Reproductive number Re, Switzerland, 08.06.2020 to 21.06.2021
The graphic shows the upper and lower estimates of the reproduction number, with the Re number that is communicated in the middle for the selected time frame.
The Re number is a statistical estimate made on the basis of extensive data and statistical assumptions. The current Re number depicts the infection situation in Switzerland 10 to 13 days ago (14 to 17 days ago for the cantons). These delays are due to the time delay between infection and receiving a positive test result. An Re number that has already been published can be updated later on the basis of data delivered subsequently.
The past days’ Re numbers may fluctuate slightly. These fluctuations occur especially in small regions when the dynamics of the infection situation change and the number of cases is low.
The estimates are bounded by an upper and a lower value which represent a probability of 95 per cent.

The effective reproductive number (Re) indicates how many people an infected person infects on average under the current conditions. If the number is less than 1, there will be fewer new infections. If the number is greater than 1, the virus is spreading more intensely. In order to curb the spread of the virus, the reproductive number must be less than 1.
