On Thursday, the UK’s four devolved authorities reported 740 deaths in England, 80 in Scotland, 32 in Wales and 18 in Northern Ireland – totalling nine more deaths than the central figure. Here’s a quick primer on what all the different numbers mean and how to understand them.

Meanwhile, as of 9am on Thursday, 103,093 people in the UK have tested positive for the disease, including 4,618 in 24 hours.
