Reproduction number
Number of people infected by one infectious person. The reproduction number is a calculation and is updated every Tuesday and Friday. The reproduction number is two weeks old, because a reliable calculation of the reproduction number can be made after 14 days.
The reproduction number shows how fast the virus is spreading. The number shows how many people are on average infected by someone who is infected with the corona virus. The number of transmissions remains more or less constant when the reproduction number is 1, declines when it is less than 1 and increases when the number is above 1.
