[{"arm_notes": "", "treatment_id": null, "treatment_name": "Schools and colleges are stratified by size (<500 of =500 students on register); type (maintained; independent; residential; special provision); presence of a sixth form; and proportion of students eligible for free school meals (=17% or =17%); then randomised within strata in blocks of 2. Consenting first-order contacts of a COVID-positive index case will receive daily contact testing for 7 days from the point of being notified they are a close contact. This will consist of a daily lateral flow device (LFD) test*. Those that receive a negative LFD result can attend school for that day; but other than travelling to and from school will be instructed to continue to self-isolate outside the school setting. Those that receive a positive LFD result should not attend school and will be instructed to self-isolate for 10 days according to national guidelines. The contacts of all first-order contacts (i.e. \u2018second-order contacts\u2019) will be identified to allow the determination of the secondary attack rate. The control group will test individuals twice a week; followed by isolation of any positive cases and their contacts. The intervention group will follow the same twice-weekly testing for individuals; but any contacts of positive cases will be asked to test daily in school/college for 7 consecutive days as an alternative to self-isolation; and as long as they continue to test negative; they will be able to carry on going to school/college. The trial is voluntary. Participants who are part of active case finding can choose not to participate in DCT or drop out of DCT at any point.", "treatment_type": "TODO", "pharmacological_treatment": "TODO"}]
