COVID case counts may be losing importance amid omicron

The explosive summation successful U.S. coronavirus lawsuit counts is raising alarm, but immoderate experts judge the absorption should alternatively beryllium connected COVID-19 infirmary admissions. And those aren’t climbing arsenic fast.

Dr. Anthony Fauci, for one, said Sunday connected ABC that with galore infections causing fewer oregon nary symptoms, "it is overmuch much applicable to absorption connected the hospitalizations arsenic opposed to the full fig of cases." Other experts reason that lawsuit counts inactive person value.

As the super-contagious omicron variant rages crossed the U.S., caller COVID-19 cases per time person much than tripled implicit the past 2 weeks, reaching a record-shattering mean of 480,000. Schools, hospitals and airlines are struggling arsenic infected workers spell into isolation.

Meanwhile, hospital admissions averaged 14,800 per time past week, up 63% from the week before, but inactive abbreviated of the highest of 16,500 per time a twelvemonth ago, erstwhile the immense bulk of the U.S. was unvaccinated. Deaths person been unchangeable implicit the past 2 weeks astatine an mean of astir 1,200 per day, good beneath the all-time precocious of 3,400 past January.

Public wellness experts fishy that those numbers, taken together, bespeak the vaccine’s continued effectiveness astatine preventing superior illness, adjacent against omicron, arsenic good arsenic the anticipation that the variant does not marque astir radical arsenic sick arsenic earlier versions.

Omicron accounted for 95% of caller coronavirus infections successful the U.S. past week, the Centers for Disease Control and Prevention reported Tuesday, successful different denotation of however astonishingly accelerated the variant has dispersed since it was archetypal detected successful South Africa successful precocious November.

Dr. Wafaa El-Sadr, manager of ICAP, a planetary wellness halfway astatine Columbia University, said the lawsuit number does not look to beryllium the astir important fig now.

Instead, she said, the U.S. astatine this signifier of the pandemic should beryllium “shifting our focus, particularly successful an epoch of vaccination, to truly absorption connected preventing illness, disablement and death, and truthful counting those.”

Daily lawsuit counts and their ups and downs person been 1 of the astir intimately watched barometers during the outbreak and person been a reliable aboriginal informing motion of terrible illness and decease successful erstwhile coronavirus waves.

But they person agelong been considered an imperfect measure, successful portion due to the fact that they dwell chiefly of laboratory-confirmed cases of COVID-19, not the existent fig of infections retired there, which is astir surely galore times higher.

The regular lawsuit counts are besides taxable to chaotic swings. The fig of caller cases recorded connected Monday topped an unprecedented 1 million, a fig that whitethorn bespeak cases that had been held up by reporting delays implicit the vacation weekend. The seven-day rolling mean is considered much reliable.

Now, the worth of the regular lawsuit number is being called into question arsenic ne'er before.

For 1 thing, the skyrocketing summation reflects, astatine slightest successful part, an omicron-induced stampede among galore Americans to get tested earlier vacation gatherings, and caller investigating requirements astatine workplaces and astatine restaurants, theaters and different sites.

Also, the existent fig of infections is astir apt overmuch higher than the lawsuit number due to the fact that the results of the at-home tests that Americans are rushing to usage are not added to the authoritative tally, and due to the fact that agelong waits person discouraged immoderate radical from lining up to get swabbed.

But also, lawsuit numbers look to output a little utile representation of the pandemic amid the dispersed of omicron, which is causing tons of infections but truthful acold does not look to beryllium arsenic terrible successful its effects.

Case counts person mislaid relevance, said Andrew Noymer, a nationalist wellness prof astatine the University of California, Irvine.

“Hospitalizations are wherever the rubber meets the road,” Noymer said. “It’s a much nonsubjective measure." He added: "If I had to take 1 metric, I would take the hospitalization data.”

Even infirmary numbers aren't a cleanable reflection of illness severity due to the fact that they see patients admitted for different wellness problems who hap to trial affirmative for the coronavirus.

Keeping way of COVID-19 admissions tin archer doctors thing astir the seriousness of the microorganism and besides the capableness of hospitals to woody with the crisis. That, successful turn, tin assistance wellness leaders find wherever to displacement instrumentality and different resources.

Still, wellness experts are not prepared to bash distant with lawsuit counts.

“We should not wantonness looking astatine lawsuit numbers," said Dr. Eric Topol, caput of the Scripps Research Translational Institute, "but it is important to admit we’re seeing lone a information of the existent fig of cases.”

Ali Mokdad, a prof of wellness metrics sciences astatine the University of Washington successful Seattle, said that for each caller corruption detected, the U.S. is missing 2 cases. But helium said tracking the fig of affirmative trial results is inactive important arsenic omicron makes its mode crossed the land.

Case numbers tin constituent to aboriginal blistery spots and bespeak whether a question of corruption has peaked, Mokdad said.

Also, lawsuit counts volition proceed to beryllium important to radical who are susceptible due to the fact that of property oregon wellness reasons and request a consciousness of the virus' dispersed successful their communities truthful they tin marque decisions astir precautions, helium said. Hospitals, schools and businesses request to program for absences.

“To springiness up connected knowing if cases are going up oregon down, it’s flying blind. How tin we arsenic a state not cognize the epidemic curve for infection?” Mokdad said.

If investigating has mislaid its relevance, helium said, it is due to the fact that the U.S. ne'er developed a mode to consistently and reliably show infections.

“It’s not acceptable to screen nonaccomplishment by changing the rules," helium said.
