Why? Mortality rate and r0 are both less than SARS. Mortality rate will likely be less than 1% when all things are said and done. Typically people begin recovery by day 11 after onset of symptoms. Seasonal influenza is 14 days.

The new coronavirus isn’t believed to be an airborne virus, like measles or smallpox, that can circulate through the air. “If you have an infected person in the front of the plane, for instance, and you’re in the back of the plane, your risk is close to zero simply because the area of exposure is thought to be roughly six feet from the infected person,” said Chiu.
“I believe that the actual calculated death rates will go down over time, perhaps to less than 1 percent” said Chiu.
After day 11, most patients who survive are on their way to recovery.
