The UK’s R-number, which represents the rate of transmission, now sits at between 1.1 and 1.2.

The R number represents the average number of people an infected person will pass the disease on to.

If R is below one, then the number of people contracting the disease will fall; if it is above one, the number will grow.

The government has previously said that the R number is one of the most important factors in making policy decisions.
