Omicron

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

Why is the government so scared of the Omicron variant? So far, most of the evidence we have for transmissibility and virulence of Omicron is based on very limited data from South Africa, but the UK Health Security Agency (UKHSA) has now published its own preliminary study of the variant — the results of which will presumably have been available to ministers and scientific advisers prior to Wednesday’s decision to enact ‘Plan B’. They appear to show a variant which is more transmissible, more likely to evade vaccines and more likely to reinfect people who have previously had Covid. But there is a very big caveat: they are based on

There was nothing but gloom about the Omicron variant at yesterday’s No. 10 press conference. But with reporters preoccupied with last year’s Christmas parties, no one thought to bring up a statement by Tedros Adhanom Ghebreyesus, the head of the WHO, who earlier told reporters that there is ‘some evidence that Omicron causes milder disease than Delta, but again it’s still too early to be definitive.’  You don’t want to make decisions before you have good evidence, but if it does turn out that Omicron is a milder disease, won’t the government’s efforts to suppress it with travel bans and restrictions be counter-productive? If Omicron makes people significantly less ill than Delta, it should be

It will be weeks before we know just how worried we should be about Omicron — but the first indications seem hopeful. The epicentre of the first recorded outbreak has been the subject of a study that suggests that it may be milder than Delta. Early data from 166 patients in the Tshwane district comes with the usual caveats, especially that very little Omicron has been found among South African over-65s. But the study nonetheless has two weeks of hospitalised Omicron patients to analyse — more than any other country. Here are the main indications so far:  Fewer people hospitalised with Omicron have ended up in intensive care: 8 per cent, compared to 25 per

There are good reasons to be concerned about the Omicron variant. For starters, this strain has 50 mutations, twice as many as Delta. Early reports from South Africa, where the virus has been circulating for a while, suggest it’s outcompeting Delta and spreading rapidly. There is a concern, too, that it could blunt the vaccines, because more than half of the new mutations affect the spike protein that the jabs are designed against. But all of this is theoretical: we need real-world data. So we won’t know whether it really is more transmissible, or how the vaccines perform against it, until long after Christmas. The concern, for now, remains Delta, as

Boris Johnson is relying heavily on the booster programme to protect Britain from any additional threat posed by the Omicron variant. The Prime Minister made that very clear at this afternoon’s Covid press conference in Downing Street, opening by saying that ‘there is one thing we already know for sure: right now, our single best defence against Omicron is to get vaccinated and get boosted’. Temporary vaccination centres were going to pop up ‘like Christmas trees’, he said. He also seemed committed, if not to boosterism in the form of unbridled optimism about how the next few months would go, then at least to a reluctance to tell people to change
