Omicron, Now 2 Years Old, Is Not Done With Us Yet
The dominant variant of the coronavirus has proved to be not only staggeringly infectious, but an evolutionary marvel.

Nov. 21, 2023
By November 2021, nearly two years after the coronavirus emerged in Wuhan and spread across the world, the surprises seemed to be over. More than four billion people had been vaccinated against the virus, and five million had died. Two new variants, known as Alpha and Delta, had surged and then ebbed. As Thanksgiving approached, many Americans were planning to resume traveling for the holiday.
And then, the day after turkey, the pandemic delivered a big new surprise. Researchers in Botswana and South Africa alerted the world that a highly mutated version of the virus had emerged and was spreading fast. Omicron, as the World Health Organization called the variant, swiftly overtook other forms of the virus. It remains dominant now, on its second anniversary.
In the two years since its emergence, Omicron has proved to be not only staggeringly infectious, but an evolutionary marvel, challenging many assumptions virologists had before the pandemic. It has given rise to an impressive number of descendants, which have become far more adept at evading immunity and finding new victims.
“It was almost like there was another pandemic,” said Adam Lauring, a virologist at the University of Michigan.
Dr. Lauring and other Omicron watchers are now trying to make sense of the past two years in order to prepare for the future. It’s possible that Omicron will become a permanent part of life, steadily mutating like seasonal influenza. But researchers warn that the virus still has the capacity to surprise us, especially if we stop paying close attention.
When Omicron first came to light, the United States and other countries wrongly believed they could stop its spread by banning travel from South Africa. In reality, it had already spread far and wide. In a matter of days, Britain, Italy and Germany discovered Omicron in positive Covid tests.

Omicron: In the two years since its emergence, the dominant variant of the coronavirus has proved to be not only staggeringly infectious, but an evolutionary marvel, challenging many assumptions virologists had before the pandemic.
Long Covid: As more young Americans report serious cognitive problems, scientists suggest that the increase captures the effects of long Covid, most likely in addition to other effects of the pandemic, including psychological distress.
Stroke Risk: The Covid vaccines made by Pfizer-BioNTech and Moderna may be linked to a slight increase in the risk of stroke when administered along with a high-dose flu vaccine that is usually given to older people, according to a new analysis by the F.D.A.

Omicron’s gift for spreading fast was the result of dozens of mutations. They altered the virus’s surface, so that antibodies produced by vaccines or previous infections could not stick tightly to it and prevent the virus from invading cells.
“It was the first virus to figure out in a major way how to escape immunity,” said Dr. Jacob Lemieux, an infectious disease specialist at Massachusetts General Hospital.
Dr. Lemieux and many other Omicron experts suspect that the variant gained its new mutations while infecting a single person with a weak immune system. Immunocompromised people can only fight off some of the coronaviruses in their bodies during an infection, allowing the ones that remain to acquire mutations that can thwart the immune system.
“It becomes like a laboratory for virus evolution,” said Peter Markov, a virologist at the London School of Hygiene and Tropical Medicine.
As epidemiologists tracked the Omicron wave in late 2021, they saw a crucial difference from earlier surges. Compared with previous variants, Omicron put a smaller fraction of infected people in the hospital. One reason for that shift was that so many people had immunity to earlier forms of the coronavirus. Our immune defenses include not just antibodies, but special immune cells that can recognize and kill infected cells. This second line of defense held up even against Omicron, preventing many of the new infections from becoming severe.
Still, Omicron caused so many new infections — the initial wave infected almost half of all Americans, according to one recent estimate — that it still unleashed a devastating wave of hospitalizations.
The Omicron surge hit the United States and most other countries in early 2022. China managed to hold back the waves with its “zero Covid” policy, but protests against its brutality grew so intense that President Xi Jinping dropped it abruptly in November 2022. The floodgates opened: Within a few weeks, more than a billion Chinese people contracted Omicron, resulting in over a million deaths.

As Omicron moved from person to person, its descendants gained more mutations. Sometimes two Omicron viruses would wind up in the same cell, which would produce new hybrid viruses with a mix of their genes. One of these so-called recombinations hit the jackpot by mixing together two sets of evasive mutations. The result was a new hybrid called XBB.
XBB easily infected people, even those who had already been infected with Alpha, Delta or earlier forms of Omicron. As a result, XBB became dominant in the United States in early 2023.
Vaccine makers tried to keep up with Omicron’s rapid evolution. In August 2022, the Food and Drug Administration authorized booster shots that targeted the BA.5 Omicron variant, which was then dominant. In September 2023, the agency authorized an XBB shot. But XBB is now ebbing as a menagerie of even more evasive variants has evolved.
“Right now we’re in a period of chaos,” said Marc Johnson, a virologist at the University of Missouri.
Several Omicron experts said the chaos might soon end. In August, a variant called BA.2.86 emerged with a host of new mutations — likely the result, once again, of evolution taking place in an immunocompromised person.
At first, BA.2.86 did not seem to live up to its genetic potential, failing to spread fast. “If genetics was all that mattered, it would have gotten its own Greek letter,” said Thomas Peacock, a virologist at the Pirbright Institute in Woking, England. “But BA.2.86 was a bit of a damp squib.”
Over the past few months, however, the BA.2.86 lineage seems to have kicked into high gear, gaining a mutation that allows it to evade even more antibodies. JN.1, as this mutated form is known, has become the most resistant version of the coronavirus. It appears to be growing quickly in France, and may soon spread to other countries.

It is hard to predict the future path of a new variant like JN.1. Its success will depend on what kind of immune defenses it encounters while spreading from host to host. At the outset of the pandemic, things were simpler because no one had developed immunity to the coronavirus.
“At the beginning, we were one big kindergarten,” said Michael Lässig, an evolutionary biologist at the University of Cologne.
Today, in contrast, most people on Earth have immunity of one form or another, whether from a natural infection, vaccination or both. “The virus sees a much more complex ecosystem,” Dr. Lässig said.
This worldwide immunity means that a smaller fraction of people will die than did at the start of the pandemic. Still, Omicron’s toll remains heavy. The U.S. Centers for Disease Control and Prevention found that between October 2022 and September 2023, more than 80,000 people died of Covid, more than eight times as many as those who died of influenza.
As Omicron continues to evolve, epidemiologists still see a benefit to vaccinations. Justin Lessler, a researcher at the University of North Carolina, and his colleagues recently ran a projection of future Covid infections and concluded that annual vaccination campaigns could save up to 49,000 lives a year.
Those vaccines will be more effective if they’re updated to keep up with the evolving virus. But Katrina Lythgoe, a biologist at Oxford University, worries that their development will slow down as governments stop paying for genetic sequencing of new variants.
“If we don’t sequence things, then we won’t see them,” she said.

...barely anyone on BART wears masks anymore. NOT TO MENTION the fact that the sign on applies to (and was taken in) one of the newer BART trains... which are still the minority of the BART fleet.
So... yeah... not impressed.
Brasília - 26/11/2020 - Ato pacífico marca o sétimo dia da morte de João Alberto Silveira Freitas, morto por seguranças de uma unidade do Carrefour em Porto Alegre (RS). Para expressar o luto e o combate ao racismo, os manifestantes realizaram uma vigília, com vários cartazes e velas, em frente a um supermercado da rede na 402 Sul.

The bus to the BART station had an unmasked driver who laughed at me and called me "Darth Vader" (that's an insult?). That fucker coughed the entire bus ride. Fortunately, the windows were open and circulation was good on the Aranet.
I wasn't paying attention to the scale and it looks like I've made the chin a mite too big. New one is currently in progress in the correct scale.

We have two students working on this project: Dani (Margaret) Schon and Josie McCarty. They are working Monday, Wednesday, and Friday each week. They do work individually - one in the morning and one in the afternoon - so they are completely social distanced and safe. They are wearing masks and disinfect their work area before leaving and the next student arrives. There are 2 pieces that are being 3D printed for the face shields - a top piece and then bottom pieces. These files take about 3 hours to print, we are hoping to be able to print 12 - 15 face shield pieces per day, depending on the printers continuing to work properly! Just this morning, one of the printers is causing some trouble by not turning on, so Dani is troubleshooting this problem! After the pieces are printed, the students disinfect the pieces and place them in a bag, to then deliver to the CCL group in the Communications Building. They then add the plastic face shield piece and the elastic band and handle the distribution.

This full-coverage faceshield was done in 1993. The optional lower chin guard was molded in the same tool as the top part - a different B side insert was used to shut off the outer ends where the hardware attaches.
The headband has fairly long cantilevered arms extending to the attachment points for the shield. We borrowed finite element analysis services from the University of Kentucky to calculate the structure of the arms, but that didn’t work out, I think due to an input error, so I ended up recalculating them by hand.
