20% Positivity test rate
1 in 5 coronavirus tests are positive in L.A. County, pointing to tough weeks ahead

About 1 in 5 coronavirus tests performed daily in Los Angeles County are coming back positive, an astounding rate that officials say illustrates the pandemic’s continued rampage through the region and foreshadows grave consequences for an already beleaguered healthcare system.
Around Nov. 1, roughly the starting point of the current coronavirus wave, only about 1 of every 25 tests confirmed an infection.
Officials warn that the arithmetic is as grim as it is simple. When such a high proportion of people are testing positive and tens of thousands of tests are conducted a day, case counts end up staggeringly high. And when community transmission is this prolific, officials warn that activities that seemed mundane months ago now carry
a higher risk of infection than ever.
L.A. County on Thursday recorded its fourth-highest number of coronavirus cases in a single day, according to a Times tally of local health jurisdictions, possibly an early sign of the surge of new cases connected to Christmas gatherings.
On Thursday, 18,764 new cases were reported, well above the daily average over the last week, which was about 14,000. There were 205 COVID-19 deaths, according to The Times’ tally, the sixth-highest single-day death toll. L.A. County is now averaging 171 deaths a day over the past week.
These figures “can be numbing,” Mayor Eric Garcetti acknowledged, but he emphasized that the number of hospitalizations represents a threefold increase from a month ago and the most in a single day since the pandemic began.
California posted at least
37,000 new coronavirus cases Thursday, continuing a trend over the last week in which the statewide daily total has flattened at about 39,000. That’s modestly less than the peak in mid-December, when California was reporting as many as 45,000 new cases a day.
Garcetti, however, cautioned against viewing this leveling out as a “plateau that will automatically come down.”
“It’s my belief this is just a pause before a new peak,” he said.
Experts fear that the counts will begin to systematically rise by the end of the week, as people who were
exposed to the virus over Christmas or New Year’s begin to fall ill and get tested. Though many of those infected may experience only minor symptoms, or none at all, officials have long warned that the daily caseload is only the start of a disastrous domino effect.
A certain proportion of those testing positive — state officials have estimated about 12% — will fall ill enough to require hospitalization in the weeks following their exposure. And 12% of those people will worsen to the point they need intensive care. Some won’t survive.
High numbers of cases on the front end will invariably lead to more suffering and grief down the line.
“If the transmission within Los Angeles County, as we suspect it probably did, increased over the holidays, then we will experience an increase in hospitalizations,” Dr. Christina Ghaly, the county’s director of health services, said this week.
Conditions across L.A. County’s healthcare system are already bleak.
Hospitals are
reporting significant shortages of staff because so many employees are out sick or in quarantine. Officials have
warned they’re running short of available ambulances, with emergency rooms so full that transport vehicles must wait hours to drop off patients — forcing those calling 911
to wait even longer for paramedics and emergency medical technicians to arrive.
Even
supplies of lifesaving oxygen have been stretched thin both by overwhelming need and problems with aging hospital infrastructures.
L.A. County Emergency Medical Services Agency Director Cathy Chidester said Thursday that there continues to be a shortage of oxygen canisters that are needed to send recovering COVID-19 patients home from the hospital, which would help free up beds.
Some hospitals’ aging oxygen distribution systems, which began to fail recently in a number of hospitals due to age and freezing amid the unprecedented demand for oxygen, have been temporarily stabilized.
“But they need to be fixed,” Chidester said. The U.S. Army Corps of Engineers is investigating problems at 11 Southern California hospitals for infrastructure problems that need to be quickly addressed.
Staffed beds in ICUs across L.A. County are essentially filled beyond capacity, forcing critically ill patients to be treated in areas not normally designed for them, such as recovery rooms.
As of Wednesday, 1,635 coronavirus-positive patients were in intensive care countywide — seven more patients than the day before and triple the number from Thanksgiving,
according to state data released Thursday.
On Tuesday, the overall number of COVID-19 hospitalizations in L.A. County climbed to a new record: 8,098. The number dipped slightly Wednesday, to 8,074, but the numbers are quadruple those from Thanksgiving. .
Over the last few days, the net daily increase in COVID-19 hospitalizations in L.A. County has been roughly 100, down from about 220 in mid-December.
“Hospitals continue to be inundated with COVID patients,” Ghaly said. “While the numbers are plateauing somewhat, they’re doing so at a rate that is well above our point of comfort for all hospitals — particularly when we’re facing another potential surge in the next couple of weeks.”
The real picture of how the rest of January will fare will start to emerge next week, where hospitalization numbers will offer the first hint of how badly the rest of the month will go.
