Don't try arguing with the flu bros. They'll figure it out in 3 to four weeks.
The number of confirmed cases has risen by an average of 31% each day since February 28, and by an average of 578% per week. In just the last 7 days, the number of confirmed cases in the US has increased by 834%.
If this rate of growth continues, then just 4 weeks from today there will be almost 15,000,000 confirmed cases, with an increase of over 2,000,000 from the day before. If they don't get it then, then they never will.
It's the eighth wonder of the world, compounded interest, applied to the Coronavirus.
Of course, if the social distancing being done now is effective, then these numbers will be WAY lower. And they'll claim "See! It was all overblown."
