Coronavirus Update (Live): 19,358,362 Cases and 719,561 Deaths from COVID-19 Virus Pandemic - Worldometer
Or the New York Times, which has the 14 day average.
You questioned these estimates before, but looking at the real figures shows more than 1166. None of us can predict the future, but yes, it's realistic.
Yesterday, we lost 1203 Americans (that we know of, a couple of states are having trouble updating their numbers).
Two days ago, it was 1319. For days, recently, it was around 1500.
The only time it drops below 1200 of late, is on Sundays.
I'd go by the CDC figures posted on Worldometer, not what the BBC's interpretation is. We are over 1000 deaths daily for more than 2 weeks, there's no sign we're changing our behavior. In fact, we're opening up schools (maskless in some places) and teachers are going home sick, one has died (at least) since yesterday.
Look for our deaths to hover around 1200-1300 for quite some time. Hopefully, the news will scare a few more people into wearing masks or staying home aside from work and essential shopping.
We have a lot of people out vacationing and driving all over the nation, as well. I don't see the numbers coming down by much - sure do hope I'm wrong. But 1166 deaths a day?
YES, it's realistic.
