COVID-19: Spike in Omicron cases in children could lead to another surge in adults, scientists suggest

The return to school is driving up Omicron infections in children and could lead to another surge in adults, scientists have warned. The latest results from the REACT-1 study, which is based on around 100,000 random tests across England, show that the infection rate in primary school-age children was 7.8% - and rising - during the study period of 5 to 20 January. By contrast infection rates in adults were far lower and falling, with people over 75 least likely to have COVID at 2.4%.
