Although both the novel coronavirus and SARS are infectious diseases, the types of viruses are not the same. The symptoms of the new coronavirus and SARS are similar, but SARS has a higher fatality rate. The mortality rate is close to 10%, and many patients have severe pneumonia, which is characterized by the so-called large white lung, very heavy respiratory distress, and rapid onset, generally entering the peak of the disease in 2-3 days. Although the new coronavirus is also more harmful to the body, but the death rate is slower, and the infection will be suppressed by some drugs to suppress the attack of the virus. It has been found that the new coronavirus is more infectious than SARS and spreads more rapidly.
