COVID-19 circumstances, hospitalisations and deaths have been rising within the UK, pressurising a well being service that’s already working arduous to deal with the backlog of non-COVID sufferers which have accrued since March 2020.
Whereas some modellers counsel that circumstances have peaked and are actually set to fall, the general variety of new infections isn’t the one development to concentrate to. Extra circumstances in older age teams and rising hospitalisations are causes for concern, with each probably pushed by two different worrying developments: waning immunity and the vaccine booster programme rolling out too slowly.
The federal government is taking discover, holding a COVID press convention in response to the latest rise in circumstances, however is but to vary course. Its technique for controlling COVID at present nonetheless relies upon primarily on vaccination.
It’s resisting requires the stricter “plan B” management measures, outlined in its COVID winter plan, to be carried out now. These measures embrace, in sure conditions, introducing vaccine certificates and reintroducing obligatory face coverings, along with suggesting that folks do business from home.
However wanting intently on the present knowledge, the plan B measures – and even different, simpler steps – appear inevitable within the coming weeks and months.
Susceptible persons are getting COVID
Within the second half of October, reported new circumstances of COVID surpassed 50,000 a day for the primary time since July. Nevertheless, the present scenario is considerably extra regarding than in July. Again then, circumstances had been solely excessive within the younger. Now circumstances have risen considerably within the older half of the inhabitants.
The case charge among the many over-60s is the very best it’s been since late January. We all know that is particularly vital, as a result of regardless of making up lower than 1 / 4 of the inhabitants, the over-60s make up greater than half of all COVID hospital admissions. Rising circumstances on this age group disproportionately results in individuals getting severely unwell with COVID and hospitals coming below strain.

The variety of COVID sufferers in hospital in England reached 6,801 on October 25, the very best determine since mid-March. It’s price noting {that a} 12 months in the past in October 2020, the federal government known as a nationwide lockdown when hospital occupancy reached roughly 10,000. On the present trajectory, it appears possible we’ll attain this milestone ultimately this winter. If we’re to keep away from it, we don’t simply want circumstances to come back down, however circumstances within the older age teams to fall specifically.

Boosters, passports – and extra?
Because of vaccination, we gained’t see hospital occupancy shoot up as quickly because it did in October 2020. So even when we do attain 10,000 COVID sufferers in hospital, a lockdown is unlikely. Admissions growing extra slowly means there’s far much less threat of the NHS abruptly turning into overwhelmed, which is what previously necessitated drastic lockdown measures being launched. Nevertheless, it’s possible we’ll see pressure on the NHS rise to a stage that justifies extra motion.
Pressures on the NHS are already very critical, particularly in emergency care, the place A&E ready instances are the worst since data started. Round 25% of individuals attending A&E aren’t seen throughout the goal time of 4 hours, and persons are routinely ready 45 minutes for an emergency ambulance. This strain isn’t primarily on account of COVID, however the return of regular ranges of attendance at A&E, along with elevated severity of sufferers, staffing points and an infection management measures making life more durable in A&E departments.
The federal government due to this fact is correct to be pursuing a coverage of booster vaccinations for over-50s. Older teams within the inhabitants are extremely vaccinated – over 90% of 60- to 69-year-olds are double vaccinated and over 95% of over-70s – however the truth that we’re seeing elevated circumstances and hospitalisations on this older cohort suggests vaccine-based immunity is waning. Rising analysis additionally suggests that is the case (although its findings nonetheless must be formally reviewed by different scientists).
Immediate deployment of those further vaccines ought to cut back circumstances and hospitalisations considerably. Information launched by Pfizer – whose vaccine is the booster of selection within the UK – suggests {that a} third dose restores immunity to extremely protecting ranges (although these findings are additionally nonetheless awaiting evaluate).
The issue is that the booster programme seems to be not on time in getting third doses to individuals as they turn into eligible six months after their second. We additionally don’t know if the take-up of boosters shall be as excessive as for the preliminary two doses. If it’s not, many individuals might find yourself susceptible to hospitalisation and loss of life from COVID this winter.
The well being secretary, Sajid Javid, has conceded that the federal government’s plan B could also be crucial if pressures on the NHS turn into unsustainable, however the elements of this plan appear fairly weak in comparison with restrictions that had been used earlier this 12 months. Would these measures carry down transmission and cut back circumstances – and due to this fact hospitalisations – in older, extra susceptible age teams? Presumably not. The Cupboard Workplace’s COVID-19 Taskforce estimates that the affect of those measures on transmission may solely be “reasonable”.
Some consultants have pointed to much less invasive measures that is also launched. Bettering the focusing on of testing by revising the listing of signs that permit individuals to ebook a PCR check, and even dropping large-scale PCR testing in favour of cheaper fast lateral circulation checks, may make discovering and isolating circumstances faster. Nevertheless, such modifications stay unlikely for now. This implies plan B, if carried out, might battle to attain its objectives of relieving strain on the NHS.
Nonetheless, additional measures to restrict the unfold of the virus, comparable to these in plan B, appear inevitable except progress may be made on decreasing circumstances in older age teams. If circumstances amongst these teams stay excessive, extra drastic restrictions – comparable to imposing social distancing in hospitality venues sooner or later this winter – stay a powerful risk.
