Transmission of SARS-CoV-2 in a primary school setting with and without public health measures using real-world contact data: A modelling study.

Background: Stringent public health measures have been shown to influence the transmission of SARS-CoV-2 within school environments. We investigated the potential transmission of SARS-CoV-2 in a primary school setting with and without public health measures, using fine-grained physical positioning traces captured before the COVID-19 pandemic. Methods: Approximately 172.63 million position data from 98 students and six teachers from an open-plan primary school were used to predict a potential transmission of SARS-CoV-2 in primary school settings. We first estimated the daily average number of contacts of students and teachers with an infected individual during the incubation period. We then used the Reed-Frost model to estimate the probability of transmission per contact for the SARS-CoV-2 Alpha (B.1.1.7), Delta (B.1.617.2), and Omicron variant (B.1.1.529). Finally, we built a binomial distribution model to estimate the probability of onward transmission in schools with and without public health measures, including face masks and physical distancing. Results: An infectious student would have 49.1 (95% confidence interval (CI) = 46.1-52.1) contacts with their peers and 2.00 (95% CI = 1.82-2.18) contacts with teachers per day. An infectious teacher would have 47.6 (95% CI = 45.1-50.0) contacts with students and 1.70 (95% CI = 1.48-1.92) contacts with their colleague teachers per day. While the probability of onward SARS-CoV-2 transmission was relatively low for the Alpha and Delta variants, the risk increased for the Omicron variant, especially in the absence of public health measures. Onward teacher-to-student transmission (88.9%, 95% CI = 88.6%-89.1%) and teacher-to-teacher SARS-CoV-2 transmission (98.4%, 95% CI = 98.5%-98.6%) were significantly higher for the Omicron variant without public health measures in place. Conclusions: Our findings illustrate that, despite a lower frequency of close contacts, teacher-to-teacher close contacts demonstrated a higher risk of transmission per contact of SARS-CoV-2 compared to student-to-student close contacts. This was especially significant with the Omicron variant, with onward transmission more likely occurring from teacher index cases than student index cases. Public health measures (eg, face masks and physical distance) seem essential in reducing the risk of onward transmission within school environments.

Australian Educators' Perceptions and Attitudes Towards a Trauma-Responsive School-Wide Approach.

Staff perceptions and attitudes regarding the introduction of the Reframing Learning and Teaching Environments (ReLATE) trauma-responsive school-wide approach were investigated in three Catholic primary schools in Victoria, Australia. School leaders, teachers, and support staff were interviewed regarding their experiences of the approach either individually or in focus groups. Educator attitudes towards trauma-responsive education was evaluated using the ARTIC-ED Scale, prior to and after participating in the six-month intervention. Qualitative data were interpreted using ecological analysis of the themes arising guided by the trauma informed principles and frameworks of the Substance Abuse and Mental Health Services Administration (SAMHSA) and the Trauma Learning Policy Initiative (TLPI). Findings indicated significant shifts towards trauma-responsive practice following the introduction of ReLATE. Strong themes emerged relating to the influence of improved trauma knowledge on perceptions of student behavior, consequent reported adaptations to behavior management practices, strengthened sense of trust and respect in the school climate, the centrality of leadership to effect change, and importance of school-fit to program uptake. Strengths and limitations of ReLATE are considered, along with implications for teacher professional learning, the role of leadership in effecting change and significance of perceived school-fit and collaboration.
