Can somebody link to the advice to avoid crowds if over 60 or immunocompromised?

Frustrated I cant find it - I think it was a Dr Margaret Something? Mention of avoiding crowds, trains etc if over 60 or if you have underlying conditions?

There are about 60 pages of recent thread and can't find it so hoping someone has a link.

Doc was with the WHO if I remember right..

Not sure how to link Twitter posts but there's a tweet by Tedros Adhanom Ghebreyesus, WHO Director, on 29 February advising those over 60 and those with underlying health conditions.

It was on the twitter of the director general of WHO mobile.twitter.com/DrTedros/status/1233695157888987137 on 29th Feb.

Thank you.
