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
