Telehealth on the rise, page-1231

Some are saying the diagnosis number is actually a lot higher than that because they exhibit mild symptom where they recover and aren't diagnosis so the mortality rate is lower than 3%.

How deadly is this coronavirus?

We don’t yet know. However, signs suggest that many people may have had mild cases of the virus and recovered without special treatment.
Very early in this epidemic, it looked like about 20% of cases were severe. People developed acute respiratory distress syndrome (ARDS), which causes tiny air sacs in the lungs to fill with fluid, crowding out air so that not enough oxygen can reach the bloodstream.
As of February 25, 2020, the reported confirmed cases and deaths in China suggest the mortality rate is roughly 3%. It is important to remember that early on in an epidemic there is a “tip of the iceberg” phenomenon where we overestimate more severe cases and mild or asymptomatic cases go unrecognized, so the mortality seems higher than the reality. That may be happening when we speak of up to 3% mortality. By contrast, SARS had a mortality rate of around 10%; the MERS mortality rate is closer to 30% to 40%. There appear to be many more COVID-19 cases confirmed than there were with SARS and MERS.
