This is total and complete fear mongering and it is frankly irresponsible.
First, the WHO has just said the virus is of very low risk to children, for whatever reason people under 19 have had few cases. Second, it is only of high risk to the elderly and those with preexisting conditions. Third, the crude fatality rate (which is what you are calling the "death rate") is not the mortality rate of the virus, because there are likely thousands if not hundreds of thousands of undetected cases where cold symptoms are experienced and the patient recovers. Fourth, I have yet to see any study where the comorbidity with smoking is examined. Virtually everyone in China smokes, which may also be why the CFR is higher in men (more smokers), and higher in China and Italy than, ultimately, the UK, Iran, or the US. There are responsible medical scientists suggesting that possible link to worse outcomes.
Read the WHO report just out on China containment. Or just read. But scaring people on this website with tales of 10 million dead is the height of irresponsible online activity, in my view.
Read more. Know more. Or speak less.
