That French "study" has NOT been validated by other researchers. It was not double-blind, placebo controlled, etc. etc. The paper has not been peer-reviewed. It also only examined 25 patients. Out of 250,000+ cases we have reported to date, 25 patients.
There is OPTIMISM that this might work, but chloroquine and hydroxychloroquine have both shown antiviral properties since the 1960s, for multiple viruses. In repeated studies for decades, not a single one of those in vitro studies has actually translated to any anti-viral activity in actual test cases.
When I see the actual HARD DATA, I'l get fully behind this. Until then, the repeated posting about this drug is giving a lot of fasle hope.
