Typical Daily Wail reporting!
All that the Director-General of the WHO said was " . . . if you are over 60 years old, or if you have an underlying condition like cardiovascular disease, a respiratory condition or diabetes, you have a higher risk of developing severe disease. You may wish to take extra precautions to avoid crowded areas, or places where you might interact with people who are sick".

That's basic common sense. Older people often have weaker immune systems than younger ones, so it's sensible for them to avoid crowded areas in general (especially when there's any form of bug going around).
However 'avoiding crowded areas' is NOT the same as telling people not to go shopping in supermarkets, etc (as the Daily Wail seems to imply). As I'm about to start on a course of chemotherapy, there will periods in the next few months when my immune system will be almost totally switched off. The nurse who was briefing me on the implications of it told me that I should "avoid crowded places". When I asked if that meant I should effectively become a hermit during the relevant periods, she said "Definitely not! Try to avoid getting into crowded lifts and going to other places where you're squeezed in against other people but you can still go shopping and you can still go to the pub. Get out and enjoy yourself!"
