Has Boris seen the Omicron data?

There was nothing but gloom about the Omicron variant at yesterday’s No. 10 press conference. But with reporters preoccupied with last year’s Christmas parties, no one thought to bring up a statement by Tedros Adhanom Ghebreyesus, the head of the WHO, who earlier told reporters that there is ‘some evidence that Omicron causes milder disease than Delta, but again it’s still too early to be definitive.’ 

You don’t want to make decisions before you have good evidence, but if it does turn out that Omicron is a milder disease, won’t the government’s efforts to suppress it with travel bans and restrictions be counter-productive? If Omicron makes people significantly less ill than Delta, it should be allowed to out-compete Delta.

So, what evidence do we have that Omicron may produce a less severe disease? Doctors in South Africa were surprised by the mildness of symptoms shown by some patients very soon after it was detected.
