From November 2022 to May 2023, students and staff self-collected nasal swabs and reported respiratory symptoms. The researchers found that 85.5% of participants had at least one virus detected and 80.4% had at least one ARI episode. Per 100 enrollment days, adjusted virus detection rates were highest in pre-K and elementary, followed by middle, high school, and staff (1.46, 1.51, 1.19, 0.90, and 0.87, respectively). Per 100 enrollment days, the adjusted ARI rates were 1.66, 1.19, 1.17, 0.76, and 1.45 for pre-K, elementary, middle, high school, and staff, respectively. More information: Jennifer L.
