To those asking, Boris briefly mentioned in his speech about self isolating for the over 70's, pregnant women and vulnerable.
The Witty bloke then went further into that and gave a long winded but still lacking in much detail explanation.
So what i got from it was, if you are over 70 healthy or unhealthy you self isolate. If you are in the last 12 weeks of your pregnancy you self isolate, he explained this was because they were still in the early stages of understanding the virus and wanted to err on the side of caution.
He also said that vulnerable people will be asked to self isolate. These are people who receive the flu jab for medical conditions. He listed kidney disease and possibly heart/liver disease but made it sound like there were others.
He went on to say that there would also be a very small group of other medically vulnerable people asked to isolate. Those would be people who had Leukaemia etc
He did say they would put up a list shortly, a few hours. But nothing has come to light.
I would assume if you are in those categories and have school aged children they will need to be taken out of school to isolate alongside you. Otherwise the isolation would be pointless.
The video of the press conference is on youtube for anyone who wants to listen to it with their own ears.
