These waves have disproportionately affected primary and secondary schools, and many of the new sufferers are children. Sadly, far from any subsidence in new long Covid cases, the big, ongoing caseloads of the Delta, Omicron and BA.2 waves have brought a large cohort of new sufferers.įrom published data, the chances of long Covid in those who are vaccinated but suffer breakthrough infections may be halved, but when you apply this to the huge waves we’ve experienced – 3.5 million people infected at a given time – each 3.5 million cases becomes another 175,000 people with long Covid. We thought that the number of long Covid cases developing might be lower when most cases were breakthrough cases in the vaccinated, or infections in vaccinated or partially vaccinated children.

Even though it was clear from the outset that the risk of long Covid was not correlated simply with the severity of infection, there was every reason to hope that with the large-scale rollout of effective vaccines, and more recent waves of infection dominated by a somewhat less severe variant, there would be few additions to the sufferers joining long Covid support groups. Many of the most severe and enduring “long-haulers” derive from the first UK infection wave just before the initial lockdown in March 2020.
