oh of course. there are people conditioned not to seek treatment because they know they can't afford it and there are people who think it's a hoax or they're somehow supporting trump by not getting tested or treated right up until they die. reported cases and deaths are almost certainly being way undercounted and government officials and media propagandists suggesting that we are actually OVER counting are projecting
The scary thing is that tweet could be correct even with the global context. At least if you believe social distancing and masks makes any difference, the northeast adopted those measures way earlier and has had better overall adoption than elsewhere.. But testing was still critically behind, and there were too significant of delays in acting even in places like NY.
Btw. Expect to see a ton of revision of mortality figures upwards after we get this under control. Some of the epidemiologists I know have highlighted the spikes in "flu like" deaths etc, especially before / (still in some places) tests weren't widely available.
