When does shielding begin

I think it depends very much upon what course of treatment you have had (or are having).  I only had surgery (late Jan) and was advised just before lock down at a review meeting that I had no elevated risk from Covid-19.  I was concerned that with throat surgery I was more susceptible, but apparently not. Others, especially if chemo is involved, may be advised differently. 

Thank you. I will be starting a course of chemo and RT, no surgery. I’m in hospital next week so I guess I’ll know then. Just trying to get ahead on some things.

You’ll need shielding from now. 
It means staying at home.

You should be contacted by your council and you’ll get preferential supermarket delivery slots or food parcels if you can’t manage yourself. 

Oh. No one has told me anything. I’ve just come back from my five mile exercise! Thank you. I’ll speak to the nurse on Monday when I go in for my Covid test.

thanks
