If Covid had the same mortality rate as SARS-1 and affected younger people in the same way. it doesn't bear thinking about.

SARS-1 didn't carry the same 'load' when people sneezed, coughed or breathed out and they couldn't infect other people until after they had symptoms. The biggest problem with Covid is how fast it spreads, faster than flu.

I'd be interested to know if there is a correlation between how fast a corona can spread and its' mortality rate. Would it be possible to have a fast spreading corona variant that kills a lot more people? A high load implies that it concentrates less deeply within the lungs, so hopefully not.
