Abstract Systematic SARS-CoV-2 testing is a valuable tool for infection control and surveillance. However, broad application of high sensitive RT-qPCR in children often hampered due to unpleasant sample collection, limited capacities costs. Here, we developed high-throughput approach (‘Lolli-Method’) detection children, combining non-invasive collection with an RT-qPCR-pool strategy. infections were diagnosed sensitivities 100% 93.9% when viral loads >10 6 copies/ml 3 corresponding...
