Universities are being told to stagger the return home of England’s 1.2 million students in the week after the national lockdown ends. The aim is to avoid a sudden exodus that could spread infection. Universities will be expected to move almost all teaching online by 9 December. Before travelling, as many students as possible will be offered Covid tests and anyone who’s positive will be required to self-isolate on campus for 10 days. They’ll still be able to get home for Christmas once that period is up. The Scottish government is expected to outline similar plans later.
