Is the new crown infected with SARS serious

COVID-19 infection is more infectious than SARS. COVID-19 infection has an incubation period of 1-14 days. It is asymptomatic during the incubation period and is not easy to be detected, but it is infectious and easy to cause large-scale transmission. However, the severity and progression speed of COVID-19 infection are generally better than SARS. Active treatment generally has no sequelae.
