Hydroxychloroquine + Azithromycin (HCQ + AZ), with optional Zinc, given upon early symptoms, is a cure for COVID-19. This combination is a strong antiviral against the Wuhan coronavirus, quickly reducing the viral load and risk of transmission to other persons. It is a cure both for the treated patient and the epidemic in the country when it adopts this treatment widely, including middle age and young adult population.
Brazilian authorities are inclined to agree that early chloroquine / hydroxychloroquine treatment helps to “bend the curve”:
“There is evidence that in some cities and some states early drug treatment was applied and that was exactly what contributed to the decrease in this curve, in this evolution of the epidemic curve in these states,” he [Executive Secretary of the Ministry of Health, Élcio Franco] said at a news conference. The use of chloroquine in the treatment of covid-19 patients with mild symptoms has been recommended by the Ministry of Health since May 20. [translation via Google Translate]
If a large fraction (30%–70%) of COVID-19 patients receive HCQ-based treatment early and isolate themselves for 5–7 days (until the viral loads drops to a reasonably safe level), the virus reproduction rate R drops below 1. The number of cases drops exponentially, and the epidemic ends. This has happened in Italy, Spain, and other countries that adopted this treatment when the infection was already widespread. When the epidemic ends, COVID-19 will likely remain endemic, but easily treated disease, like a common cold or flu. On the other hand, if presumed COVID-19 patients are not treated early, the coronavirus is free to replicate and spread as now, with the risk that it will mutate into something horrible.
