Mister Way! I love the color matching, and being in QA can't resist good math... Actually I did more or less the same math weeks ago leading to the same or less ideas.

Well your advice still is a serious one and what I try to do as much as possible. Following this I reduced my social contacts from over 80 people a day to less than 8 on high days, if I'm patient 0 I can track my spreading quicker than a Bluetooth app would.

Yet, data is flawed. The sample being 10e-16 of the actual population, it really gives any scenario awfull odds in terms of trust. We still have no clue of the R0 only figures givent to us by people without that much data either (and which data sets are they using for that is important too, just in France governemental health organisations show differences in the figures going up to 50%.) Just yesterday in serious news sources, R0 was between 2.2 and 7.6, that's a huge difference.

Anyways, while masks, gloves and self insulation is indeed a really good plan to lower the spread, it has 2 flows : - not everyone can shelter not is educated enough to really understand what's at stake. I think about a few really skilled shop floor workers I highly respect here, but grasping the concepts underlying a spread is over their heads... - your scenario assume humans as the only vector... Erm... Mosquitoes start hatching here...

Anyways great job really
