Summary

1. The purpose of this trial is to conduct a 2x3 factorial randomized trials, which efficiently allows the parallel conduct of three randomized trials to understand whether metformin, ivermectin, or fluvoxamine, is superior to placebo for preventing Covid-19 disease progression in non-hospitalized adults with SARS- CoV-2 infection.
2. To understand if the active treatment arms are superior to placebo in improving viral load, serologic markers associated with Covid-19, and gut microbiome in non-hospitalized adults with SARS-CoV-2 infection.
3. To understand if any of the active treatment arms prevent long-covid syndrome, PASC (post-acute sequelae of SARS-CoV-2 infection).
