Review all example of usage: Epidemic as example of usage for 'Material entity'

While inspecting the BFO current examples of usage, I came across the following:

epidemic as example of usage for Material.

I presume this may stem from the reasoning that epidemic may be understood as 'a wave of disease' and since several 'example of usage' relate to some sort of 'wave' (energy wave, sea wave), the term may have been dumped there but it does not feel right.

As a side note, Infectious Disease Ontology (which uses BFO1.1) cast 'infection disease epidemic' as a process with the following definition: "A process of infectious disease realizations and for which there is a statistically significant increase in the infectious disease incidence of a population."

Either this particular is incorrect and should be removed or it should be documented further, expanding on the reason (maybe because casting epidemic as material or storm as material allows those things to bear qualities)

BFO should have the rule that for any example of usage, a subtype could be directly asserted under the class it is suppose to illustrate. "epidemic is_a material entity', 'tornado is_a material entity', hurricane is_a material entity'
