There's been a lot of news recently about reopened travel routes, including the opening of the US-Mexico border and the resumption of transatlantic flights. One person not looking to take advantage of that is the World Health Organization's Dr David Nabarro. As part of his Sky News interview in the UK this morning he had this to say about travel:

Why am I not travelling very much? Because I don't want to get Covid - I'm in the wrong age group and I've got other adverse factors as well.

So, I'm trying to say to everybody travel if you must - and there are often essential emotional reasons as well as essential economic and another reasons - but try not to travel if you don't have to.
