Corona Virus, How Has It Affected Your Area So Far?

First of all, i want to say that I appreciate your enthusiasm. I had read that study before, and a colleague of mine even brought it up during one of the multidisciplinary meetings we had about COVID-19 in my hospital. Long story short, that's an "in vitro" model, meaning it works on the cells cultivated on a petri dish. We have no guarantee that's how it works in the human body (in vivo), mostly because almost every compound you take (orally or not) gets processed/modified by your liver to a certain extent. There are also other factors that play a role, like bioavailability and how well a drug can reach and stay in the organs you want it to go.
Right now, the general consensus is that, speaking about COVID-19, HCQ is proving effective for its immunomodulatory properties (decrease of the interleukin cascade, TNF-alpha expression and so on) rather than its (dubious) antiviral properties. Keep in mind, HCQ is not even our best drug in fighting severe cases of COVID-19, as it's unclear if it helps when the disease has progressed to respiratory failure. In those cases we tend to use Tocilizumab, which is an immunomodulatory drug, in a single administration.
The role of inflammation in COVID-19 pathogenesis and progression is becoming very clear over time, even when looking at its epidemiology: women and children (weaker immune system compared to adult males) usually get less severe forms, as well as younger non-obese subjects (body fat produces several interleukines, among all IL-6; while inflammation indexes usually rise with the age, mostly due to chronic damage to cells' DNA by oxygen radicals, which makes them release pro-apoptotic signaling and flags them to white cells).

Wow a friend of mines mother just passed away recently. She had contracted the virus and had asthma and lived on Long Island. Crazy when it happens close to home.
