Corona virus, China major city lockdowns, etc.

Maybe we could think of it in another way: COVID-19 has been popular all over the world earlier. More than 20 million people have been infected in the US in 2019, but most have recovered on their own. Maybe when calculating the severity and mortality of COVID-19, the population base should be set to 30-50 million. In this way, the severity and mortality of COVID-19 is close to severe influenza. But COVID-19, as a newly born virus, is more contagious than influenza.

Edit:
IMO, the situation in China, Italy, and Spain are particularly serious is because that panic has caused a large number of people to flock to the hospital, which not only caused the run-up of medical resources, but also caused a large number of doctors and nurses to be infected. As a result, these doctors and nurses began to infect a large number of people who came to the hospital for testing.

When the rumors began to spread, hundreds of thousands of people in Wuhan flocked to the hospital at the same time, causing more than 3,000 doctors and nurses to be infected, as a result, they may have infected 30,000 to 60,000 people. In Italy, more than 6,000 doctors and nurses were infected, as a result, they may have infected 60,000 to 120,000 people.
