The potentially massive scale of unrecorded covid-19 deaths in India’s second wave means the official world death toll may be a significant underestimate

India’s death toll from covid-19 may be six to seven times greater than that officially recorded. The country’s records say that nearly half a million people have died from coronavirus infections so far, but the latest study estimates the real figure is 3.2 million deaths up to July last year. 

If correct, this means the worldwide death toll from the coronavirus would be pushed up from 5.4 to 8.1 million – although other countries may also have underestimated their death rates. “This may require substantial upward revision of the World Health Organization’s estimates of cumulative global covid mortality,” Prabhat Jha at the University of Toronto and colleagues say in their paper.

India experienced a huge second wave of coronavirus infections in the first half of 2021, leaving hospitals overwhelmed and a national shortage of oxygen supplies. In common with many other low and middle-income countries, India does not have good systemic methods for recording causes of death, especially those that occur in rural areas. For instance, Jha’s team say that in 2020, an estimated eight in ten deaths did not involve medical certification, which is standard procedure in richer countries.

Jha’s team reached the figure of 3.2 million by using government data on all-cause mortality and an ongoing telephone survey of 140,000 adults across the country, which asked people about covid-19 symptoms and deaths in their households.

Omicron continues to surge in the UK and other European countries

More than 24 NHS trusts have declared critical incidents in England after being overwhelmed by omicron patients. It means priority services may currently be under threat at one in six trusts in England. 

In the UK there are currently 17,276 patients in hospital with the virus, according to the latest daily figures – the highest figure since last February. Yesterday close to 200,000 people tested positive for coronavirus. 

“The sheer volume of covid cases, rising hospital admissions that have increased to over 15,000 and widespread staff absences that are as high as 10 per cent in some trusts are all combining to place front-line NHS services under enormous strain,” said Matthew Taylor, the head of the NHS Confederation

Other countries in Europe are also facing unprecedented numbers of daily coronavirus cases. In France, 332,252 coronavirus cases were recorded yesterday. There were also over 20,000 covid-19 patients in hospital yesterday – the country’s highest figure since late May. 

Italy also reported a record number of new coronavirus cases for the second day in a row. The latest total was 189,109. Meanwhile, Turkey hit a record high of 66,467 cases yesterday.

SARS-CoV-2 variant found in France was identified in November 

A coronavirus variant first discovered in France in late 2021 has had a lot of chances to spread but did not, according to an official from the World Health Organization (WHO).

The variant has been on the intergovernmental body’s radar since November, Abdi Mahamud, a WHO incident manager said at a press briefing yesterday according to Bloomberg.

The variant was discovered around the same time as omicron.

Known as the B.1.640.2 variant, it caused at least 12 people to fall ill in Marseilles in November. “[It is] too early to speculate on virological, epidemiological or clinical features of this… variant based on these 12 cases,” say researchers in a preliminary analysis of the variant’s genome. The variant has 46 mutations and 13 deletions in its genome, say the team.

“This virus has had a decent chance to cause trouble but never really materialised as far as we can tell”, tweeted Tom Peacock, at Imperial College London, who was not involved in the analysis.

Multiple variants of the virus have evolved since the pandemic began but only a handful have gone on to spread widely. The highly-infectious omicron variant is currently sweeping through Europe, and France yesterday recorded 271,686 covid-19 infections, a national record.

Normal life will be made harder for unvaccinated people in France, French president Emmanuel Macron told Le Parisien yesterday.

“We need to tell them, from 15 January, you will no longer be able to go to the restaurant. You will no longer be able to go for a coffee, you will no longer be able to go to the theatre. You will no longer be able to go to the cinema.”

Other coronavirus news

The tennis player Novak Djokovic has faced backlash after yesterday saying on Instagram that he had received a medical exemption to take part in the Australian Open. Only people who are fully vaccinated can currently visit Australia. Djokovic has not spoken about his vaccination status, but has previously expressed anti-vaccination sentiments.

The organisers of the tournament, which starts on 17 January, say the athlete has not been given special treatment. Australia’s prime minister Scott Morrison said the Serbian player would need to show a genuine medical exemption to enter the country unvaccinated.

Delhi will impose a weekend curfew to curb soaring omicron cases in the Indian city. All non-essential activity will be banned from Friday night (7 January) to Monday morning (10 January). The curbs are in addition to a nighttime curfew that has been in place since late December from 11pm and 5am. Cinemas and gyms have also been closed since last week.

Staff shortages force health service providers to enact emergency measures

At least six National Health Service trusts in England have declared critical incidents as a result of staff shortages caused by covid-19.

A critical incident means that the healthcare providers believe they may no longer be able to provide a range of critical services, and the status enables them to call for help from staff and other organisations. University Hospitals of Morecambe Bay and United Lincolnshire Hospitals are among the trusts implementing emergency measures.

The chief executive of the NHS Confederation, Matthew Taylor, wrote in a blogpost that many parts of the health service are currently in “a state of crisis”, while community and social care services are at “breaking point”. 

On a visit to a vaccination centre in Buckinghamshire yesterday, Boris Johnson, the UK prime minister, said: “I think we’ve got to recognise that the pressure on our NHS, on our hospitals, is going to be considerable in the course of the next couple of weeks, and maybe more.”

Meanwhile, as children return to schools today, the government has recommended the wearing of face masks in secondary classrooms in England, as is already advised in Scotland, Wales and Northern Ireland. Head teachers have warned that high levels of staff absences could lead to children being sent home to learn remotely.

Covid-19 cases may have plateaued in London and could start to fall in other parts of the UK within 3 weeks, an epidemiologist and government adviser has said. Neil Ferguson, of Imperial College London, told BBC Radio 4’s Today programme that infection rates in the capital appear to be stabilising in the 18 to 50 age group, which has been driving the omicron epidemic. 

“With an epidemic which has been spreading so quickly and reaching such high numbers, it can’t sustain those numbers forever, so we would expect to see case numbers start to come down in the next week; [they] may be already coming down in London, but in other regions a week to 3 weeks,” he said.

“Whether they then drop precipitously, or we see a pattern a bit like we saw with delta back in July of an initial drop and then quite a high plateau, remains to be seen. It’s just too difficult to interpret current mixing trends and what the effect of opening schools again will be.”

In the US, thousands of schools have delayed the start of term or switched to remote learning amid surging cases caused by the omicron variant. New York City’s mayor has vowed to keep schools open despite soaring infection rates, in contrast to cities such as Milwaukee, Cleveland and Detroit. Nationwide, the number of patients in hospital with covid-19 increased by 40 per cent in the past week, according to Reuters.

The US Food and Drug Administration has authorised a third dose of the Pfizer/BioNTech vaccine to be given to children aged 12 to 15. A panel advising the US Centers for Disease Control and Prevention will now decide whether to recommend booster shots in this age group.

Immunity offered by vaccines wanes more quickly with omicron, finds UK study

The protection conferred by booster vaccines against the omicron variant begins to wane within 10 weeks, according to a briefing released by the UK Health Security Agency (UKHSA).

Based on an analysis of 147,597 delta and 68,489 omicron cases, the agency found that the Oxford/AstraZeneca, Pfizer/BioNTech and Moderna vaccines are less effective against omicron than delta. For people who had two initial doses of the Oxford/AstraZeneca vaccine, the UKHSA estimates that Pfizer/BioNTech or Moderna boosters are around 60 per cent effective at preventing symptomatic infections from omicron 2 to 4 weeks after the third dose, but this falls to 35 to 45 per cent by 10 weeks. For those who had two initial doses of Pfizer/BioNTech, protection falls from 70 per cent at 2 to 4 weeks to 45 per cent at 10 weeks after a Pfizer booster, but stays around 70 to 75 per cent up to 9 weeks after a Moderna booster.

The UKHSA report also estimates that someone infected with omicron is 50 to 70 per cent less likely to be admitted to hospital, compared with delta. This is based on a preliminary analysis of 114,144 omicron cases and 461,772 delta cases occurring between 22 November and 19 December. The difference is somewhat larger than suggested by a study published by Imperial College London on Wednesday, which reported a 15 to 20 per cent lower risk.

However, modelling suggests that the severity of omicron would need to be around 90 per cent lower to avoid similar levels of hospital admissions to previous waves, according to minutes from a meeting of the UK government’s Scientific Advisory Group for Emergencies on Monday.

“What we have got now is a really fine balance between something that looks like a lower risk of hospitalisation – which is great news – but equally a highly transmissible variant and one that we know evades some of our immune defences, so it is a very balanced position,” Jenny Harris, chief executive of UKHSA, told the Today programme on BBC Radio 4.

The UK recorded 119,789 new cases of covid-19 yesterday, setting another record. The Office for National Statistics estimates that 1.4 million people in the UK had the virus in the week ending 16 December, the highest number since comparable figures began in autumn 2020.

Healthcare workers in the US who have tested positive for covid-19 but do not have symptoms can stop isolating after seven days instead of 10, if they test negative for the virus, under new guidelines from the Centers for Disease Control and Prevention.

Italy has banned public new year’s eve celebrations as well as all concerts and open air events until 31 January, aiming to curb a rise in infections driven by the omicron variant. Mask wearing will also be compulsory in outdoor public places under new rules.

Australia will cut the interval between second doses and booster shots from 5 months to 4 from 4 January, and then to 3 months on 31 January.

Solar storms that disrupt Earth’s magnetic field may cause up to 5500 heart-related deaths in the US in a given year.

The sun goes through cycles of high and low activity that repeat approximately every 11 years. During periods of high activity, it blasts out charged particles and magnetised plasma that can distort Earth’s magnetic field.

These so-called solar storms can cause glitches in our power grids and bring down Earth-orbiting satellites. A handful of studies have also hinted that they increase the risk of …

UK Covid infection rate rising, with more than a million cases in England | Coronavirus

Published

on

Coronavirus infections are rising in the UK, figures have revealed, with experts noting the increase is probably down to the more transmissible BA.4 and BA.5 Omicron variants.

The figures from the Office for National Statistics (ONS), based on swabs collected from randomly selected households, reveal that in the week ending 11 June an estimated one in 50 people in the community in England are thought to have had Covid – around 1.13 million people.

The figure is even higher, at one in 45, in both Wales and Northern Ireland, while it was highest in Scotland where, in the week ending 10 June, one in 30 people are thought to have been infected.

While the figures remain below the peak levels of infection seen earlier this year, when around one in 13 people in England had Covid, the findings are a rise on the previous week where one in 70 people in England were thought to be infected. Furthermore, the data reveals increases in all regions of England, except the north-east, and across all age groups.

Experts say that a key factor in the increase is probably the rise of the Covid variants of concern BA.4 and BA.5.

“Infections have increased across all four UK nations, driven by rising numbers of people infected with the BA.4 and BA.5 Omicron variants,” said Kara Steel, senior statistician for the Covid-19 Infection Survey.

While Steel said it remained too early to say if this was the start of another wave, others have warned it may already have begun, with increased mixing and travelling among other factors fuelling a rise in cases.

Among concerns scientists have raised are that BA.4, BA.5 and another variant on the rise, BA.2.12.1, replicate more efficiently in human lung cells than BA.2.

Prof Azra Ghani, an epidemiologist at Imperial College London, said the latest figures were not surprising, and might rise further.

“This increase in infection prevalence is likely due to the growth of the BA.4 and BA.5 Omicron subvariants, which as we have seen elsewhere in Europe, appear to be able to escape immunity generated from previous Omicron subvariants,” she said.

“It is therefore possible that we will continue to see some growth in infection prevalence in the coming weeks and consequently an increase in hospitalisations, although these subvariants do not currently appear to result in any significantly changed severity profile. This does however serve as a reminder that the Covid-19 pandemic is not over.”

NHS to offer women in England drug that cuts recurrence of breast cancer | Breast cancer

Published

on

Thousands of women in England with breast cancer are to benefit from a new pill on the NHS which reduces the risk of the disease coming back.

The National Institute for Health and Care Excellence (Nice) has given the green light to abemaciclib, which cuts the chance of breast cancer returning after a patient has had surgery to remove a tumour.

Trials showed that patients who had the drug with hormone therapy had a more than 30% improved chance of their cancer not coming back after surgery, compared with hormone therapy alone.

“It’s fantastic thousands of women with this type of primary breast cancer will now have an additional treatment option available on the NHS to help further reduce the risk of the disease coming back,” said Delyth Morgan, the chief executive of charity Breast Cancer Now.

“The fear of breast cancer returning or spreading to other parts of their body and becoming incurable can cause considerable anxiety for so many women and their loved ones.

“New effective treatments such as abemaciclib, which can offer more women the chance to further reduce the risk of the disease recurring, are therefore extremely welcome and this is an important step change in the drug options available for this group of patients.”

The twice-a-day pill is suitable for women with hormone receptor-positive, HER2-negative, node-positive early breast cancer at high risk of recurrence who have had surgery. About 4,000 women will benefit initially, Nice said.

Helen Knight, the interim director of medicines evaluation at Nice, said the draft recommendation came less than a month after abemaciclib received its licence.

“The fact that we have been able to produce draft recommendations so quickly is testament to the success of our ambition to support patient access to clinically and cost effective treatments as early as possible,” said Knight. “Until now there have been no targeted treatments for people with this type of breast cancer.

“Abemaciclib with hormone therapy represents a significant improvement in how it is treated because being able to have a targeted treatment earlier after surgery will increase the chance of curing the disease and reduce the likelihood of developing incurable advanced disease.”

Abemaciclib works by targeting and inhibiting proteins in cancer cells which allow the cancer to divide and grow. It normally costs £2,950 for a packet of 56 150mg-tablets, but the manufacturer, Eli Lilly, has agreed an undisclosed discounted price for NHS England.

“Thanks in part to this latest deal struck by NHS England, NHS patients will be able to access another new targeted drug for a common and aggressive form of breast cancer,” said Prof Peter Johnson, the cancer director of NHS England.

“Abemaciclib, when used alongside a hormone therapy, offers a new, doubly targeted, treatment option, helping to increase the chances of beating the cancer for good, as well as meeting the NHS’s commitment to delivering improved cancer care under our long-term plan.”
