Why highlight the very small, early study with Half of the kids who contract Covid19 suffer from "long covid"? The next paragraph in your link gives 14.5%: The UK Office for National Statistics's latest report estimates that 12.9 per cent of UK children aged 2 to 11, and 14.5 per cent of children aged 12 to 16, still have symptoms five weeks after their first infection. Almost 500,000 UK children have tested positive for covid-19 since March 2020. Most medical bodies say it normally takes a few days or weeks to recover from covid-19, and that most will make a full recovery within 12 weeks.
