South Africa's Covid cases soar 467% 一週間で 16,055 感染症

South Africa’s daily Covid cases soar 467% 一週間で 16,055 新しい感染症と入院が急増 365% に 279 amid Omicron wave — as country warns its R rate could be 3.5

  • The country’s National Institute for Communicable Diseases recorded 16,055 cases in the last 24 時間
  • これは 468 per cent jump on a week ago when 2,828 were recorded, and up 1,900 per cent in a fortnight
  • Hospitalisations also surged 360 per cent in a week after 279 were recorded today compared to 60 last Friday
  • South Africa is seeing a meteoric rise in cases as the Omicron variant spreads rapidly in the country
  • Covid cases in Omicron-stricken 南アフリカ spiralled almost five-fold in a week today and hospitalisations rocketed more than 360 per cent — as officials warn the R rate in the epicentre may be as high as 3.5.

    The country’s National Institute for Communicable Diseases recorded another 16,055 Covid cases in the last 24 hours — with the vast majority in epicentre Gauteng province.

    This was a jump of 468 per cent on a week ago when 2,828 infections were announced, and up 1,900 per cent on a fortnight ago when just 789 infections were registered.

    Hospitalisations also surged after 279 were recorded today, に比べ 60 last Friday. And deaths more than doubled after 25 were recorded compared to 12 1週間前.

    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.

    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 その他. イギリスで, 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 ‘worsethan 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 59 Omicron cases to date.

    Boris Johnson has placed South Africa and a host of other southern African nations on the ‘red listin a bid to slow the variant’s ‘seeding’ イギリスで. 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.

    ‘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 onwith their Christmas plans and parties despite Omicronbut Britain’s pubs, ホテル, restaurants and clubs already set to lose billions say ‘the damage is already doneas the cancellations continue.

    Mr Dowden insisted the Government had been clear in its guidelinesdespite a plethora of ministers offering contradictory and confusing advice – そして、言いました: ‘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 strangersnone of which are in the Government guidelines.

    Mr Dowden told Sky News: ‘The message to people, おもう, is fairly straightforwardwhich 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 outlinedwe 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 スプリット.

    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 (11,553 新しいケース), where they surged 431 per cent in a week.

    The second-highest number of new infections were recorded in the Western Cape (957 ケース, アップ 588 パーセント), followed by KwaZulu-Natal (897 ケース, アップ 730 パーセント) and the North West (805 ケース, アップ 594 パーセント).

    Daily infections are spiralling in South Africa which is now recording almost 7,000 cases a day on average.

    But they are rising from a much lower base than in other countries like the UK, where cases today broke through 50,000 a day for the second time in 48 時間.

    South Africa’s test positivity rate — the number of swabs that detect the virus — is running very high, しかしながら, 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.

    イギリスで, the positivity rate is around nine per cent.

    Scientists are working at breakneck speed to establish whether Omicron is more transmissible and deadly than other mutant strains. But they say it could still be at least a week before reliable estimates start to emerge.

    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 countrieskeep testing people, and looking specifically into the Omicron variant, we will also find more cases, more information, そして, hopefully not, but also possibly deaths.

    But Dr Kall said she is ‘scepticalabout claims the new strain causes less severe disease.

    Twitterで書く, 彼女は言いました: ‘I am highly sceptical it could be more mild. I think the best case is it’s equivalent in severity to Deltabut 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 indicationthat Omicron could get around immunity from previous Covid infection.

    Covidブースタージャブはオミクロンから保護する可能性があります, 科学者は言う

    Covid booster vaccines are likely to offer good protection against the オミクロン バリアント, 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.

    It also supports the UK’s decision to use ファイザー または モダン as boosters, with mRNA jabs turbocharging antibody and T-cell responses the most.

    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, 前記: ‘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 mightbe common to all of the variants.

    Asked specifically about Omicron, 彼は言った: ‘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.

    彼は言った: ‘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.

    彼が追加した: ‘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.

    'だが, the degree is still unclear though it is doubtful that this will represent complete escape.

    彼が追加した: ‘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.

    いくつか 51,402 people in the country took a Covid test and 22.4 per cent of them tested positive for the virus. For comparison, 38,075 per cent of tests taken on the same day last week and 6.5 per cent were positive.

    その間, Covid hospital admissions nearly tripled in a week, but deaths have fallen 64 パーセント.

    But despite fears about Omicron, South Africa is still recording far fewer overall Covid cases compared to its population size than both the UK and US.

    Figures from the Oxford University research platform Our World in Data show South Africa has 63 cases per million people compared to 638 in the UK and 257 アメリカ合衆国で. Cases are rising sharply in South Africa but are starting at a low base.

    Professor Anne von Gottberg, a clinical microbiologist at the NICD, revealed at a World Health Organization conference yesterday the variant was behind 75 per cent of cases nationally and it ‘does look like there is a predominance of Omicron throughout the country’.

    Five of the country’s nine provinces have confirmed Omicron cases and officials expect its prevalence to be high in the remaining four areas where positive samples have not yet been sequenced. There have only been 183 confirmed cases of the strain because only a handful of positive samples are analysed for variants.

    The variant has been spotted in more than 20 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.

    It was even in the UK before it was first spotted by scientists last week, with nine cases in Scotland on November 20, causing speculation the strain was imported from the COP 26 climate conference or a rugby game at Murrayfield Stadium against South Africa.

    New images of the strain’s 32 mutations 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.

    And the graphic shows a group of mutations — K417N, S477N, Q498R, E484A and N501Y — that are thought to help Omicron dodge antibodies that usually help fight off the virus.

    And N501Y, which was previously seen on Alpha, Beta and Gamma, also helps the virus bind to the body’s cells more easily, allowing for it to enter the body and replicate more efficiently.

    その間, it has 26 mutations on its spike protein — that haven’t been seen in previous variants and scientists are still probing whether they will have any impact on how fast it can spread.
