As we head into one other winter, Covid numbers have been ticking up. However how fearful ought to we be about Covid nowadays – can we deal with it like a chilly, or have we change into blase about an sickness that would nonetheless pose a menace to aged and clinically susceptible folks?
How does Covid evaluate to a chilly or seasonal flu?
Seasonal flu has been a benchmark for Covid since early within the pandemic, and for a while Covid has had a decrease mortality fee. Final winter Covid prompted fewer deaths than flu – 10,000 versus simply over 14,000, in accordance with the UK Well being Safety Company. Nevertheless, Covid stays a extra severe sickness than a typical chilly, with one research displaying that for individuals who change into unwell sufficient to be hospitalised, Covid nonetheless has the next threat of demise. “The issue is lots of people say they’ve acquired flu once they haven’t,” stated Prof Paul Hunter, an professional in infectious ailments on the College of East Anglia. “Flu just isn’t nothing – it’s a nasty an infection that sometimes kills 20,000 folks in a winter.”
When it comes to the general influence on the well being service, Covid continues to be probably so as to add to pressures this winter. “We’re not in 2020 or 2021 and that’s factor,” stated Prof Christina Pagel, of College School London. “However we’re additionally not in 2019. We’ve nonetheless acquired a brand new illness that’s killing 1000’s of individuals every year and we’ve acquired lengthy Covid.”
Can we nonetheless maintain observe of how many individuals are contaminated with Covid ?
For the reason that Workplace for Nationwide Statistics an infection survey wrapped up in March, it has been exhausting to understand how many individuals are contaminated within the UK. Nevertheless, official UKHSA figures, which present infections in hospital, point out whether or not an infection charges are rising or falling. This week’s figures counsel that infections, which had been steadily growing since August, at the moment are happening once more throughout all age teams.
Has Covid change into a seasonal sickness?
Final 12 months, as new variants arrived in fast succession, there have been a number of massive waves of an infection, together with throughout the summer season months. This hasn’t been the case in 2023, which some say signifies Covid is settling right into a seasonal sample, with indoor mixing and decrease temperatures permitting the virus to unfold extra readily in winter. “In pandemics with comparatively brief durations of immunity you all the time get a collection of progressively dampening waves as you progress in the direction of the endemic equilibrium,” Hunter stated. “Seasonality will finally begin taking part in a job. The opposite human coronaviruses typically comply with a seasonal sample the place they peak between November and February.”
Is the opportunity of new variants nonetheless a menace?
The so-called Pirola variant (official title BA.2.86) prompted unease after being detected in Denmark in July and steadily spreading to different nations. The pressure has a lot of mutations, elevating the chance that it might evade current immunity or might have modified in a manner that makes it extra virulent or extra infectious. This has not transpired to be the case with this explicit pressure. “There was a variety of hype however that’s been a little bit of a humid squib,” stated Hunter. “It’s nonetheless progressively growing as a proportion of all infections however not dramatically so.”
The prospect of a brand new variant inflicting a dramatic resurgence could also be receding however scientists stay alert to this risk and proceed to observe the emergence of recent strains – though England has dropped its wastewater surveillance programme. “It’s a complicated time,” stated Prof Danny Altmann, an immunologist at Imperial School London. “If you happen to stay in my world, the place you’re nonetheless taking a look at sequences of viruses, we’ve nonetheless acquired our guard up. However no person has the abdomen for that battle any extra.”

It’s nonetheless advisable to remain at dwelling and keep away from social contact if in case you have Covid signs. Nevertheless, views differ on testing. Shropshire group NHS belief apologised final week after issuing an e mail warning workers to not check for Covid as a result of it might end in them “having to stay at dwelling for longer than their signs persist”.

We now have a staffing disaster within the NHS however that is such a nasty method to cope with it. If you happen to’re giving Covid to older folks and people with different well being situations, they find yourself in hospital for longer, so that you’re making mattress points worse and you find yourself with extra folks off work.”
Pagel says testing can nonetheless be helpful as a result of returning to train too shortly after Covid can result in a slower restoration – so if you realize you’ve had Covid you possibly can take it straightforward. And if you happen to develop lengthy Covid, realizing that you just’ve had an an infection will be helpful for prognosis.

For these exterior the eligible teams, it’s not attainable to pay privately for a Covid booster injection at a pharmacy, however this might change subsequent 12 months. There was little demand for personal vaccinations till just lately as a result of beforehand all over-50s had been eligible for NHS vaccination. Nevertheless, a number of corporations, together with Moderna, have just lately submitted purposes to the Medicines and Healthcare merchandise Regulatory Company to replace their licences to permit them to provide vaccines in particular person pre-filled syringes, which might make it simpler for pharmacies to supply one-off doses.
Is lengthy Covid nonetheless an issue?
As immunity builds up within the inhabitants, the probabilities of Covid turning into lengthy Covid has diminished considerably, though the full quantity has change into more durable to trace. In March, when the ONS recorded its final survey, an estimated 1.9 million folks within the UK (2.9% of the inhabitants) stated they believed that they had lengthy Covid (signs persevering with for greater than 4 weeks), with 381,000 of those (20%) reporting that their capability to undertake their day-to-day actions had been “restricted rather a lot”. Final month, the ONS reported that report numbers within the UK – 2.5 million – weren’t working attributable to long-term unwell well being, with proof that lengthy Covid might be having an influence.
