Hospitals across California have all but run out of intensive care beds for COVID-19 patients, ambulances are backing up outside emergency rooms, and tents for triaging the sick are going up as the nation’s most populous state emerges as the latest epicenter of the U.S. outbreak. On Thursday, California reported a staggering 52,000 new cases in a single day — equal to what the entire U.S. was averaging in mid-October — and a one-day record of 379 deaths. More than 16,000 people are in the hospital with the coronavirus across the state, more than triple the number a month ago.
