Dr David Nabarro, one of the World Health Organization’s (WHO) special envoys on Covid-19, urged people to be “careful” when students in the UK return to university after Christmas to prevent a spike in Covid-19 cases.

Asked about students returning to UK universities in January, and if there was an argument for keeping students at home for longer, Dr Nabarro told Sky News:

We did see that there was quite a big increase in cases in Europe in October and November. We think that was to do with movements that took place in September, including students coming to university.

So if there’s going to be a big return in January, all I’m going to say is, everybody be careful. Because that’s when the virus can really move around quickly.
