About the research

With the COVID Radar app the LUMC collections data about your health and behaviour. With this data we want to get a better overview of the spread of the coronavirus (COVID-19).

The importance of participation
In the Netherlands, there is so far limited testing whether people have the coronavirus or not. A person is only tested if he / she has symptoms, is hospitalized, belongs to a vulnerable target group, or works in the healthcare sector himself. As a result, we do not yet know exactly how many people in the Netherlands are infected with the virus. By collecting data on complaints from as many people in the Netherlands as possible, we can investigate how many people have (had) the corona virus and where they reside in the Netherlands. With this data we try to predict who is at great risk and who will be less and what the expected care demand will be: how many corona patients do we expect where and when? Your contribution to this research is very important to arrive at population-oriented advice and to predict the need for care. Do you have any questions about the app? Mail to
