Some MYTHS about COVID-19: - that herd immunity is inevitable - that epidemiologists love lockdowns - that it is less lethal than flu - that we can easily protect "the vulnerable" - that we can "let it rip" without cost

Just so I understand you correctly. Say new cases of Covid fall to very low levels because most people have immunity, say because of a vaccine. Would you describe that as endemic disease? It's in this context that I have heard the term herd immunity used
-
No, that would be an accurate description of herd immunity

Depends on discipline, but please clarify, otherwise this is just playing with words not explaining the science - at some point the susceptible population will be sufficiently small that transmission slows, agreed? Whether we call this herd immunity or endemicity is secondary.

It may slow to some extent, but previous pandemics have ended with (e.g. influenza) large seasonal outbreaks, or ongoing transmission (e.g. Zika) or in quite a number of other ways (HIV, Ebola, etc). Endemic disease is very much not herd immunity

Seems like we are getting close to a semantic argument, but your definition is not universally sharedhttps://twitter.com/BallouxFrancois/status/1312701821685772290 …
