This is a useful analogy from @pluralistic : COVID was an opportunistic infection. It killed disproportionately people suffering from other pathologies, and we, collectively, struggled to attribute the deaths of COVID patients to COVID itself rather than those other pathologies. Eventually there was a sort of agreement that excess mortality is a reasonable way to measure COVID's impact.
