I see two categories listed on those graphs symptomatic and critical. Where is the asymptomatic portion of this?

Really makes you wonder what is at play here that seems to provide a good chunk of the population virtual immunity

I personally know three people who tested positive, all 3 are middle aged (45-55). One only lost sense of smell; one had mild symptoms for 2-3 days plus loss of taste and smell, and one had typical symptoms of cough, fever, and being tired. It is a mixed bag with how this virus affects people.

I'm thinking that the cross reactivity of immune responses to other coronaviruses have to be playing a part. Disclaimer: I have no medical background but I stayed at a Holiday Inn last night and this seems intuitive given the current dataset.

To piggy back off keegan, no matter the country, area, state, wearing masks, not wearing masks, lockdowns, no lockdowns, etc. It seems to follow the same pattern everywhere. A really quick spike/surge (we are going through that in texas), then a steady fall afterwards long before what would be perceived as herd immunity, which indicates a very high percentage has some kind of natural immunity / defense for this. Yes, extra social distancing measures and masks might help the fall too, but I think it goes well beyond that.

I've been convinced for a long time that herd immunity will beat the vaccine, although I'll gladly take the vaccine if possible. Particularly if it prevents future waves assuming natural immunity might not last forever. To me, that's what good the vaccine will do. Not to really help much in this run of the disease, but to prevent it from flaring up in the future.

There seems to be something with blood type.

I think that plays a huge factor as well.

And that's the three that knew they had it. For those three there are 4 or so out there with no symptoms who didn't even know they had the disease, per this study.

Hope so. My parents are both over 70 and have multiple underlying conditions (and one having surgery early next week), so it's been tough not to be able to be around them more.

Have no idea if the science checks out on this, but would it make sense that people who are asymptomatic would spread a version that's also asymptomatic? It seems like these bulk testing situations with pro and college teams are turning up a number of positives but basically no one actually sick.

I also think the evidence is becoming clearer that asymptomatic people do not spread the disease.
