They included 30 cross‐sectional studies (8491 participants) and 4 case‐control studies (848 participants). Chest CT-scans perform well in identifying COVID-19 in people suspected of having the disease but have limited capability in differentiating COVID-19 from other causes of lung infection. The accuracies of chest X ‐ ray ...

Pérez Velasco's review indicates that non-pharmaceutical interventions, including social distancing and school closings, are profitable for pandemics. Lee's review indicates that physical interventions to prevent transmission of respiratory viruses appear to be cost-effective during an epidemic or ...

A review of randomized trials of psychological and social interventions has been conducted with a total of 2398 participants. The authors concluded in a paucity of eligible prevention studies and the risk of bias and substantial heterogeneity in the studies make the results uncertain.
