I was reading this today about how certain strains are way more lethal than others. While the immunocompromised, elderly, sick and predisposition to complications/death are factors certain to result in a severe reaction to this coronavirus I have wondered what makes it manifest as a mild or annoying cold in some and and an all hands on deck emergency in others.

It's China but there might be something to it. Could explain how some young and otherwise healthy people ended up in the ICU. Does having immunity to a weaker strain confer immunity to this more aggressive strain? I know this was the case with smallpox but this is a different type of pathogen and may behave differently.Li’s team found that some of the most aggressive strains of the virus were able to generate 270 times the viral load as the weakest strains; in addition, the aggressive strains killed the human cells fastest.
