Observation by Henry Lahore, Boeing comany Systems Engineer (retired) and Founder of Vitamin D Life
This is a good first step by one systems thinker

This model might need to consider many other parameters - such as

  • Skin Color
  • Season
  • Cormodidities (Hypertension, Diabetes, etc)
  • Asymptomatic, Symptoms, Long Haul
  • Evolution of the virus
  • Mask use which benefits the wearer
  • Limitation of resources: testing, hospital, vaccination,
  • Different age groups: aged, children
  • Superspreaders

Next steps

  • Decide where additional parameters might go on the diagram
  • Make next version
  • Assign some importance to each node and link
    • Example: larger font size or line width
  • Make a simplified model for people
