The English name of the new coronavirus is COVID-19, which is consistent with the WHO naming, and the Chinese name remains unchanged. The new coronavirus is clinically highly infectious, with an insidious early onset and many symptoms similar to the flu, which are easily overlooked. In the late stage of the disease, the new coronavirus causes serious damage to the lungs, resulting in a large number of solid lung changes and a large amount of mucus filling the lungs, making the lungs unable to breathe normally, requiring ventilators for assisted breathing and life support systems for symptomatic treatment, which is very difficult to treat and has a high mortality rate.
