South Africa’s Covid cases rise by 408% in a week as Omicron wave continues – but early data suggests FEWER people are being hospitalised
Covid案件 南非 have soared by a massive 408 per cent in just one week while deaths rose from eight to 21 across the same time period, 根据最新数字.
The country’s National Institute for Communicable Diseases recorded another 16,366 cases in the last 24 小时 – with the vast majority in epicentre Gauteng province.
This was a 408 per cent increase from last Saturday, when just 3,220 new infections were registered across the previous 24 小时. It is not known which variant the new cases recorded were.
The Omicron-stricken country also recorded 21 deaths on Saturday, 向上 162 per cent from last week when 8 deaths were announced.
NICD data is based on lateral flow and PCR tests done across South Africa every day. It showed that in the country’s nine provinces most new infections were recorded in Gauteng with 11,607 新案件.
The latest figures bring the total number of cases in South Africa up to 3,020,569, while the number of deaths have increased to a total of 89,956.
South Africa is seeing a meteoric rise in its cases amid the rampant spread of the Omicron variant, which scientists say has already reached every province in the country.
Commenting on the surge in Omicron cases in Tshwane, health expert Mia Malan, from Johannesburg, suggested the symptoms of the Omicron strain may be milder due to the low number of hospitalisations with the strain so far.

Sharing Omicron figures from the Steve Biko/Tshwane District Hospital Complex, 她发了推文: ‘Most COVID19 patients didn’t know they had COVID when they got admitted (they were admitted for another condition).’
Ms Malan added that 80 per cent of admissions at the Tshwane hospital complex so far have been people younger than 50, 与 28 per cent being between 20 和 29 岁.
At the Dr George Mukhari Academic Hospital in Ga-Rankuwa, 14 其 80 Covid patients were on supplemental oxygen and one was on a ventilator, 而 83 per cent were on ‘room air’, 研究发现.
Public Health officials in Gauteng — where Johannesburg is based — say their R rate has surged to 3.5 from around one a month ago. It means every ten people infected with the virus are now spreading it to 35 其他. 在英国, the R rate has never risen above 1.6.
While Omicron’s infectiousness seems unquestionable, there is growing uncertainty about how well it can evade vaccines and how severe the illness it causes will be. A pre-print published in the country found the variant was at least two-and-a-half times better at re-infecting people than all other variants.
Public health experts in South Africa and the WHO have insisted cases are only mild and vaccines should still be highly effective against the strain, despite a lack of data. But UK Health Security Agency epidemiologist Meaghan Kall warns that data currently suggests Omicron may be ‘worse’ than Delta.
Fears are mounting it is already spreading in the UK after Nicola Sturgeon warned six cases were linked to a Steps concert. Official data suggests the variant may be transmitting in England as the proportion of suspected cases rockets. UK officials have confirmed 134 Omicron cases to date.
Britain’s Covid crisis has presented a mixed picture today with deaths falling but cases and hospitalisations continuing to rise, according to Government data.
Figures from the country’s National Institute for Communicable Diseases showed infections are rocketing in Gauteng province at the epicentre of the outbreak. They are also surging in the country’s eight other provinces
The above map shows the percentage change in Covid cases across South Africa today compared to the same time last week. It shows that in eight of the nine provinces infections rocketed by more than 300 每周百分比. The sharpest rise was recorded in Eastern Cape where infections surged 1,068 百分
UK Health Security Agency (UKHSA) 数字显示 127 people died with the virus today, 下 3.1 per cent on last Saturday’s total of 131.
但 42,848 new infections were recorded in the country over the last 24 小时, 向上 8.3 per cent on the 39,567 recorded last week.
It is the fourth day in a row cases have risen across Britain, with officials discovering 75 new cases of the 奥米克戎 variant in England yesterday, taking the UK’s total number up to 134.
And the number of people admitted to hospital with the virus also increased 5.6 per cent in a week to 812 星期二, the latest date data is available for.
另一个 75 cases of the super-mutant Omicron variant were identified in England yesterday, bring the total number of confirmed Omicron infections in England to 104, while the total for the whole of the UK now stands at 134, the UK Health Security Agency (UKHSA) 说过.
Cases of the new variant were identified in the East Midlands, 英格兰东部, 伦敦, 东北, 西北, 东南, South West and West Midlands.
Scotland’s cases today increased by 16 至 29, while Wales announced yesterday afternoon that its first case had been found in Cardiff. No cases have been found in Northern Ireland.
Boris Johnson has placed South Africa and a host of other southern African nations on the ‘red list’ in a bid to slow the variant’s ‘seeding’ 在英国. He has also reimposed face masks in shops, on public transport, and in communal areas of schools in England, and said all close contacts of Omicron cases must self-isolate for ten days.
In South Africa President Cyril Ramaphosa is holding a meeting this weekend. The country remains on alert level one, which only requires face masks to be worn in public places and places some limits on large events.

Official data shows that the proportion of positive Covid tests with a mutation synonymous with the highly-evolved strain is on the rise in the UK. Like Alpha, or the ‘Kent variant’, Omicron has a specific alteration which means it can be detected through PCR tests without the need for genomic sequencing. The proportion of positive tests in England with this so-called S-gene dropout has risen from 0.1 per cent in the past week to 0.3 百分, the equivalent of one in 330. Scientists said the increase in S-gene dropouts suggests there could be hundreds of Omicron cases that are flying under the radar currently
South Africa’s test positivity rate — the number of swabs that detect the virus — is running very high, 然而, with almost a quarter of all swabs picking up the virus.
This suggests there are many more infections in the communtiy that are not being diagnosed.
在英国, the positivity rate is around nine per cent.
President Ramaphosa has so far dodged imposing more restrictions, instead mulling over plans to tell nationals to get two doses of the Covid vaccine.
He has insisted that current restrictions are enough to keep the virus at bay despite surging infection rates.
‘Keep calm and carry on with your Christmas plans’: Oliver Dowden attempts to end confusion over festive advice
Tory Party chairman Oliver Dowden today insisted people should ‘keep calm and carry on’ with their Christmas plans and parties despite Omicron – but Britain’s pubs, hotels, restaurants and clubs already set to lose billions say ‘the damage is already done’ as the cancellations continue.
Mr Dowden insisted the Government had been clear in its guidelines – despite a plethora of ministers offering contradictory and confusing advice – 并表示: ‘There’s a Conservative Party Christmas party still planned’.
He also said that providing Britons abide by mask rules on public transport and in shops, they can kiss anyone they like under the mistletoe.
Boris Johnson has urged businesses not to cancel office parties and proceed with caution when his ministers either told people to cancel, wear masks, take tests and not snog strangers – none of which are in the Government guidelines.
Mr Dowden told Sky News: ‘The message to people, 我认为, is fairly straightforward – which is keep calm, carry on with your Christmas plans. We’ve put the necessary restrictions in place, but beyond that keep calm and carry on.
‘I understand that people have concerns around the new variant. That’s why the Government has taken the sort of measures that we’ve already outlined … we think those are sufficient at this stage and, beyond that, people should continue with their plans as intended.’
Amid confusion about what to do, many of Britain’s biggest employers including the NHS, banks and tech firms have axed festive bashes completely or taken them online. It is now said to be a 50/50 分裂.
The president is expected to face opposition to further restrictions because of the economic ramifications and a local election campaign in early November that paid scant regard to Covid measures.
Professor Mary-Ann Davies, an infectious disease expert at the University of Cape Town, has called on the Government to get more people vaccinated.
She told local newspaper the 周日时报: ‘The single most important thing we can do is to increase vaccine coverage as rapidly as possible in the most vulnerable groups and this is where energies should be directed, rather than at lockdowns at this stage.’
一些 24 per cent of South Africans have got two doses of the Covid vaccine. 在英国, 67 per cent are double-vaccinated.
South Africa has slammed travel bans imposed by western nations on the country and its neighbours, blasting them as an overreaction.
Tourism bosses have described the wave of booking cancellations that it triggered as a ‘nightmare’.
Britain has detected 59 Omicron cases so far, although officials say it is ‘likely’ more will be uncovered in the coming days.
本周早些时候, Ms Sturgeon blamed a Steps concert for an outbreak of the Omicron varaint in Scotland.
The First Minister said six out of the country’s 29 confirmed cases had been linked to the event at the OVO Hydro in Glasgow on November 22, a large concert venue in the city.
No cases have been linked to a second performance by the pop band at the same venue the following night.
今天, Nicola Sturgeon urged people to get vaccinated as she got her Covid booster jab but said she cannot guarantee the programme will be free of ‘glitches’ such as people being turned away from appointments.
Her comments came after she received her booster and flu jabs in Glasgow as Scotland recorded 14 coronavirus-linked deaths and 1,257 new cases in 24 小时.
Ms Sturgeon, who was was given her vaccinations at a sports centre in Easterhouse which is being used as a vaccination site, 说过: ‘Please come forward for your vaccination. It’s the best thing you can do to protect yourself but it is also helping protect around you,’ 她说.
‘If you haven’t had your first or second doses yet, please do that, it is never too late but increasingly our message is to people to get boosted as soon possible.
‘We know that the booster vaccination gives you significant added protection – not just marginal added protection – so it really makes a difference.
‘That was important before the emergence of the new variant, it’s even more important now.’
Like Alpha, or the ‘Kent variant’, Omicron has a specific alteration which means it can be detected through PCR tests without the need for genomic sequencing.
The proportion of positive tests in England with this so-called S-gene dropout has risen from 0.1 per cent in the past week to 0.3 百分, the equivalent of one in 330.
Scientists said the increase in S-gene dropouts suggests there could be hundreds of Omicron cases that are flying under the radar currently.

New images of the Omicron variant’s 32 突变 (剩下) were released yesterday by the Covid Genomics UK Consortium (COG-UK). They show the variant’s three mutations — H655Y, N679K, and P681H, located in the lower right of the image — that could help the virus sneak into the body more easily
Early reports on the ground in southern Africa suggested that most cases were mild or completely asymptomatic. But there has been no age breakdown meaning it is impossible to know whether this is because the strain is simply yet to spread to older people.
The WHO has repeatedly claimed that it is a mild strain. WHO spokesman Christian Lindmeier today told reporters in Geneva: ‘I have not seen reports of Omicron-related deaths yet.
‘We’re collecting all the evidence and we will find much more evidence as we go along.
‘The more countries… keep testing people, and looking specifically into the Omicron variant, we will also find more cases, more information, 和, hopefully not, but also possibly deaths.’
Covid 助推器可能可以防止 Omicron, 科学家说
Covid booster vaccines are likely to offer good protection against the 奥米克戎 变体, experts behind a major new study say — in the first glimmer of hope since the emergence of the super-strain last week.
The body’s T-cell immune response after a third dose suggests they will continue to protect against hospitalisation and death from the new strain, according to the Government-funded trial.
T-cells are thought to provide longer lasting and broader protection than antibodies which deliver an initial higher boost of protection but also see that defence fade faster over time.
Professor Saul Faust, trial lead and director of the NIHR Clinical Research Facility at University Hospital Southampton NHS Foundation Trust, 说过: ‘Even though we don’t properly understand its relation to long-term immunity, the T cell data is showing us that it does seem to be broader against all the variant strains, which gives us hope that a variant strain of the virus might be able to be handled, certainly for hospitalisation and death if not prevention of infection, by the current vaccines,’ Professor Faust said.
He said T cell response was not just focused on the spike protein but ‘are recognising a much broader range of antigens that might… be common to all of the variants.’
Asked specifically about Omicron, 他说: ‘Our hope as scientists is that protection against hospitalisation and death will remain intact.’
Samples from the study have now been passed to the UK Health Security Agency (UKHSA) to look at how well the Omicron variant can be neutralised by vaccines.
But Dr Kall said she was ‘sceptical’ about claims the new strain causes less severe disease.
Writing on Twitter, 她说: ‘I am highly sceptical it could be more mild. I think the best case is it’s equivalent in severity to Delta… but you’ll see milder symptoms now, than Delta when it emerged, because many more people have immunity now.’
A pre-print published yesterday suggested Omicron was around three times more likely to re-infect people who had had Covid before.
South African researchers said there had been 35,670 reinfections since the beginning of the pandemic, and the risk of reinfection was 0.7 per cent during the country’s Beta-fuelled second wave last winter and Delta wave in the summer.
But the risk of catching the virus again has recently spiralled to at least 2.4.
Scientists from Stellenbosch University, near Cape Town, said the findings suggested Omicron was better able to evade immunity in people who had already been infected than other variants which were suppressed by immunity.
A pre-print paper means it has not yet been reviewed by other scientists, who double-check its findings.
Microbiologist at Reading University Dr Simon Clarke said the data was the ‘first indication’ that Omicron could get around immunity from previous Covid infection.
他说: ‘There are a few caveats in this work, such as not having definitively confirmed that it was indeed Omicron that was causing the reinfection, but they were able to determine that the increased transmission of Beta or Delta variants was not a result of immune evasion.
‘There is no indication as to how this immune evasion happens, although it can be presumed to be because of decreased antibody binding to Omicron’s mutated spike protein.’
他加了: ‘Omicron has blown a big hole in the controversial argument that we should simply allow the infection to spread in an attempt to create immunity.
‘Herd immunity which now seems like nothing more than a pipe dream. We await a further indication as to whether Omicron has any ability to evade vaccine induced immunity.’
Infectious diseases expert at the University of East Anglia Professor Paul Hunter said: ‘The implications of this paper are that Omicron will be able to overcome natural and probably vaccine induced immunity to a significant degree.
'但, the degree is still unclear though it is doubtful that this will represent complete escape.’
他加了: ‘It remains the case that the extra value of the booster vaccination dose remains the most important step that we can take to reduce the probability of severe disease.
‘I suspect new targeted vaccinations will be developed against omicron but it the infection spreads globally as rapidly as it seems to be taking off in South Africa then most of us may already have had the infection by the time a new vaccine is available.’
The variant has been spotted in more than 30 countries worldwide and is likely to have been spreading for weeks before South Africa raised the alarm. The Netherlands detected a case one week earlier, while Nigeria found its first case in a sample taken in October.
