I assume that number is global? There's no way the US is anywhere near 100 million. And those numbers are all region specific. There are plenty of big cities in the US that have seen very little community spread. No...that would be the United States alone. The CDC thinks that only about 1 in 7 cases are actually getting reported. I don't think it is that farfetched from what I have seen. They reported that belief way back in June and they still believe that to be the case now. You have to consider the asymptomatic rate, people simply refusing to get tested, those are not severe enough to get a test, and people they know are probably positive but they just tell to stay home. The later of which I am mostly referring to when one family member tests positive, but they will tell the rest of the family to just quarantine like they have to anyway. I have known 6 or so households where others got sick, but it wasn't severe so there wasn't really a need to test to prove it. I would guess we are somewhere between 70mil-100mil, it is waaaaaay more than the 13.5mil that are official. The people going under the radar will probably become an even bigger problem as we sneak into flu season. Getting sick in July is weird, but as we enter winter people probably won't be running to get a test for mild symptoms.
