Experts: 3-foot rule in schools problematic in light of COVID variants

The Centers for Disease Control and Prevention (CDC) issued updated guidance on school reopening, saying that 3 feet, not 6 feet, of physical distancing between students was sufficient in most elementary schools—regardless of the level of community spread of COVID-19. At the same time that CDC officials were updating school policy, they were also warning that B117, a variant strain 50% more transmissible than the wild-type virus, would likely become the dominant strain in the United States by April. In some states, such as Florida and California, the variant, which was first detected in the United Kingdom, already accounts for 25% of cases.
