CME Credits: 1.00
Released: 2022-05-23
The New York City public school system is the largest in the US, with more than 1600 schools and more than 1 million enrolled students. For the 2021-2022 school year, COVID-19 safety measures included mandatory vaccination for all adults; daily health screening; universal face coverings; improved indoor air quality using windows, portable air purifiers, and/or central air filtration; testing of unvaccinated persons; and quarantine for unvaccinated contacts. There was substantial concern that the Delta variant, which caused a surge in July to August 2021, would disrupt the school year. To assess the effectiveness of COVID-19 prevention measures against the Delta variant, we measured the secondary attack rate for COVID-19 cases diagnosed in students, teachers, and staff from October 10 to December 5, 2021, and analyzed the likely direction of transmission for secondary cases, stratified by vaccination status.
