Yeah. There’s also things like how easy it is for your body to detect and kill (maybe infection rate is strongly sublinear in dose because of this), where the pathogen lands (if a tiny target needs to be hit and pathogen usually hits you in a single localized area, number of exposures may be more important than dose), whether a substrain is already adapted to by your immune system, etc. Nothing too crazy can be true here because of empirics but certainly mildly crazy things may be.
