Disturbing trend: Delta spreading among children: The world is facing yet another big challenge. The Delta variant is dashing hopes for a return-to-normal school year in the US. Children are filling hospital beds instead of classrooms in record numbers across the US. The surging virus is spreading anxiety, turmoil and infighting among parents, administrators and politicians. The stats are staggering. More than 400 American children have died of COVID-19 since the start of the pandemic. And almost 2,000 kids are now in US hospitals, many of them in ICU, some of them under the age of 4. The disturbing fact is adults who have not gotten their shots are contributing to the surge. In Australia, 45% of all active cases in Melbourne are in children and teenagers. Taking heed of US trends, several Indian states are building facilities with more paediatric beds, due to concern that children returning to school without being vaccinated will be among the most vulnerable during a third wave. The onus is on us. We all need to protect our children, [COMMENT BY: Stephen N.R., Senior Associate Editor]
