Does Warwick’s Omicron modelling make restrictions more likely?

Two weeks ago, the London School of Hygiene and Tropical Medicine (LSHTM) and Imperial College both published modelling showing frightening scenarios if the government did not react to the Omicron variant by imposing immediate restrictions on our day to day lives. The former suggested that hospitalisations could peak at 7,190 a day in January in its most pessimistic scenario; the latter was reported as suggesting that deaths might peak at 5,000 a day in January. Both figures, however, were made on the assumption that Omicron was every bit as virulent as the Delta variant. Since then, several UK studies have suggested that this is not the case, with data showing

Covid is surging. So why is intensive care bed usage falling?

Omicron is sending Covid case numbers surging ( a new high of 189,000 cases reported yesterday) and hospital admissions along with it. But another important piece of data, intensive care admissions, shows a significant fall. This is early data, but worth noting as it may be part of an important trend. And it adds context to comments by Chris Hopson, Chief executive of NHS Providers, that the system may be better prepared than case numbers suggest. First let’s look at London; the Omicron epicentre. Hospital figures are rising fast – in part due to patients who are being primarily treated for something else (blue, below – that is now true

Working out length of hospital stay for Covid patients: a technical note

Length of hospital stay is a crucial metric, but hard to do with much accuracy unless each patient is certified Omicron or Delta. The closest proxy we have right now is information on patient stay and there are graphs for two cohorts: those admitted from 1 May (third wave) and from 1 December. The graphs were published in the CO-CIN study dated 22nd Dec (Fig 8). The younger age groups are at the top. Those who were discharged on the left, those who died on the right. The line drawn on each chart shows 14 days on, and indicates what percent of patients were discharged or had died by that point.

Will Trump’s pro-vaccine stance prove his undoing?

Donald Trump famously boasted that he could ‘stand in the middle of Fifth Avenue and shoot somebody’ and still not lose voters. That was back in 2016 and the following years proved his point. We are now in the winter of 2021, however, and the 45th president may at last have stumbled across a way to alienate his fan base — by endorsing vaccines. Covid is today the most hostile frontline in America’s all-consuming culture war. Resistance to the national vaccination drive has become the stickiest point. You are either pro-freedom or in bed with the Great Globo Pharma Conspiracy. Trump has adopted a more middle-ground position: encouraging people to take the vaccines while

Remember panic-buying? Here’s what will happen next time

It’s post-Christmas, and there are already murmurs about supermarkets with empty shelves. Just as with the petrol shortage in September and shortages of loo paper at the beginning of the first lockdown, these things can rapidly develop into major crises, purely as a result of panic-buying. Tesco, whose store on the Isle of Wight is reportedly especially empty post-Christmas, denies it has any problem with its supply chain — which had been threatened with disruption thanks to an industrial dispute involving the company’s lorry drivers in early December. People may, on the other hand, have stocked up more than usual in response to fears of a post-Christmas lockdown — a fear which

The churches must stay open

Hooray for Cardinal Vincent Nichols, who used the one day of the year when his pronouncements are amplified by the season to ‘sincerely appeal that [the government] do not again consider closing churches and places of worship.’ He said in a BBC interview he believed it had been demonstrated that the airiness of churches meant they are ‘not places where we spread the virus’. Mind you, Catholic churches weren’t as bad as the Church of England This is, of course, entirely sensible. It was nuts for churches to close at the start of lockdown, at least as spaces for prayer if not for communal worship. Pretty well any church is ‘Covid-safe’, in

The misery of Macron’s Covid clampdown

My daughter’s Christmas won’t quite be the same this year. She and I are in England but her French mother has been prevented from making the trip by her president. It’s a funny world when hundreds of people can quite easily cross illegally from France to England in small boats – 1,200 in four days last week – but a mother isn’t allowed to take a train to be with her daughter at Christmas. But that is France for you in what Macron’s opponents call his ‘Covid Dictatorship’. Even so his authoritarian measures are doing him and his country a fat lot of good. Yesterday France recorded 91,000 new cases

Will Omicron overwhelm the NHS? The crucial missing data

If you catch Omicron your risk of ending up in hospital is between 50 to 70 per cent less likely than if you’d had Delta. That’s according to a new analysis released this evening by the UK Health Security Agency. It’s another blow to the case for lockdown. That case for lockdown goes like this: Omicron is growing exponentially and its casualties will overwhelm the NHS unless action is taken to slow the growth. The cautious course of action is to wait until we know more about crucial unanswered questions, such as: What is the limit to Omicron’s growth? How much milder than Delta is it? Is Imperial’s figure of

Sage modellers start to accept that Omicron is milder

Public health officials in Britain and South Africa were on different planets for about a fortnight. While those in South Africa kept presenting data suggesting that Omicron caused less severe disease than earlier variants, scientists in Britain continued to claim it was too early to say. Scenarios published by the London School of Hygiene and Tropical Medicine (LSHTM) last week pictured a frightening picture of January, suggesting that hospitalisations could peak above previous waves. An assumption was made that Omicron was just as likely to land you in hospital or kill you compared with Delta. As LSHTM admitted, quite a big assumption:- Due to a lack of data, we assume Omicron has the

Sage memo makes the case for lockdown

On Monday, Covid restrictions were rejected after the cabinet debated the issue robustly for the first time since the pandemic started. The Prime Minister said he’d revisit the decision, so the debate is very much still ongoing. But it wasn’t just ministers meeting that day. Sage assembled its experts as well, with over 70 scientists and government officials in attendance. The minutes, seen by The Spectator, give an interesting summary of the official case for more lockdown restrictions. Everyone is wrestling with two questions; if there are no more restrictions, how far will Omicron case numbers rise? And how will that translate into hospitalisations? If there is reason to believe

Should businesses receive more Covid support?

As government considers whether to lock us down once again, should it put economic support for businesses affected back on the table? The combination of Plan B and Boris Johnson’s insistence that we modify our social behaviour has led to empty cinemas, ghost trains, cancelled gigs and ‘postponed’ Christmas parties. Just as the economy was getting back on its feet, the unofficial guidance to avoid social events is knee-capping it once again, forcing the Chancellor to not only drop his December plans but to announce yet more taxpayer-funded business compensation. So far he’s fallen down on the side of more support, though nothing (yet) like last time. Businesses in England that

It’s time to end the era of forced lockdown restrictions

Monday’s Cabinet meeting held over Zoom was a fraught affair by the sounds of it. Michael Gove and Sajid Javid were reportedly the leading voices calling for more restrictions on household mixing and on the hospitality sector, while the likes of Rishi Sunak and Liz Truss argued that the data did not warrant such a draconian and retrograde step. The Prime Minister seems to have been swaying somewhere in the middle. In the end it was agreed that no new restrictions would be imposed that day but the data would be constantly analysed with a view to imposing restrictions swiftly and before Christmas if alarming trends were picked up on

Is Omicron now falling in South Africa?

Man makes Covid predictions and God laughs. Yet with the stakes this high in Britain, every bit of real-world data is useful. That’s why South Africa is so important: it’s a country with a well-digitised healthcare sector that we have to thank for sequencing the Omicron variant, and has been first to experience the impact. That’s why its figures, released daily, are being watched so eagerly world over. Right now, there are two questions: is Omicron now falling? And if so, what conclusions can we draw? The epicentre is Gauteng province: home to Johannesburg, Pretoria and about a quarter of South Africans. The below chart adjusts for population and shows that

Is Piers Corbyn really dangerous?

I thought the police statement — bureaucratic, anonymised, bone-dry – got the tone just right. In confirming the arrest of Piers Corbyn on suspicion of encouragement to commit arson, a spokesman confirmed only that ‘a man in his 70s’ had been arrested in Southwark, south London on Sunday morning. This, for those who missed it, is understood to relate to Mr Corbyn’s fire-breathing (literally: he took his nylon-clad life in his hands with a stunt involving lighter-fluid) speech to an anti-vax rally in the capital. He told his audience, presumably once he’d had a Murray Mint to get the taste of the lighter fluid out of his mouth, that we

My Twitter conversation with the chairman of the Sage Covid modelling committee

The latest Sage papers have been published, envisaging anything from 200 to 6,000 deaths a day from Omicron depending on how many more restrictions we’ll get — up to and very much including another lockdown. Earlier today I had an unexpected chance to ask questions of Graham Medley, the chair of the Sage modelling committee.  He’s a professor at London School of Hygiene & Tropical Medicine (LSHTM) which last weekend published a study on Omicron with very gloomy scenarios and making the case for more restrictions. But JP Morgan had a close look at this study and spotted something big: all the way through, LSHTM assumes that the Omicron variant is just as deadly as Delta. ‘But

Pubs and restaurants are being decimated by Covid uncertainty

The run up to Christmas is normally a merry time for the hospitality industry. Our nation’s restaurants, pubs and bars are usually bursting at the seams. Most people are out celebrating with their family, friends and colleagues – with crackers being pulled, pigs in blankets served and a glass or two of mulled wine drunk under the mistletoe. Yet, the exact opposite is happening right now for the hospitality industry in the UK. Instead it’s the nightmare before Christmas. Ever since people in Britain have been told to work from home by the government and told to cut back on socialising by chief medical officer Chris Whitty, pubs and restaurants have

Omicron is now Britain’s dominant Covid strain

If you test positive for Covid now in Britain, the odds are that it’s Omicron: it’s now the dominant strain in England and Scotland. Data released this evening by the UK Health Security Agency showed that by Tuesday, 54 per cent of PCR tests were positive for S-gene target failure (a proxy for Omicron). For perspective, it has only taken eight days for the variant to become dominant: Delta took nearly a month. North of the border, Sturgeon said that the ‘tsunami [of cases] was starting to hit’ and confirmed that in Scotland more than half of cases were Omicron too. Again, that’s using S-gene dropout as a proxy. Some

Macron’s British travel ban is entirely political

Emmanuel Macron subjected France to a two-hour primetime television interview on Wednesday evening which must have been a pre-Christmas treat for the nation. Just under four million tuned in to see Macron discussing his achievements as president in what was a polished performance; not since Tony Blair has a world leader been such a consummate actor as Macron. He declined to confirm that he will be standing for a second term in April’s presidential election but his people know that he will. There was one fly in the ointment, however, a buzz which has been distracting Macron for months: Covid. France is only just emerging from a ‘fifth wave’ of

Why Omicron may not lead to a surge in hospitalisations

There were two takeaways from last night’s press conference: firstly, the hard data showing that the number of recorded cases of Covid had surged by 19,000 – or 28 per cent – in a single day. Second was the assertion that, as a result, the NHS is in danger of being overwhelmed. What was lacking was the hard data on hospitalisations and the number of people in hospital. Although you would never have guessed from the tone of the conference, these both fell. The number of people admitted to hospital – a figure which runs a few days in arrears owing to a delay in the four constituent nations of

Boris Johnson is in a bind on Covid

This morning, it’s the Tory party versus the scientists, with a number of Conservative MPs seeing red following Wednesday’s downbeat press conference on the Omicron variant. As the number of Covid cases soars, Boris Johnson has been accused of a lockdown by stealth – after he appeared alongside Chris Whitty in a press conference urging caution over Christmas. The Chief Medical Officer suggested people ought to prioritise the social events they most care about. This morning Whitty is giving evidence to MPs where he has suggested it is too early to say whether further restrictions will be needed. In all of this, no one is quite sure where the Prime
