This is a prospective, non-randomized, open-label, two-phase design. The primary focus for the study is data collection for index development. This will be done in two phases: the first phase allows for determination of predictor variables that establish the COVID-19 Decompensation Index (CDI) and the second phase establishes performance of the CDI. A participant is considered to have completed the study if he or she completes all phases of the study including the last day of monitoring (day 28).
