A spike in infections every three months seems to be the pattern, but the UK has the power to beat this if we act wisely
As we move into summer, more than two years since the outbreak of the Covid-19 pandemic, the words “new wave” are probably the last thing anyone wants to hear. Yet it is true that recent UK data (as well as data from Florida and other places) indicates that sublineages of the Omicron variant, BA.4 and BA.5, are kicking off a new wave of cases. With the pandemic no longer dominating the news in the way it once did, it’s worth taking stock of where we are and what needs to be done.
After all, these variations on Omicron are not more severe, but they do have the capacity to reinfect people, even those who have had a previous version of Omicron. This is further evidence that reaching “herd immunity” (where enough people are vaccinated or infected to stop further circulation) against Covid-19 is probably impossible.
