This is a calculation of the number of people infected by 1 person with corona. We show the reproduction number from 2 weeks ago, because a reliable calculation of the reproduction number can be made after 14 days.
The reproduction number (R) indicates how fast the coronavirus is spreading. R shows how many people on average are infected by someone who carries the virus. With an R of about 1 the number of infections remains about the same, lower than 1 is a decrease and higher than 1 is an increase.
