As the wave of omicron coronavirus subvariant BA.5 continues to flood the US, daily COVID-19 hospitalizations are four times higher than four months ago, according to the latest data from the Centers for Disease Control and Prevention.

The data reflects the high ongoing transmission of coronavirus subvariants adept at evading fading immune responses in a population that is largely unboosted.

In early April, as the US fell into a brief pandemic lull in the wake of the towering BA.1 omicron wave, the seven-day rolling average for new hospitalizations sunk to around 1,420 per day nationwide. Now, after waves of subvariants BA. 2, BA.2.12.1, and the current BA.5, hospitalizations have floated back up. The current seven-day rolling average is nearing 6,300. Overall, more than 37,000 people in the US are currently hospitalized with COVID-19.
