The news and literature on covid 19 point out the following:
1. The spread follows the Pareto principle that only 10 to 20% of those infected were responsible for the spread;
2. That transmission occurred in enclosed places like bars, restaurants, choirs, places of worship, but none occurred in theaters libraries or theme parks.
3. In factories, spread took place where there is refrigeration as in meat packing plants dairies where it is cold.
