Common public screening methods unreliable; student athletes may need heart test after COVID-19

Common public screening methods unreliable; student athletes may need heart test after COVID-19COVID-19 screening tests used at airports, schools, and other public places are not particularly effective, a large analysis shows. Researchers synthesized the evidence from 22 studies of various screening methods, including taking people's temperature, asking about symptoms, travel history and exposure to infected or possibly infected people, and combinations of those and other approaches. With these popular screening methods, "a high proportion of infected individuals may be missed and go on to infect others, and some healthy individuals may be falsely identified as positive, requiring confirmatory testing and potentially leading to the unnecessary isolation of these individuals," the researchers wrote on Tuesday in a review for The Cochrane Library.
