You might be right but I will speak from experience about here in Sacramento CA.
Took my daughter to the ER 2 weeks ago at 5:30 in the evening on a thursday night.
There were 3 people there. 3. And we’ve been locked down completely because we have no beds available.
Weren’t many in the ER that I was at 3 weeks ago either. Ended up there for kidney stones, so I was in the ER itself as well as the waiting room. They didn’t let me sit in the waiting area very long - two other patients there, one was in the same area as me for maybe 1 minute max, they were triaging people fast to get them isolated into ER rooms.
Once in the ER I noted several rooms with patients, but none that I heard were for covid, though I only heard one diagnosis other than mine, which was a patient that had a gall bladder issue. I heard very little other meaningful chatter, but did get wheeled through twice (on my way to and back from the CT scanner). They did not seem very busy though as I got better attention then I ever had previously in several visits in years past at this same ER. All in all, they either did not have a large influx of patients, did not have staffing issues, or both.
I was at Kaiser South Sacramento this morning dropping off some stuff and when I swung by the ER it had maybe six people waiting and that was it. No crowd to be seen at all.
