Covid-19 Infection Spread Excel Spreadsheet

Click on picture below  to download version 2 of this the Excel File. This shows how the Herd immunity works if the infection is allowed to let rip.  Not something that is going to be allowed to happen.

With this sheet one can change te rates at different times t see what difference it makes.

   ( Version 1 ).  Much better version coming soon. 

My favorite YouTube Video so far on this subject is this one:  which explains in a very simple and easily done way how to estimate how many infested people there are in your area.  The comments are also  interesting icluding one from a person in Shanghai where they are over it and getting back to normal.

Also crucially with that video are links to very comprehensive sources of research information.   ( Research   and  Why you Must Act Now )
