Eligibility

Inclusion criteria

Inclusion criteria: Testing trials: One invitation letter per household was sent to all residents of Dronten and Bunschoten. In the invitation letter, all residents aged 12 and above in Dronten, and aged 6 and above in Bunschoten were invited to partake in the community-wide testing pilot. Self-Isolation support trials: All residents of Dronten and Bunschoten with a positive test result for covid-19 received care as usual during the six week pilot period, and were invited to partake in the trial. In Bunschoten, close patient contacts at risk of Covid-19, were also invited to partake. Intervention materials developed for the trial only offered to patients aged 16 and above due to legal requirements. In case of patients under the age of 16, intervention materials were offered to the household. Intervention materials were, under those circumstances, also addressed ‘parent(s) of’ the minor in the household. Only participants with insufficient written and spoken knowledge of the Dutch language were unable to participate in the trials.

Exclusion criteria

Exclusion criteria: Testing trials: No exclusion applied to participation, but data was only shared for residents aged 12 and above in Bunschoten. This was because a different set of methods was used to test participants aged 6-12 for Covid-19. We will only exclude a subject from which the district the subject is living or the condition the subject is assigned to is missing. If the condition a subject belongs to, or the district a subject lives in is missing, this subject will be excluded from the analysis. Self-Isolation support trials: No exclusions were applied to receive self-isolation care as usual.
