No vaccines for young children, but schools can reopen safely in the fall, a study shows
LA TimesStudents wear masks and sit at socially distanced desks at a school in Ramona, Calif. Over the course of 2,000 runs of their model elementary school with a relaxed approach to masking, social distancing and isolation, a single infected child was likely to spread the coronavirus to an average of 1.7 other children over 30 days, researchers found. With students on campus five days a week and relaxed social distancing and masking measures in place, an outbreak seeded by a single high school student could touch off 23 to 75 additional infections among fellow students, employees or classmates’ families over the course of a month. They emerged from a detailed “agent-based” computer model, in which virtual individuals in a population of students, school employees and students’ families interact under defined rules that dictate the behavior and infectiousness of each. The report’s findings “reinforce the importance of continued COVID-19 prevention measures among adolescents, including vaccination and correct and consistent wearing of masks,” the authors wrote.
