Human characteristics and potential outcomes after infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). In this figure we summarize lifestyle characteristics and the underlying mechanisms as well as potential outcomes before or after SARS-CoV-2 infection. * In the present context age, young and old, means young or old in chronological age, but also could refer to young and old in terms of their lung health (i.e., a chronologically old person may have “young” physiological indices due to healthy lifestyle habits, and vice versa).
