Abstract

Since the beginning of the pandemic, more than 13.9 million children under 18 years of age have been infected with SARS-CoV-2. COVID-19 has resulted in devastating loss of human life and presents an unparalleled challenge for public health as it is currently ranked among the top ten causes of death for children 5-11 years of age. School-aged children are not only susceptible to SARS-CoV-2, but can play a role in transmitting the virus through educational settings. While many wastewater-based surveillance efforts have been used to study the transmission of SARS-CoV-2 throughout college dormitories, there have been few studies employing wastewater epidemiology to analyze COVID prevalence in K-12 school sites while investigating school related factors and community factors that can influence the transmission and detection of SARS-CoV-2 in a school. Three main objectives of this study are to 1). Collect and analyze weekly wastewater samples from selected Atlanta Public Schools and compare the wastewater results from Atlanta Public schools to the weekly reported COVID-19 cases among students (August 2021-March 2022) 2). Understand why specific Atlanta Public Schools have higher SARS-CoV-2 detection rates in wastewater as compared to others, and 3). Investigate each school’s catchment area and socio-demographic characteristics to identify factors that may be linked to positive wastewater outcome and COVID-19 cases in Atlanta Public Schools. Findings from the study analyses revealed that overall, 41% of wastewater samples detected the presence of SARS-CoV-2 in schools and that elementary schools were found to have the highest overall proportion of SARS-CoV-2 detection in wastewater (52%). Concordance between positive wastewater results and reported COVID-19 cases in schools shared a temporal trend consistent with the COVID-19 Omicron surge in Fulton County. Voluntary self-reporting of COVID-19 cases were likely an underestimate. Furthermore, results indicated that COVID-19 self-reported cases, staff vaccination rate, student vaccination rate, school group, and school neighborhood factors such as neighborhood population below poverty, and city council district location shared trends with positive wastewater outcomes in Atlanta Public Schools. Overall poverty rates amongst school neighborhoods were very high (24.4% to 34.9%).
