II, can actually be considered a close relative of SARS, and some people think it is a sister, but it is really not SARS. from the genetic sequence, the new coronavirus and SARS have some differences and do not belong to the same virus. In the early days, some genetic testing institutions diagnosed it as SARS, that is, the virus was not available in the previous gene pool and belonged to a brand new virus, the closest to which was SARS in 2003. therefore, the novel coronavirus might be mistaken for SARS at first, but further examination revealed that there were differences in their genetic sequences. In addition, there are also differences in clinical characteristics between the two, as SARS has a higher morbidity and mortality rate of about 9.6%, i.e., nearly 1 in 10 infected patients fail to be resuscitated. However, the new coronavirus is more contagious than SARS, which lasted less than 10,000 people worldwide and about 8,000-9,000 people. But the number of patients with the new coronavirus pneumonia has exceeded 100,000, so it is far more contagious than SARS. content source: you come to doctor
