News Summary
Research from Oxford University’s Department of Statistics and the Leverhulme Center for Demographic Science examines the trade-offs of school closures during the COVID-19 pandemic. While preventing approximately 77,200 deaths, these closures led to significant long-term economic losses valued at about £1.6 trillion. The study highlights the importance of balancing health and educational outcomes, advocating for optimized non-pharmaceutical interventions to mitigate future crises effectively.
Oxford – New research conducted by Oxford University’s Department of Statistics and the Leverhulme Center for Demographic Science reveals that while school closures during the COVID-19 pandemic in the United States helped prevent a significant number of deaths, they also produced substantial long-term economic drawbacks. The study highlights that the closures resulted in approximately 77,200 averted COVID-19 deaths, while simultaneously inflicting an estimated £1.6 trillion ($2 trillion) in economic losses due to detrimental effects on education.
The study focused on various non-pharmaceutical interventions (NPIs) enacted across U.S. states during 2020, prior to vaccine availability. Researchers from Oxford and the University of Washington assessed the impact of eleven different NPIs by combining disease modeling with economic analysis. Findings indicated that school closures were effective in reducing transmission rates of the virus by 8.2%, but the educational costs were profound. Students experienced a loss of about 0.35 school-years of learning, with certain states maintaining school closures throughout nearly the entire academic year of 2020–2021.
In contrast, the research indicates that mask mandates proved to be more effective, yielding a 19% reduction in transmission rates while incurring minimal economic expense. Testing and contact tracing programs also emerged as efficient strategies relative to their implementation costs. Lead author Nicholas Irons noted that despite the unprecedented challenges posed by the pandemic, the policy response to control the virus was not optimal overall.
The study also explored the potential economic implications of a more strategic mix of interventions. It suggested that an optimal combination of NPIs could have lessened the total economic burden of the pandemic in the United States from £3.7 trillion ($4.6 trillion) to £1.5 trillion ($1.9 trillion) while saving over 100,000 additional lives. Co-author Adrian Raftery remarked on the necessity for improved national surveillance data within the U.S., akin to that employed in the UK during the pandemic, which could enhance response efforts in future health crises.
Overall, the findings provide essential insights for pandemic preparedness and response, emphasizing the need for a balance between health outcomes and economic stability. Researchers recommend rapidly deploying testing and contact tracing, implementing mask mandates, observing social distancing protocols, and undertaking targeted facility closures as effective strategies for managing future outbreaks.
The research paper is titled “Optimal pandemic control strategies and cost-effectiveness of COVID-19 non-pharmaceutical interventions in the United States” and is now available in BMC Global and Public Health.
