Defying Delta: Back to school goes better than feared

School for children in many nations has been underway for more than a month and fears the Delta coronavirus variant would derail in-person learning have largely proven unfounded. In a dozen countries with high vaccination rates in Asia, Europe and the United States, case rates that surged in August have mostly fallen back, according to local data and officials. The jury is out on how much this is due to seasonal factors amid a global decline in cases, and how much it is linked to vaccinations and other preventative measures. Public health experts say they will continue to watch for signs of an increase in cases as winter approaches.
