CONTROL-2: Evaluation of CONTact Reducing Government Measures

During the COVID-19 pandemic, many measures have been introduced to reduce the number of people's contacts and prevent the spread of SARS-CoV-2. However, the effectiveness of these measures has not been sufficiently evaluated. We do know that they have had a negative impact on psychosocial health and the economy. That is why we want to investigate which measures have been most effective in reducing the number of contacts, and are therefore most suitable for use in the next outbreak. For the CONTROL project, we (9 GGD regions and the RIVM) collaborated and used SARS-CoV-2 test data and source and contact investigation (BCO) data to investigate the effectiveness of the BCO. We will now use the same data to investigate to what extent the number of contacts reported during contact research by people who tested positive was influenced by the nature and severity of measures introduced by the government.
