LONDON : London was put on a coronavirus watchlist on Friday while stricter lockdown restrictions were imposed in several other British cities as the R number, or the rate at which the infection is spreading, went further up beyond the mark of one.The R number, which indicates the average number of people each person with coronavirus goes on to infect, needs to remain below 1.0 to keep the pandemic under control.
That number is now between 1.2 and 1.5, which means that on average every 10 people infected will infect between 12 and 15 others.London Councils, which represents the bulk of the boroughs in the UK capital, said that while no additional measures are being deployed for the UK capital yet, testing capacity is being boosted."London.
