Covid

With the latest XBB 1.5 sub-variant, it does seem to be yet more transmissible again and able to escape the immunity that many countries have got because of recent epidemics with BA5 or XBB or other Omicron sub-variants. So it is a concern. COVID is not going to disappear. It's going to continue to evolve. And we're going to see some people getting quite serious COVID illnesses. There are no previous waves of say, Omicron BA1, BAT or something else, that there's no immunity in the population to infection.
