Personally I'm witholding judgment until the results of the PATCH trial (https://clinicaltrials.gov/ct2/show/NCT04329923) arrive, as it'll finally give us some decent statistical power, and be a full, double-blind RCT. It also has multiple study arms (health-care worker prophylaxis, home-quarantined early stage, hospitalized later-stage), so if it turns out that HCQ is effective but that by the time patients are hospitalized it's too late, as some are now suggesting, we should finally know with some degree of certainty.
