Covid, Omicron cases appear to peak in US


Published : 23 Jan 2022 10:19 PM

New coronavirus cases have started to fall nationally, signalling that the Omicron-fuelled spike that has infected tens of millions of Americans, packed hospitals and shattered records has finally begun to relent.

More and more states have passed a peak in new cases in recent days, as glimmers of progress have spread from a handful of eastern cities to much of the country.

Through Friday Jan 21, the country was averaging about 720,000 new cases a day, down from about 807,000 last week. New coronavirus hospital admissions have levelled off.

Even as hopeful data points emerge, the threat has by no means passed.

The United States continues to identify far more infections a day than in any prior surge, and some states in the West, South and Great Plains are still seeing sharp increases.

Many hospitals are full. And deaths continue to mount, with more than 2,100 announced most days.

But after a month of extraordinary rates of case growth, block-long lines at testing centres and military deployments to bolster understaffed intensive care units, the declining new case tallies offered a sense of relief to virus-weary Americans, especially in the Northeast and parts of the Upper Midwest, where the trends were most encouraging.

After another round of masking up or hunkering down, some were considering what life might look like if conditions continued to improve.

"Especially after this wave, the level of exhaustion in New York City cannot be exaggerated, and the level of numbness is quite significant," said Mr Mark D. Levine, Manhattan's borough president.

He added: "What we have to do now is not pretend like Covid-19 has disappeared but manage it to the point where it does not disrupt our life."

In states where new cases have started to fall, the declines have so far been swift and steep, largely mirroring the rapid ascents that began in late December.

Those patterns have resembled the ones seen in South Africa, the country whose scientists warned the world about Omicron, and the first place to document a major surge of the variant.

New cases in South Africa have fallen 85 per cent from their mid-December peak, to about 3,500 cases a day from a high of 23,400, although they remain above the levels seen in the weeks before Omicron took hold.

Scientists said it remained an open question whether Omicron marked the transition of the coronavirus from a pandemic to a less-threatening endemic virus, or whether future surges or variants would introduce a new round of tumult.

"It's important for people to not be like, 'Oh, it's over'," said public health researcher Aubree Gordon at the University of Michigan.

"It's not over until we get back down to a lull. We're not there yet."

In New York, cases are falling sharply even as deaths continue to increase, with more fatalities being announced each day than at any point since the first months of the pandemic.

Around Cleveland and in Washington, fewer than half as many new infections are being announced each day as in early January. And in Illinois and Maryland, hospitalisations and cases have started to decline.

"We are very encouraged by our substantially improving situation," Governor Larry Hogan of Maryland said Thursday, "but the next 10 days to two weeks are really going to be critical".

More states in more regions continue to show signs of improvement, with Colorado, Florida, Louisiana, Massachusetts and Pennsylvania among those now reporting several days of sustained case declines.

But the progress is not yet universal.

Reports of new infections continue to grow in North Dakota, which is averaging four times as many cases a day than at the start of January, and in Alabama, where hospitalisations have roughly doubled over the past two weeks.

Utah is averaging about 11 times as many cases a day as it was a month ago, and hospitalizations have reached record levels.

"As we've seen with Delta and previous surges, it comes in these peaks and waves, where one part of the US gets hit and another part gets hit afterwards," said infectious disease public health researcher Syra Madad in New York City.

"We are going to see that with Omicron. Even with a decline, it comes with a very long tail."

In Kansas, where daily case rates have increased 50 per cent in the past two weeks, Governor Laura Kelly announced Friday that Veterans Affairs hospitals would be accepting patients not usually eligible for care there because other facilities were strained.

"We are at an inflection point with the Omicron variant, and the strain on our hospitals is taking a toll on our health care workers and patients - all while the virus continues to spread rapidly through our communities," Ms Kelly said in a statement.

Still, there is "renewed hope" that the end of the coronavirus pandemic might be in sight, Dr Bruce Vanderhoff, director of the Ohio Department of Health, said at a news conference Thursday.

But through nearly two years of the pandemic, the country has celebrated hopeful moments before, only to be disappointed by another wave: When the first surge in cases receded, when vaccines were authorised, when a "hot vax summer" seemed to be on the horizon.

"We need to be super vigilant about what is going on internationally," said health commissioner Judith Persichilli in New Jersey, where case rates are falling quickly and where temporary morgues erected at the beginning of Omicron's onslaught never had to be used.

"Whatever is happening overseas eventually lands on our shores, and it lands first in New York and New Jersey." There has been no return to the stay-at-home orders imposed early in the pandemic, although new restrictions have emerged in some places.

Some schools and colleges have transitioned to online instruction, either as a precaution or because of major outbreaks. School closures because of the virus peaked in early January, with millions of children affected by district shutdowns and classroom quarantines. Since then, disruptions have decreased, according to Burbio, a data-tracking company.
