How China’s COVID Crisis Could Spawn the Next Omicron-Level Disaster

China’s COVID disaster is entering an important phase. Subvariant BA.5.2 of the SARS-CoV-2 virus is essentially spreading unchecked through a population of 1.4 billion with weak immunity to COVID. And as the virus spreads, it is also mutating—Fast.

If the rest of the world experiencing the same form of COVID is any indication, one of two things will happen in China in the coming weeks and months. The virus is stable at the genetic level and produces a series of sub-variants closely related to BA.5.2—variants to which the gradually expanding immunity of the Chinese population has can be handled. Or, uncontrolled transmission and runaway mutations will lead to Gene breakthrough for SARS-CoV-2.

In that case, we might see the first new major variant since omicron appeared over a year ago.

That’s the worst case scenario. “The worry is that new variants, or sub-variants of Omicron, will be created that are more resistant to immunity and could infect people outside of China,” said John Swartzberg, professor. countries, who are currently protected by some vaccine or previous infection.” Honors in Infectious Diseases and Vaccines at the University of California-Berkeley School of Public Health, told The Daily Beast.

For all the debates about shutdowns, masks and vaccines, most countries make the mistake of adopting a fairly effective approach to COVID. Between 2020 and 2021, many governments have restricted—if not closed—retail businesses, schools, crowds, and travel. That has helped slow the spread of the virus until a vaccine begins in late 2020.

Over the next two years, most of the world’s eight billion people have received at least one reasonably effective dose of a COVID vaccine—and billions will also be fully vaccinated and boosted. That helps countries safely gradually lift restrictions. Most of the world has reopened.

Yes, that means more viruses spreading at first. And by the end of 2021, it created the Omicron variant and its many sub-variants, which are still dominant to this day. In most countries, vaccines have reduced the worst impact of consecutive Omicron waves. Case rates increased and decreased, but overall, the number of hospitalizations and deaths tended to decrease.

Most of the world has entered a beneficial cycle that began with mass vaccination. The protection from the vaccine gradually wears off, but the natural antibodies from the previous infection more than make up for it. People get infected and re-infected, but each infection renews natural antibodies normally make the next infection milder than the last.

Epidemiologists think this cycle will continue unless—and until—the SARS-CoV-2 virus makes some sort of evolutionary leap that renders all existing antibodies ineffective. “The more infections happen, for example in China, the more times the Omicron evolved dice roll and the more chances there are. [there are] Eric Bortz, a virologist and public health expert at the University of Alaska-Anchorage, told The Daily Beast. “It’s like adding new seasoning to the soup.”

If that evolutionary leap happens, it will likely happen in China, the only country that went into lockdown in early 2020. and stayed lock for almost three years. It was only on December 8, after widespread public protests in many major cities, that the Chinese Communist Party final remove major restrictions.

“The situation completely changed on December 8,” Ben Cowling, a professor of epidemiology at the University of Hong Kong, told The Daily Beast. The restrictions have contained COVID, resulting in one of the lowest overall case rates of any country. But lack of infection also means lack of natural antibodies.

Yes, about 90 percent of China’s population has been at least partially vaccinated. But most of the Chinese were stabbed more than a year ago. By December, the protection from those early vaccinations had dwindled considerably.

China may even have its own recombinant version of XBB.

So when restrictions were lifted and the 1.4 billion Chinese people finally started going out and traveling, they did so without the natural immunity that the rest of the world has. the world has struggled to obtain through past infection. It’s no surprise that SARS-CoV-2 spreads Fast in China starting six weeks ago. Cindy Prins, an epidemiologist at the University of Florida, told The Daily Beast: “It is inevitable that the end of the blockade will lead to a large number of infections.

No one outside the Chinese Communist Party knows exactly how many Chinese people have contracted COVID in recent weeks. The paranoid, authoritarian CCP stopped sharing good data shortly after lifting restrictions. But testing for air travelers from China is fragmentary evidence of a major crisis.

The same test, along with hundreds of virus samples that Chinese epidemiologists uploaded into the global COVID database called GITHub, which tells us what form of the virus is dominant in China. While most of the world is on the verge of a mid-sized winter wave caused by XBB, a “recombinant” mix of several Omicron sub-variants, China is now catching up to BA.5.2 , a sub-variant that prevailed everywhere else about six months ago.

And those millions—or even dozens out of millions—China’s BA.5.2 infections created the trio of BA.5.2 byproducts. Virus samples from several Chinese cities, uploaded to GITHub last week, are the first evidence of BA.5.2.48, BA.5.2.49 and BA.5.2.50. That’s right: China is now developing its own unique forms of COVID.

That, of course, is a problem for China, which has weeks or months ahead as authorities scramble to organize new rounds of vaccinations. The injections are categorization — a desperate attempt to prevent overcrowded hospitals from collapsing as China’s population slowly and painfully builds up natural immunity.

With China’s extremely high COVID infection rate, a spike is inevitable. The most optimistic scenario would be for the virus’ evolution to approach BA.5.2—albeit at a heavy cost to millions of Chinese every day. The domestically produced Chinese vaccine seems to work well with Omicron and its sub-variants. Natural antibodies from BA.5.2 infection will provide strong protection against BA.5.2.48, 49, 50—and even 51, 52, 53, etc.

Sub-variables can be mixed, as they do in much of the rest of the world. “China may even have its own version of recombinant XBB,” Edwin Michael, an epidemiologist at the Center for Global Health Infectious Disease Research at the University of South Florida, told The Daily Beast. That sub-variant is more contagious than the previous sub-variants, and it somewhat evades our antibodies. But it’s still a form of Omicron. that is manageable.

But a large outbreak in a population of 1.4 billion increases the likelihood that the virus will make an evolutionary leap. Similar to the leap that gave rise to the Delta variant at the end of 2020 and the Omicron a year later. A new variant may be even more contagious than Omicron’s sub-variants—and it can total evade our antibodies.

A new variant could spread from China to the rest of the world, increasing in populations that have become complacent with COVID because they have only been dealing with Omicron and its sub-variants for more than a year now on.

Remember early 2020, when we had no effective vaccines nor natural antibodies and there was no way to slow down the transmission of the virus except by wearing a mask and staying at home? That’s the worst case scenario, for the world as a whole, if China’s growing BA.5.2 outbreak reaches a gene drain rate, so to speak, and develops an entirely new variant.

Prins emphasizes that a dangerous new variant is unlikely. The US weathered the worst wave of Omicrons without producing a new variant. So are Europe and Asia outside of China. “It is possible that after this first wave of post-Zero-COVID subsides and immunity to it wanes, we may see new variants arise,” Prins said, “but I don’t think that has any bearing on the disease. more likely to happen in China than [it was] in other countries.”

But it can. And that’s a little bit than every day passed until China’s contagion wave peaked. Alert. Be promoted. The pandemic is not over.
