Boris Johnson is today set to announce a four-week delay to the end of the Covid lockdown roadmap as experts fear the now-dominant Indian ‘Delta’ variant is on the cusp of triggering a third wave.
Cases have spiked 50 per cent in a week across the UK and the number of people needing hospital treatment for Covid is rising slowly in its wake, with more than 1,000 people now on wards with the virus.
Infections are mostly in the young, with rates up to seven times higher among people in their 20s than in the over-80s, and scientists and ministers are still confident that vaccines will keep a lid on the death toll.
But a single dose is no longer enough to protect most people from catching Covid and Mr Johnson must buy the NHS more time to get second jabs out to millions more middle-aged people, who are still at risk of hospitalisation.
The PM is expected to announce that curbs such as large event number limits, social distancing and unlimited indoor mixing will have to stay until at least mid-July and potentially until England’s school summer holidays.
He hinted strongly at the delay when he said on Friday: ‘What everybody can see very clearly is that cases are going up and in some places hospitalisations are going up… We will be driven by the data, we will be looking at that and setting it out on Monday.’
Here is a look at the data that may have spooked him:
The trend of total number of people in hospital has remained relatively flat, fluctuating between 800 and 1,100 for the past month but creeping upwards in the most recent week. Experts say the current surge in cases will see it tick up in the coming days and weeks.
Public Health England data showed that in the week ending June 6 the highest infection rate was 121 cases per 100,000 people among those aged 20 to 29. Rates were also high in teenagers (99 per 100,000) and adults in their 30s (73). They are significantly lower among older age groups
CASES ARE RISING ACROSS UK BUT BIGGEST SPIKES IN UNDER-30s
Coronavirus cases have undeniably been rising in the UK, and quickly, in recent weeks after the ending of most lockdown rules on May 17 coincided with the takeover of the Indian variant.
The average number of positive tests announced each day is now above 7,000 for the first time since the tail end of the second wave in March, after 7,490 cases were confirmed yesterday after 8,125 on Friday.
There were 50,017 cases confirmed between Monday and Sunday last week, a 50 per cent spike from 33,496 the week before.
But a ray of hope among the rising infections is the fact that cases are up to 17 times higher among young adults than they are in the at-risk elderly, suggesting vaccines are protecting older people.
Public Health England data showed that in the week ending June 6 the highest infection rate was 121 cases per 100,000 people among those aged 20 to 29. Rates were also high in teenagers (99 per 100,000) and adults in their 30s (73).
But they were significantly lower in the middle-aged and elderly, with the lowest rate in over-70s, at 7 per 100,000, followed by 14 per 100,000 among people in their 60s and 32 per 100,000 in people in their 50s.
And while the rate had doubled in just a week in people in their 20s, it rose by only 17 per cent in the over-80s, showing most of the surging epidemic at the time was in young people.
HOSPITAL ADMISSIONS ARE CREEPING UP WITH VARIANT HOTSPOTS LEADING THE WAY
Hospital admissions are creeping up across the UK and more notably in Delta variant hotspots.
The increase has been significantly slower than cases – there was a 15 per cent increase in the most recent week, from 875 new admissions by June 1 to 1,008 in the week to June 8 – but this is likely an effect of the lag between someone getting infected and then getting sick enough to need hospital treatment.
The real test of how well vaccines will taking pressure off hospitals will come in the next week or two, when there has been enough time – two to three weeks – since the spike in cases to see what happens.
Professor Neil Ferguson, Imperial College London epidemiologist and member of SAGE, said scientists were hoping the ratio of cases to hospital admissions could be cut by 85 per cent from the pre-jab rate of around nine per cent.
In the most recent data, for June 8, there were 187 people admitted to hospital with Covid in the UK, the highest since April 14. By Thursday, June 10, there were a total of 1,089 patients in hospital.
The trend of total number of people in hospital has remained relatively flat, fluctuating between 800 and 1,100 for the past month but creeping upwards in the most recent week. Experts say the current surge in cases will see it tick up in the coming days and weeks.
Places where infection rates with the Delta variant are comparatively high – Bedfordshire, London, Birmingham, Manchester and East Lancashire – had the highest admission rates in the most recent data but even those, the worst-hit hospitals, still had only five patients admitted on June 6.
They also have the most people in hospital in total, with 44 Covid patients on wards in Manchester University NHS Trust on June 8. This was the highest in the country and up almost 60 per cent in a week from 28 on June 1.
Inpatient numbers were rising in all but three of the areas with the most patients – falling only in Bolton and Croydon, and flat at King’s College London, while rising in Imperial College London, East Lancashire, Bedfordshire, Salford Royal in Manchester, Southampton and Birmingham.

INTENSIVE CARE CLOSE TO 2021 LOW BUT RISING SLOWLY WITH NORTH WEST WORST HIT
The number of patients with Covid in intensive care remains low in the UK, with only 158 people critically ill in hospital by June 10.
This figure rose slightly compared to previous weeks but the trend has been broadly flat – the lowest point of 2021 was 119 on May 29, just two weeks ago, after it fell from over 4,000 in late January.
More detailed information for England, up to June 8, showed that 47 out of a total 140 intensive care patients were all in the North West.
Just two Indian variant hotspots East Lancashire and Bolton hospitals accounted for 21 of these patients – 15 per cent of the country’s total, or one in seven.
The delay between cases and the need for intensive care is even longer than it is between people getting infected and getting admitted to a general hospital ward, so these numbers could begin increasing in the coming weeks.
But the vaccines are also expected to have an effect on the number of people who become gravely ill. While the jab should stop most people from ending up in hospital at all, even those who do end up in hospital do not seem to be as sick as they used to be.
Chief of the NHS Providers union, Chris Hopson, said last week: ‘What chief executives are consistently telling us is that it is a much younger population that is coming in, they are less clinically vulnerable, they are less in need of critical care and therefore they’re seeing what they believe is a significantly lower mortality rate which is, you know, borne out by the figures.
‘So it’s not just the numbers of people who are coming in, it’s actually the level of harm and clinical risk.’
GOVERNMENT MUST BUY MORE TIME FOR VACCINE ROLLOUT OF SECOND DOSES
The Government’s four-week delay to the ending of lockdown will be designed to buy time for the vaccine rollout to get second doses to more adults to try and protect them from the Delta variant.
Public Health England has warned that a single dose of vaccine, which used to protect well against the virus, no longer cuts it for most people.
Government data show that more than half of adults have had their second vaccine doses already but millions more still need them. A staggering eight out of 10 have had their first dose
In a report published last week it said the estimated protection from one dose of either jab has fallen from 50 per cent against the Kent variant to just 33 per cent against Delta. The reduction in protection after two doses is much smaller, with it falling from an estimated 88 per cent to 81 per cent.
MailOnline analysis of official figures last week showed all people aged 50 and above could all have had their second vaccine dose by June 17, at the current rate of immunisation, with protection kicking in a week or two later.
But the under-50s may not all have received by their final jab until September 18, fueling concerns a surge in Covid infections caused by the Indian variant may result in a spike in deaths and hospitalisations among the unvaccinated.
This assumes the rollout will continue at its current average daily pace of around 265,000 second doses a day, which would be dependent on both supply and uptake rates.

Dr Simon Clarke, a microbiologist at the University of Reading, agreed that the data suggests delaying lockdown easing by two weeks would make sense.
He said: ‘June 17 for all over-50s to have had both doses does seem realistic. And I think they are going to delay June 21 because it takes two weeks for those vaccines to kick in and over-50s are going to be the most important to get done.’
All over-50s in England could be fully protected against Covid by July 1 — nearly two weeks after ‘freedom day on June 21 — but it will take until September for all adults to have had two jabs, MailOnline analysis can reveal
DEATHS STILL FLAT – BUT QUARTER OF NEW VARIANT VICTIMS WERE FULLY VACCINATED
The number of people dying each day of coronavirus remains relatively flat – the daily average reported deaths is nine and the figure has been between eight and 10 for the past three weeks.
It briefly fell to a daily average of six for four days in mid-May but has not been lower than that at any time in the pandemic, not even last summer when the virus had been all but stamped out.
Deaths usually take between two weeks and a month to react after a spike in cases because it can take people so long to die of Covid after they test positive.
Although the success of the vaccines now means that there were will have to be significantly more cases per death compared to earlier waves of the virus, scientists still expect the number of fatalities to rise and fall along with infections – they just hope there will be fewer.
Professor Neil Ferguson said last week: ‘It’s well within the possibility that we could see another, third, wave at least comparable in terms of hospitalisations as the second wave. At least deaths, I think, certainly would be lower.’
A lingering worry, however, is the fact that vaccines won’t perfectly protect people and that ‘vaccine failure’ is inevitable in some people – most likely the old and frail.
Public Health England figures show that almost a third of the 42 Britons who have so far died from the Indian (Delta) Covid had been given two vaccine doses.
The PHE report showed that of those 42 people who died, 12 were fully vaccinated. From the remaining members of the group, 23 were unvaccinated, while seven had received their first dose more than 21 days before, suggesting they had one-dose protection.
The latest data puts the vaccine effectiveness against symptomatic disease against the Delta variant at 33 per cent after one dose. After two doses, this rises to 81 per cent. This is is lower than the Alpha variant, where the figures are 51 per cent after the first dose, and 88.4 per cent after the second.
