RENBP and infection: For example, for the most effective surveillance intervention (routine RT-PCR testing + 2-round Ag-RDT screening on days 1 and 5; intervention #23 in Supplementary table S2), apparent efficiency of screening ranged from A = 3.3–3.6 infections detected/1000 Ag-RDT tests if targeting patients, A = 6.2–6.3 infections detected/1000 Ag-RDT tests if targeting staff, and A = 5.1–5.2 infections detected/1000 Ag-RDT tests if targeting both patients and staff.
