This analysis in The Times looks at the latest information on the omicron variant gathered in the UK and what it means for the capital London and the UK. It looks at the hospital admissions in January 2021 that could be expected in the UK compared to  January 2020. A big spike infections with a sharp fall is the scenario seen as expected based on experience in South Africa, with 2% of cases as hospital admissions as in the prior January, or in a "milder" scenario somewhat smaller percentage.

Omicron cases are up in an almost vertical line on a graph with cases doubling every 2-3 days in the UK, similar to the pattern in South Africa during the beginning of the spread in South Africa. Since then early data in South Africa show the trend in the province of Gauteng, center of the omicron outbreak in South Africa in the Johannesburg area, has reached its peak. On Dec. 16 it recorded 27% of national infections compared to 70% the week before. Head of the National Institute of Communicable Diseases in South Africa, Michael Groome, says "we had areally dramatic increase in Gauteng, which has now leveled off."  Hospital admissions in South Africa show a different pattern than earlier hospital admission rates in previous waves, with only 1.7% of cases being hospitalized in this Omicron wave compared to 19% for the Delta variant wave at a similar point in the wave, says Health Minister Joe Phaahla. In UK as of Dec. 14, this WSJ report cites health authorites saying 73% of cases in London are omicron variant, doubling every 1-2 days, with omicron making up 41% of all cases in England. In the US the Centers for Disease Control show Omicron variant making up 2.9% of all cases in US as of Dec. 11, with highest concentration in New York, New Jersey of 13.1%. Proportion of positive tests went up from 3.3% to 5% in New York City. A convention in New York City, Anime convention at Javits Center, November 23, 2021, shown in a recent NYT report, could potentially have acted as a super spreader event in New York according to NYT though not confirmed, similar to football stadiums events in Italy in March 2020. Dense atmosphere and large crowds increase the risk of a super spreader event happening, say experts. ...

German Heath Minister Karl Lauterbach says vaccine mandates are the only way out of this pandemic. Speaking to German daily Welt he said, gaining immunity through infection was a "dirty vaccination" that made little sense as it would not protect one against a more harmful variant. He saiid that it "would be naive to think that omicron is the end of the pandemic." Omicron would not make one immune to the next viral variant. "No one can guarantee that a variant will not develop soon that is much more dangerous."

Lauterbach says 25 million doses of the Moderna vaccine have been procured that would be enough for 50 million booster shots to be done in the first quarter of 2022.

In 2020 soccer at filled football stadiums in northern Italy acted as superspreader events. Here the NYT looks at conventions as superspreader events and one recent convention in New York City, Anime (Japanese animation) convention at Javits Center, in late November 2021, that potentially could have acted as a spreader event though not confirmed according to NYT. Dense atmosphere and large crowds increase the risk of a super spreader event happening say experts.This happens as the new omicron variant in South Africa is seen in several countries.

South Africa feels a sense of relief as omicron cases follow a pattern of very steep upward increase, followed by a short period of a month, and then a very steep decrease. Cases in South Africa with a population of 60 million, about the size of Britain, dropped from 27,000 at the peak to about 15,000 on December 21, 2021. The area around Johannesburg was hardest hit. The median age is 27 years in South Africa, 40 in UK and 43 in Italy. With younger populations in India and parts of Asia South African population demographic is closer to India than it is to Europe where populations are much older. Scientists do not want to extrapolate from the South African experience with Omicron for this reason. Immunity from vaccination and prior infection could be contributory causes to the less severity of omicron say NCID scientists. "In South Africa this is the epidemiology. Omicron is behaving in a way that is less severe," says Dr. Cheryl Cohen, of the National Institute for Communicable Diseases (NCID). "Compellingly together our data really suggest a positive story of a reduced severity of omicron compared to other variants," he said at a conference with other scientists on Wednesday, Dec. 22.  ...

The market for oil field equipment is tight with 90% utilization, making it harder for larger oil producers to drill more oil wells for shale oil in the US. Large US shale oil producers reduced production when oil prices plunged and did not come back leaving smaller oil producers to increase production as prices went back up in 2021. Oil prices are now expected to reach $100 per barrel for the first time since 2014.  Saudis and Russia are not expected to increase production say experts. The possible Russian invasion of Ukraine and shortage of energy supplies is also a factor. Oil demand in the US and Europe has rebounded with milder covid-19 from Omicron variant and fewer lockdowns. Automobile use is also up in the US with November showing 12% increase in miles driven over the prior year, according to the Federal Highway Administration. Low inventories and resilient demand, and low spare capacity will keep prices surging to $100 from today's price of Brent crude oil at $89 in January 2022.   ...

In a factory the size of 5 football fields located in Gurnee, Illinois, Abbott Labs makes its BinaxNow Covid-19 home tests. Abbott turned out 1 billion tests in 2021 and at one point had 80% of the market. Along with Pfizer vaccine, BinaxNow Home covid-19 tests are a dominant product during the pandemic. Abbott generated a fifth of its $43 billion in revenue from these home tests. Abbott faced several hurdles along the way. It gained when the US government authorized it to make the test. Yet after vaccination took off by mid 2021 the demand for tests declined and Abbott nearly idled its giant factory in Gurnee. Delta and Omicron variants led to a sudden reversal and surge in demand. Abbott developed its test based on an existing design it used in the US for flu tests, by a company it inherited by acquisition called Binax. To do that test one sends a swab up the nose, add that sample and a liquid mixture to a rectangular paper card, and close the card shut. The liquid then travels up the paper strip, revealing one or two pink lines, one for negative, two for positive. This is done in 15 minutes and the simple design described as a lollipop shape, put Abbott far ahead of competitors. The US FDA authorized Becton Dickinson and Quidel to make the tests before it authorized Abbott, but these rival companies had a poor and complex design. The Trump administration gave Abbott a $760 million contract to buy 150 million tests for distribution to health departments, long termcare facilities, nursing homes, and schools. And by October 2020 Abbott was already making 50 million tests a month. When it comes to distribution Abbott tapped into its pharmacy connections for baby products such as Similac baby formula. This gave it an advantage over Quidel and others who also lacked the manufacturing knowhow for large scale ramp up. The BinaxNow in pharmacies was sold at $24 for a box of two tests, while government paid $5 for one test. Abbott says it makes $ 7 per single consumer test. Yet there was one problem waiting to hit Abbott in 2021- demand dried up as the vaccination campaign took off. In fact the plant manager, Mr. Rodriguez, planned to move to another job inside Abbott as production declined. Then came the Delta variant and he was asked to ramp up production again. With Omicron demand soared. The Biden administration committed $3 billion to help boost test production and asked Kroger and Walmart to sell over the counter tests at cost for 3 months. Abbott had to lure workers from Amazon at $25 an hour for the Gurnee plant expansion. What was learned by the government and Abbott from this experience? The US government now looks for ideas in meeting demand volatility, supply challenges and production needs,. Sustaining production capacity is important for future virus flareups- a new government-industry partnership is required for maintaining test making infrastructure. With government help Abbott plans now to keep the facility at Gurnee operating indefinitely. ...

Latin America has made a huge turnaround through successful vaccination drives. Today more people are vaccinated as a percentage of the population in Latin America at 62% than in the US at 56% or Europe at 60%, according to Our World in Data project at Oxford University. There is little resistance to vaccines in Latin America after successful vaccine campaigns against yellow fever and other diseases. During the first year of the pandemic Latin America had one third of the deaths in the world with 8% of the population. Deaths after vaccination drives have dropped to 8%.  Brazil with 617,000 deaths from coronavirus was second only to the US with 800,000 deaths. Brazil is now back to normal after a successful vaccination drive that has 66% of the population fully vaccinated, and 80% with one dose, some of the highest rates in the world, according to Our World in Data at Oxford University. In Colombia with 50 million population about 50% of people are fully vaccinated. Cases have dropped from 30,000 in June to 2000 a day and deaths from 700 daily that month to 50 a day in December 2021. In Buenos Aires, Argentina's capital, 83% of three million population are fully vaccinated, 14% have received a booster. Buenos Aires city health minister says Argentine society has an affinity for vaccination campaigns. "They rapidly accepted receiving them," he says. Yet from the point of view of new variants emerging there is a different situation in rural areas. In industrial states such as Sao Paulo 78% are fully vaccinated, yet less than 40% are fully vaccinated in poor Amazon state of Roraima.   We make it a point to honor the brave reporters in these countries who provide the reports in the WSJ, as we did earlier for NYT Stephanie Nolan's reports from South Africa and Zambia about frontline workers against Omicron in Africa.  Luciana Magalhaes in Sao Paulo, Jenny Carolina Gonzalez in Bogota, and Sylvina Frydlewsky in Buenos Aires and Kejal Vyas writing this report from San Salvador. ...
