In a new article in the JAMA magazine, KA Auger et al. (Katherine A. Auger et al. Association Between Statewide School Closure and COVID-19 Incidence and Mortality in US. JAMA. July 29, 2020) the effectiveness of universal closure. of schools in the United States to reduce the incidence and mortality of coronavirus. The doctors in the therapeutic clinic at the Medical School of the National and Kapodistrian University of Athens, Ioannis Danasis, Panagiotis Malandrakis, Maria Gavriatopoulou and Thanos Dimopoulos, professor of therapy and rector of EKPA, summarize these data.
Despite the uncertainty about the effectiveness of the measure, all 50 US states continued until the total closure of schools in March 2020. The researchers analyzed daily data on incidence and mortality per 1
The cumulative incidence of COVID-19 cases ranged from 0 to 14.75 cases per 100,000 inhabitants at school closure in the various states. School closures were associated with a significant reduction in the incidence of COVID-19 cases by 62% and COVID-19 mortality by 58%. Larger reductions were observed in the states with a lower cumulative effect when the measures were implemented. Typically, states with the lowest cumulative effect showed a 72% reduction in impact compared to states with the highest initial cumulative effect showing a 49% decrease.
The statistical analysis also showed that closing schools in the United States with the lowest cumulative effect resulted in 128.7 fewer cases per 100,000 inhabitants in 26 days and 1.5 fewer deaths per 100,000 inhabitants in 16 days compared to the states with the highest cumulative effect. the effect at the time of the measures. These results suggest that closing the school also had the greatest benefit of reducing incidence and mortality. In summary, school closures have significantly reduced the prevalence and mortality of COVID-19 in the United States, but researchers note that although other non-pharmacological measures in the United States, such as restricting travel and gatherings, may have contributed to some extent to the observed reduction in incidence and mortality. Nor could this study determine the optimal duration of school closure or the optimal combination of this measure with other non-pharmacological interventions to prevent the spread of COVID-19 infection. In a related article, JM Donohue and E Miller (Julie M. Donohue, Elizabeth Miller. COVID-19 and school closures. JAMA. July 29, 2020) note that school graduations have significant academic and financial consequences, and can significantly affect students’ mental and physical health. Therefore, the issue is multifactorial and decisions are made by evaluating all individual aspects based on the continuously updated international scientific information.
