I didn't do a survey of Drs and hospitals, but i didn't hear of anything. It's also been reported that the hospitalization rate is much lower with omicron, and anyone who wants to can get vaccinated.
Omicron's hospitalization rate is lower, but transmission is higher.
Transmit to 100 people, with 10% hospitalization => 10 hospitalized
Transmit to 10,000 people, with 1% hospitalization => 100 hospitalized
Just making up numbers, but the point is that a low hospitalization rate could still overwhelm hospitals if the transmission rate is much higher.
