“Physicians must be vigilant in evaluating people who have had COVID-19. These patients will need integrated, multidisciplinary care,” Al-Aly stated. The researchers have been in a position to calculate the potential scale of the issues first glimpsed from anecdotal accounts and smaller research that hinted on the wide-ranging unwanted effects of surviving COVID-19.
