In the present study, multivariate analysis performed using Cox regression modeling and propensity score matching to control for potential confounders affirmed that treatment with hydroxychloroquine alone and hydroxychloroquine in combination with azithromycin was associated with higher survival among patients with COVID-19. Patients that received neither medication or azithromycin alone had the highest cumulative hazard. The benefits of hydroxychloroquine in our cohort as compared to previous studies maybe related to its use early in the disease course with standardized, and safe dosing, inclusion criteria, comorbidities, or larger cohort. The postulated pathophysiology of COVID-19 of the initial viral infection phase followed by the hyperimmune response suggest potential benefit of early administration of hydroxychloroquine for its antiviral and antithrombotic properties. Later therapy in patients that have already experienced hyperimmune response or critical illness is less likely to be of benefit.

I take extra Vitamin C and D3 every day in addition to my regular vitamins I suck on zinc tabs whenever I get any indication of something starting up. Cough or scratchy throat.
In the meantime, I have yet to have any cold or flu for years due to this protocol. My husband was sick in Jan 2019 for a month coughing. Probably was COVID. I started to get it and nipped whatever it was by adding the zinc zinc every day for several days. Never got sick.
The mask wearing, however, has caused me to have some problems with sinus issues from bacteria. I use a nettie pot with distilled warm water to which I add a few drops of colloidal silver into the pot. It sometimes takes a few days of this to clear out the infection.
