Indian delegation to G7 summit in London ‘goes into self-isolation’

May 5, 2021 Ava

The Indian delegation to the G7 foreign ministers’ summit in London has gone into self-isolation after positive coronavirus cases.

Government sources confirmed to MailOnline that two members of the delegation have tested positive, and the whole group is now believed to be in isolation as a precaution.

India is not part of the G7 but they are attending the gathering – the first major face-to-face meeting since the pandemic erupted. The delegation is thought to have been exempted from quarantine rules, but have been tested daily.

The cases were picked up by Public Health England last night, before the delegation was due to join G7 meetings at Lancaster House today.

Priti Patel met the Indian foreign minister Subrahmanyam Jaishankar at the Home Office yesterday, but he is not believed to be one of the positive cases.

Another government source said PHE had advised that the UK delegation does not need to isolate, as social distance was observed and masks were worn.

Dr Jaishankar tweeted this morning: ‘Was made aware yesterday evening of exposure to possible Covid positive cases.

‘As a measure of abundant caution and also out of consideration for others, I decided to conduct my engagements in the virtual mode. That will be the case with the G7 Meeting today as well.’

The revelation threatens to throw the summit into chaos. It was meant to be Covid secure and demonstrate that international diplomacy can get back to normal ahead of the full G7 summit in Cornwall next month.

That is due to be attended by US president Joe Biden among others.

Boris Johnson held talks with Indian PM Narendra Modi over video link yesterday.

The news came amid rising fears about Indian Covid variants, with figures suggesting they now make up one in 10 cases in London.

Data from the Sanger Institute, which analyses positive swabs for different variants, suggest the mutant strains spread widely during April.

WHAT DO WE KNOW ABOUT THE INDIA VARIANTS?

Real name: B.1.617 – now divided into B.1.617.1; B.1.617.2; B.1.617.3

When and where was it discovered?

The variant was first reported by the Indian government in February 2021.

But the first cases appear to date back to October 2020.

Its presence in the UK was first announced by Public Health England on April 15. There have since been at least 400 cases spotted in genetic lab testing.

What mutations does it have?

It has 13 mutations that separate it from the original Covid virus that emerged in China — but the two main ones are named E484Q and L452R.

Scientists suspect these two alterations can help it to transmit faster and to get past immune cells made in response to older variants.

PHE officials said it has split into three distinct virus types, with types 1 and 3 both having the E484Q mutation but type 2 missing the change, despite having all the other hallmarks of the variant.

Is it more infectious and can it evade vaccines?

The L452R mutation is also found on the Californian variant (B.1.429), even though the two evolved independently. It is thought to make the American strain 20 per cent more infectious than the original Wuhan version – even with the extra 20 per cent it is likely slower than the Kent variant.

The E484Q mutation is very similar to the one found in the South African and Brazil variants known as E484K, which can help the virus evade antibodies.

The South African variant is thought to make vaccines about 30 per cent less effective at stopping infections, but it’s not clear what effect it has on severe illness.

Professor Sharon Peacock, of PHE, claimed there was ‘limited’ evidence of E484Q’s effect on immunity and vaccines. Lab studies have suggested it may be able to escape some antibodies, but to what degree remains uncertain.

Early research suggests both the AstraZeneca vaccine, known as Covishield in India, and the Pfizer jab, still work against the variant, as well as India’s own jab, Covaxin. A paper published by SAGE last week suggested two doses of the Pfizer vaccine is good enough to protect against all known variants.

How deadly is it? Scientists still don’t know for sure. But they are fairly certain it won’t be more deadly than the current variants in circulation in Britain.

This is because there is no evolutionary benefit to Covid becoming more deadly. The virus’s sole goal is to spread as much as it can, so it needs people to be alive and mix with others for as long as possible to achieve this.

And, if other variants are anything to go by, the Indian strain should not be more lethal.

There is still no conclusive evidence to show dominant versions like the Kent and South African variants are more deadly than the original Covid strain – even though they are highly transmissible.

Doctors in India claim there has been a sudden spike in Covid admissions among people under 45, who have traditionally been less vulnerable to the disease.

There have been anecdotal reports from medics that young people make up two third of new patients in Delhi. In the southern IT hub of Bangalore, under-40s made up 58 percent of infections in early April, up from 46 percent last year.

There is still no proof younger people are more badly affected by the new strain.

Should we be worried?

Scientists are unsure exactly how transmissible or vaccine-resistant the Indian variant is because it hasn’t been studied thoroughly.

The fact it appears to have increased infectivity should not pose an immediate threat to the UK’s situation because the current dominant Kent version appears equally or more transmissible.

It will take a variant far more infectious strain than that to knock it off the top spot.

However, if the Indian version proves to be effective at slipping past vaccine-gained immunity, then its prevalence could rise in Britain as the immunisation programme squashes the Kent variant.

The UK currently classes the Indian strain as a ‘Variant Under Investigation’, a tier below the Kent, South African and Brazilian variants. But there are calls to move it up to the highest category.

Scientists tracking the constantly-evolving virus say it’s still not clear if India’s third wave has been caused by the variant, or if it emerged at the same time by coincidence.

G7 foreign ministers were welcomed by Foreign Secretary Dominic Raab at Lancaster House this morning for the second day of the summit.

Mr Raab, wearing a face mask, arrived at the venue ahead of officials from France, Germany, Italy, Japan, Canada, the US and the EU.

He greeted them in the courtyard, including guests invited as part of the UK’s tilt to the Indo-Pacific region, with an elbow bump replacing the usual handshake.

Across the UK the three different Indian variants — which are all genetically similar — account for 2.4 per cent of all infections in the most recent week, ending April 17, up 12-fold from just 0.2 per cent at the end of March.

But the same figures suggest one in 10 cases in London were caused by the B.1.617 variants.

Data also showed the proportion ranged as high as 46 per cent in Lambeth and 36 per cent in Harrow – but the figures are based on tiny numbers of cases so clusters or super-spreading events have an amplified effect that may fade quickly.

Not much is known about the Indian variant, linked to an explosion of cases in India that has seen dead bodies spill out onto the street and mass cremations taking place in public car parks because hospitals have ran out of oxygen.

But one scientist said the most recent data – which doesn’t include travellers’ tests and is intended to be a snapshot of community infection rates – suggests it could be ‘outcompeting’ the Kent variant, which is dominant in the UK.

The proportion of cases being caused by the variants is rising whereas it would be expected to fall alongside the Kent variant if they were equally as fast-spreading.

But it could also just be a coincidence that outbreaks were happening where the variants were present, said Professor Christina Pagel, a mathematician at University College London and member of the Independent SAGE panel of experts.

There are too few cases in the UK to actually be able to tell anything about how the variants behave, Professor Pagel added, and not enough genetic testing in India.

Public Health England’s Dr Susan Hopkins said the agency was ‘still investigating’ the cases and added there is ‘no evidence that the variant causes more severe disease or renders the vaccines currently deployed any less effective’.

‘The numbers are still low but certainly in London right now, B.1.617 and its subtypes are the only variant that appears to be growing,’ Professor Pagel told MailOnline yesterday.

‘That could be because it is outcompeting other strains, including the dominant Kent strain, or it could be circumstantial in that there were some spreading events that happened that, just by chance, were the Indian strain.

‘However, I think the experience of India and now its neighbours do provide plenty of reason to be cautious and assume that B.1.617 is more transmissible.’

PHE has designated the Indian strains ‘variants under investigation’ because they are not well understood.

The Kent and South Africa variants are ‘variants of concern’ because they are known to spread faster and escape some types of immunity – this means officials do surge testing to stamp out the South Africa variant when it’s found, but they don’t currently for India.

Another 357,229 Covid cases and 3,449 new fatalities were recorded by the health ministry in India yesterday but medics believe the real figures could be between five and 10 times higher.

Some have suggested the fast-spreading Kent variant could be behind the surge – similar patterns were seen when it took hold in the UK and Europe.

But others say it was a perfect storm of rules that weren’t tight enough, people’s inability to keep social distancing and also new variants emerging.

Data from the Wellcome Sanger Institute suggests it detected 100 test samples with the Indian variants in the most recent week, up from 52 in the week to April 10. This does not include tests from people travelling internationally.

During that time the proportion of national cases they accounted for rose from one per cent to 2.4 per cent. Dr Pagel also said the proportion nationally was slightly higher, at around 4 per cent.

This ate into the market share of the Kent variant, which fell from 97.8 to 96.2 per cent of cases. The Brazil and South Africa variants together account for less than one per cent.

They have now been found in dozens of local authorities across the country with hotspots in London and the Midlands, and Public Health England has officially confirmed 400 infections caused by the viruses.

As well as Lambeth (46 per cent of cases) and Harrow (36 per cent), the Indian variants also made up large proportions in Eastleigh, Hampshire (31 per cent); Bromley (25 per cent); Bolton (24 per cent); Stafford, Haringey and Hounslow (22 per cent).

Professor Pagel: ‘It rapidly became dominant in India and, again the sequenced data there is sparse, but early modelling shows that it might well be more transmissible than our B.117 Kent strain.

‘What we have also seen in India is that B.1.617.2 is becoming the dominant subtype – exactly the same pattern we see here in the UK.

‘While this could reflect the situation in India through importation, the Sanger data tries to exclude travel related cases or surge testing and we still the rise of B.1.617.2 in that.

‘So we cannot be definitive. But that doesn’t mean we should be complacent either – as so often with Covid, waiting to be absolutely sure is waiting too long.’

Although the Sanger Institute data tries to filter out test results from people who have travelled internationally, its numbers likely reflect cases that are parts of clusters than began with a traveller.

India is now on Britain’s red list, meaning only UK residents and citizens are allowed to make the journey into the country.

They must quarantine for 10 days in a hotel and test themselves three times – before departure and then twice during self-isolation.
