Introduction

During the COVID19 pandemic, school districts have prepared strategies for safely reopening during the fall semester of 2020, while taking into account the potential impact of in-person encounters on students, staff, families, and public health. Nonpharmaceutical interventions, such as school and workplace closures, have been shown to have potential benefits in slowing infection spread and reducing severe health outcomes, but they have also been shown to have negative effects on the economy, unemployment, mobility, mental health, education, and caregiving, among other things. School closures around the country in the spring of 2020 had a negative influence on kids' education as well as social and economic ramifications, such as increased childcare duties for working parents. Furthermore, additional childcare obligations may contribute to greater worker absenteeism in the healthcare industry, further stressing an already overburdened system. Agent-based models reflect complex interactions and processes among subpopulations, including interventions, adaptive behaviors, and environmental impacts. They're especially useful for forecasting the development of emerging infectious illnesses since they combine disease dynamics, pharmaceutical and non-pharmaceutical therapies, and social behaviors, potentially leading to a better understanding of disease propagation and subsequent responses [1]. We used an agent-based simulation model to predict public health outcomes (such as the number of community-wide illnesses, hospitalizations, and deaths) in several school reopening scenarios in this study. Different in-person vs online participation choices and interventions, such as symptombased self-isolation and universal masking in schools, were evaluated in school reopening scenarios.

In the state of Georgia, we analyzed school reopening scenarios for the fall semester of 2020. COVID19 infections were on the rise during the time, owing to societal upheaval and greater mobility. Vaccines were also few, and data on levels of compliance with social distancing measures was inconsistent. While we base our research on the fall of 2020, the methodologies and findings can be used to future pandemic circumstances where cases are on the rise and information is scarce. If a major version of the SARS-CoV-2 virus appears and severely lowers the efficiency of existing vaccinations, the findings of our study will be useful [2]. The goal of this research is to quantify the public health outcomes (deaths, hospitalizations, and infections) of various school reopening scenarios in order to assess their impact on pandemic spread in order to provide much-needed information to school system decision-makers in the event of a pandemic.

The findings were achieved by adopting and using an agentbased simulation model to forecast COVID19's regional and temporal expansion. A computational model that simulates a number of autonomous "agents," each of which represents an individual in the population, and the model mimics the dynamics and outcomes of a real system under particular assumptions, is known as an agent-based simulation model [3]. Children (years 0-9), teens (ages 10-19), adults (ages 20-64) and the elderly (ages 65+) were included in the study population, which matched the demographics of the state of Georgia. Georgia has a population of around 10.8 million people, including 1.3 million children and 1.4 million teenagers. To simulate population dynamics while keeping run times realistic, the simulation used one million agents (about one agent for ten persons with similar features in the population). The model depicted an individual's disease progression as well as interactions among households, workplaces, schools, and communities. In Georgia, all children and adolescents aged 0 to 19 were assumed to be in a peer group of similar age (e.g., school, daycare, etc.) [4]. Individuals in their allocated age groups engage with one another at school. Peer groups for the age ranges 0-4, 5-9, and 10-19 were chosen on average as 14, 20, and 30 students, respectively, based on Georgia's typical class sizes.

When using a typical reopening method, delaying the school's reopening date gave the most advantage. Delaying the reopening date by one week reduced cumulative infections in children and youth by at most 3% and all other outcome measures (cumulative deaths, hospitalizations, and cumulative infections in adults) by at most 2% under the standard reopening method. The cumulative mortality, hospitalizations, infections in children and youth [5], and cumulative infections in adults were all reduced by 5%, 7%, and 6%, respectively, by delaying the school reopening date by 5 weeks. Delaying the school's reopening date did not generate as much advantage as the standard reopening strategy in any of the other reopening techniques studied. Delaying the reopening date by one day is the most common strategy used across all school reopening techniques In one week, cumulative mortality were reduced by 0.39%, hospitalizations were reduced by 0.61%, cumulative infections in children and teenagers were reduced by 1.13%, and cumulative infections in adults were reduced by 0.61% [6].

Governments and educational systems have struggled with how to best educate children for academic success while simultaneously attempting to contain COVID19's expansion. While people under the age of 20 appeared to be less affected by COVID19 than adults, they could be COVID19 transmitters, potentially increasing community infection spread if schools returned to in-person instruction, especially given the difficulties in implementing social distancing measures and recommendations for some schools (e.g., poor ventilation in buildings, short supply of disinfectant products, state budget shortfalls, etc.) [7]. Some students have been disproportionately affected by school closures, such as those who lack access to technology at home, lack proper childcare, live in an unsafe home environment, or have traditionally relied on the school system for meals, special education, counseling, and other forms of social or emotional support. School closures may have unexpected repercussions, such as increased worker absenteeism among parents; higher worker absenteeism within the healthcare system may raise the chance of case fatality and the overall mortality rate owing to the pandemic.

Guidelines in the state of Georgia advised that districts with high case numbers reopen schools with online education prior to the start of the fall semester in 2020 [8]. Online learning, on the other hand, has a number of drawbacks. Several rural counties have limited internet connection; for example, Hancock County placed sixth in COVID19 cases per capita, yet only 2% of the county had broadband internet access. By the conclusion of third grade, two-thirds of Georgia students are unable to read proficiently; limited or no access to inperson teaching in the fall might widen this educational gap, with serious long-term repercussions. Furthermore, over half of Georgia's pupils are eligible for free or reduced-price school lunches and many families rely on them. There has been a lot of discussion on the benefits and hazards of returning to in-person instruction in schools in the fall of 2020. "All policy considerations for the coming school year should start with a goal of having students physically present in school," the American Academy of Pediatrics says. For the fall semester, some school districts have postponed opening dates or announced fully online instruction, while others are considering hybrid models like "groups of students to attend on alternating days or weeks, as well as allowing only younger students to attend while older students learn at home [9].

The impact of various school reopening strategies was compared in the presence of a combination of other non-pharmaceutical interventions such as shelter-in- place, voluntary household quarantine, and masking, with varying levels of compliance, as well as universal masking and symptom-based isolation in schools. According to our findings, under the alternate school day, children only, and alternating school day for children reopening techniques, delaying the reopening date would have a minor impact on the peak day and number of new infections. However, delaying the reopening date from August 10 to September 17 under the standard reopening approach might avoid the second peak and cut the number of new children and youth infections by 22%. The alternate school day for children reopening approach increased mortality, hospitalizations, and cumulative infections the least when compared to the schools closed reopening strategy, followed by the children only and finally the alternating school day reopening methods. When compared to the usual reopening method, hybrid reopening tactics such as alternating school days for children, children alone, and alternating school days considerably reduced the percentage of the population infected (by 6%-13%). As a result, using a hybrid reopening method or limiting interactions between student cohorts during in-person education could significantly decrease the transmission of the disease. In a population analysis centered on Washington and Michigan, researchers discovered that online or hybrid training resulted in fewer illnesses than in-person instruction, corroborating the findings [10].

The percentage of the population infected decreased by 13%, 11%, 9%, and 6% in the schools closed, alternating school day for children, children only, and alternating school day reopening strategies, respectively, when compared to schools reopening on August 10 with a regular reopening strategy. In the alternate school day for children only, alternating school day, and regular reopening tactics, deaths increased by 138, 379, 564, and 851, respectively.

In terms of public health as well as social and economic relations, COVID19 has had a considerable impact on society [11]. The population's health and well-being are paramount, yet there is a growing desire to return to inperson instruction in order to assist kids' educational progress. It's vital to understand the impact of various scenarios on public health, student development, and the economy as school systems prepare plans for modes of instruction during an epidemic or pandemic. Our findings imply that reopening schools using a typical reopening method, i.e., allowing all pupils to return to school without strict public health safeguards, would result in a considerable rise in the number of infections, hospitalizations, and deaths. In comparison to the standard reopening method, hybrid in-person and online reopening strategies provide a good balance in lowering illness spread while ensuring access to in-person education, especially if presented as an option to families and instructors who choose to opt-in. In previous research, the impact of non-pharmaceutical public health measures such as workplace closures, voluntary quarantine compliance, shelterin-place, and masking laws was studied and contrasted. According to several researches, the impacts of school closures on public health are similar to those of workplace closures. Our research looked at the impact of various school reopening scenarios in the context of a current pandemic or epidemic with other non-pharmaceutical interventions to provide policy recommendations to decision-makers. Regardless of how school instruction is structured during a pandemic, it is critical to promote physical separation, immunization, and the use of face masks, as well as testing and tracing protocols, to ensure outbreak prevention or early detection in schools.
