Indicator summary

Cases, deaths and testing

Since week 38 of 2020, the number of tests reported is corrected for underreporting from virological laboratories. The estimated number of tests is obtained by multiplying the weekly total number of tests reported from virological laboratories by the weekly ratio of COVID-19 notifications by Public Health Services to positive tests reported from virological laboratories. From March 31st 2021 until April 11th 2022, a positive self-test result needed to be confirmed at the Public Health Services’ system (PHS, in Dutch: GGD). From April 11th 2022 this is no longer required. Therefore, the number of people tested at the PHS as a result of a positive self-test result will decrease. Due to the changed composition in the group of people who have themselves tested at the PHS, the overall positive rate will also be lower.
