Los contagios de la viruela del mono han ido creciendo...Leer más
Scientists are seeing signals that COVID-19’s alarming omicron wave may have peaked in Britain and is about to do the same in the U.S., at which point cases may start dropping off dramatically.
The reason: The variant has proved so wildly contagious that it may already be running out of people to infect, just a month and a half after it was first detected in South Africa.
“It’s going to come down as fast as it went up,” said Ali Mokdad, a professor of health metrics sciences at the University of Washington in Seattle.
At the same time, experts warn that much is still uncertain about how the next phase of the pandemic might unfold. The plateauing or ebbing in the two countries is not happening everywhere at the same time or at the same pace. And weeks or months of misery still lie ahead for patients and overwhelmed hospitals even if the drop-off comes to pass.
“There are still a lot of people who will get infected as we descend the slope on the backside,” said Lauren Ancel Meyers, director of the University of Texas COVID-19 Modeling Consortium, which predicts that reported cases will peak within the week.
On Tuesday, Janet Woodcock, the acting head of the Food and Drug Administration, told Congress that the highly transmissible strain will infect “most people” and that the focus should turn to ensuring critical services can continue uninterrupted.
“I think it’s hard to process what’s actually happening right now, which is: Most people are going to get COVID, all right?,” she said. “What we need to do is make sure the hospitals can still function — transportation, other essential services are not disrupted while this happens.”
The University of Washington’s own highly influential model projects that the number of daily reported cases in the U.S. will crest at 1.2 million by Jan. 19 and will then fall sharply “simply because everybody who could be infected will be infected,” according to Mokdad.
In fact, he said, by the university’s complex calculations, the true number of new daily infections in the U.S. — an estimate that includes people who were never tested — has already peaked, hitting 6 million on Jan. 6.
In Britain, meanwhile, new COVID-19 cases dropped to about 140,000 a day in the last week, after skyrocketing to more than 200,000 a day earlier this month, according to government data.
Numbers from the U.K.’s National Health Service this week show coronavirus hospital admissions for adults have begun to fall, with infections dropping in all age groups.
