Yeah only because it's a novel virus and there is little to no herd immunity. I'm sure flu killed even more its first year when it was novel (since we didn't know about how viruses spread). Once it is no longer novel it will be a seasonal virus likely that kills at similar rates to flu. The real question is, can we stop wearing masks once we've achieve herd immunity? Or is it worth wearing them cradle to grave to reduce seasonal deaths as well?

Herd immunity is something that happens when you have the majority of the population vaccinated. There's no such thing as natural herd immunity. Hopefully, the Covid19 vaccines will be able to destroy a broader variety of the SARS-CoV2 strains than the flu vaccines can. Masks are something we will hopefully have learned to wear forever during the cold season, as they will have a measurable impact on deaths not just from seasonal Covid, but from seasonal flu as well. I believe that the majority of the population will internalize this simple hygienic practice from now on, which would be one silver lining for this pandemic. People in East Asia have learned this habit some time ago, and it has served them well.

  > There's no such thing as natural herd immunity. I disagree. I just think the humans most severely vulnerable to the flu died off during the first few waves. Consider small pox. It was a novel virus for the Native Americans, who had no "natural herd immunity" and they got eviscerated by small pox. Colonists, despite not having vaccines, and despite still being able to get small pox, were not eviscerated since the virus wasn't able to spread and/or kill as well due to their natural immune systems. What do you call this if not "natural herd immunity"? If you kill off all the weak and vulnerable, leaving only survivors and survivors' offspring who are virus-resistant... then you now have "natural herd immunity".

    Herd immunity has a clear meaning: people who are individually vulnerable to a disease being protected from it by virtue of everyone around them being immune. What you're describing is simply a disease running its course and killing everyone who is not naturally immune/resistant or not strong enough to survive despite being sick. There is no herd immunity aspect. At best you could call it natural selection.
