The coronavirus has the Netherlands in its grips. To gain insight into how people view the imposed coronavirus measures in the Netherlands, their motivation in adhering to the measures, and what the impact is on their daily lives, RIVM National Institute for Public Health and the Environment and GGD GHOR (the Netherlands Municipal Public Health Services and Medical Assistance in Accidents and Disasters) are conducting a large-scale study on this topic. The study explores human behaviour, what people think of the government’s behavioural measures, and how they are doing physically, mentally and socially in these corona times.
