I’m slightly surprised to be writing this post as to my mind the answer is obvious – of course the U.K. will face a winter Covid surge. It’s winter. That’s what happens in winter; the dominant respiratory virus surges and, most years, taxes the capacity of the health service. The only question is how big it will be – unusually large like 2020-21, or unusually small like 2019-2020 before Covid hit? It’s worth remembering that more people died in England and Wales per head of population in 2008 (once adjusted for age etc.) and every year prior to it than died in 2020 or 2021, many of them succumbing during the winter flu season, as the chart below from the Institute and Faculty of Actuaries shows. In other words, there’s a winter surge in deaths-by-virus every year, and I see no reason why 2021-22 will be any different.
As I see it, the only realistic way there would not be a Covid surge on some scale is if another influenza-like virus takes over, which seems unlikely right now as flu is almost nowhere to be seen.
Nonetheless, I am writing this post, and that’s because some people seem to think that this year it’s not going to happen. Dr Sebastian Rushworth argues that places hit hard already, such as Sweden, New York and Lombardy, have developed enough immunity to avoid “another big wave” altogether. Andrew Lilico in the Telegraph maintains that owing to “infection saturation” and vaccine third doses, “for us, the Covid crisis is over”. Even the usual doom-mongers at SAGE are predicting a decline in hospitalisations and deaths in December, according to new modelling released on Friday. A decline in flu-like hospitalisations and deaths in December? Whoever heard of such a thing?
I freely admit that the winter surge may, because of acquired immunity, be relatively small in places like the U.K. which have already faced widespread exposure. Perhaps that’s all that Sebastian Rushworth and Andrew Lilico mean, and in which case our positions are not so far apart. But will it really be a non-event, as SAGE at least appears to be implying, so that Covid deaths decline during the winter and don’t put any further pressure on the health service?
