The Coronavirus Surveillance Ordinance (CorSurV) has been in force since January 19, initially until October 31, 2021. In order to get a better overview of the variants of the coronavirus circulating in Germany, laboratories are to increasingly carry out full genome sequencing. The maximum possible number of whole genome sequencing per laboratory depends on the nationwide number of new infections in the previous calendar week. If this number exceeds 70,000, up to five percent of the samples tested positive can be sequenced. With a lower number of new infections, the limit increases to up to ten percent.
