It’s not the news we wanted to end 2022, but a potentially dangerous new Covid-19 variant has started to spread in the UK. It’s called XBB.1.5 and has gone from 0% to around 2 or 3% of all infections in the UK in less than a month. This is one of the fastest rates of growth of any new variant.
XBB.1.5 is extremely immune-evasive, meaning it can get around immunity you may have from vaccination or having had Covid before, even recently. In the US, where XBB.1.5 has been circulating for a few weeks, it is associated with a much higher level of deaths and hospital admissions than other Omicron variants. This strongly suggests that XBB.1.5 is more likely to lead to very severe illness than other Omicron variants.[1]
