Most children in the United States have returned to school for the year as districts aim to bring kids back to a setting that resembles the pre-pandemic normal.
Masks are now optional in most classrooms and, last month, the Centers for Disease and Prevention said it was no longer recommending schools use test-to-stay, which allowed students who were close contacts of those who tested positive for COVID-19 to continue to attend in-person classes if they remained asymptomatic and continued to test negative.
