Abstract
Social Intervention by the Numbers: Evidence Behind the Specific Public Health Guidelines in the COVID-19 Pandemic.
Highlights
Coronavirus disease 2019 (COVID-19) has rapidly become a worldwide pandemic ushering in a global health and economic crisis
For practical and perhaps ethical reasons, the clinical efficacy of these public health measures for managing pandemics has not been demonstrated in randomized controlled clinical trials
Observational studies have credited nonpharmaceutical interventions with slowing the spread of COVID-19 in China and on the west coast of the United States.[2,3,4]. These apparent salutary effects in the COVID-19 pandemic mirror the benefits of similar interventions observed in prior influenza pandemics.[5]
Summary
Coronavirus disease 2019 (COVID-19) has rapidly become a worldwide pandemic ushering in a global health and economic crisis. In addition to general measures such as closure of schools and nonessential businesses, public health guidelines for managing COVID-19 include a series of specific, quantitative recommendations that are the focus of this analysis (Table 1).[6,7,8] Among these are explicit rules regarding interpersonal distancing (6 feet), limitation of group gatherings (10 people), duration of quarantine for exposed individuals (14 days), and duration of handwashing (20 seconds).
