Children attend a class on the first day of partial reopening of schools in Noida, a suburb of New Delhi, India, Wednesday, Sept. 1, 2021. Many students in India will be able to step inside a classroom for the first time in nearly 18 months from Wednesday, as authorities have given the green light to partially reopen schools despite apprehension from some parents and signs that coronavirus infections are picking up again. Schools and colleges in least six states will reopen in a gradual manner with health measures in place throughout September. In New Delhi, all staff must be vaccinated and class sizes will be capped at 50% with staggered seating and sanitized desks. (AP Photo/Altaf Qadri)
