Covid19 Fishbone Diagram

My attempt to create a cause-effect for Covid19. I have included attributes for Material, Measurement, Machine, Methods, Environment, Employees, and Information categories. I am sure I have missed many; this is from the current information I have been able to glean. And most of these causes will need further drill downs for other (root) causes.
Thoughts?
