For those quoting different mortality rates for this virus, one of the main doctors working on this in the US explained that people with already existing lung issues were much more vulnerable to this, so the higher the smoking rate in a country, the higher the mortality rate will be. This is another reason it affects the elderly more, since their generations did more smoking than the younger generations.
What I am still wondering about, and need to look into for people I know, is why diabetics are also more in danger from this virus.
