Episode description
The UK has introduced new rules requiring all people arriving in the country to self-isolate for 14 days. But given the severity of the UK’s outbreak can there be many places more infectious?

The first figures are out showing how England’s Test and Trace programme is performing, but they contain a mystery we’re keen to resolve. And we play with some mathematical puzzles, courtesy of statistician Jen Rogers.
