Omicron is much more infectious than previous variants, but so far seems to be less severe. “The numbers of cases are just so high, really everywhere,” said Tara Kirk Sell, a senior scholar at the Johns Hopkins Center for Health Security. “And if they’re not high yet, they will be high. It’s incredibly transmissible. As a result, more children are being hospitalized with COVID-19. However, experts believe the increase correlates with the skyrocketing number of people getting infected, not the severity of disease the variant causes in kids.
