Somewhat Misleading Article.
Problems:
1. Hydroxychloroquine is not the same thing as Chloroquine. The hydroxy version has fewer side effects. Which one was used in Brazil?
2. The Hydroxychloroquine therapy used most successfully by French epidemiologist, Professor Didier Raoult, and by physicians in NYC, combined it with Zitheromyecin and Z-pak zinc, as well as vitamins such as A, D and C. That is what produced the very best results, not Chloroquine or Hydrochloroquine all by itself.
3. If irregular heartbeat is all that was produced as side effects, that is really no huge problem, usually corrected by increasing intake of magnesium supplements or a diet high in green leafy vegetables. Or Hawthorne herb in modest doses.
4. Mainstream medicine has a long history of fraudulent "replications" of successful clinical trials by modifying the protocols to produce a negeative result. The most famous was how the Vitamin C therapy developed by Linus Pauling, for cancer treatment, was "replicated" by using it on terminal cases that had already gone through the wringer of surgeries, chemotherapy and radiation treatments, and were set to die. "Testing for miracles" did not produce the results that Pauling clearly stated could only be obtained by using Vitamin C therapy in the early stages of the disease, when the patient's immune system was still intact.
5. The CDC in recent weeks has advocated counting all kinds of deaths as "Covid19" without testing or rational reasons, other than to boost up the numbers of infected and dead. This is fraud, and the numbers being floated around by both media and "official sources" in the USA can no longer be trusted, anymore than the numbers released by the Chinese Communist Party.
6. I'd like to see Space.com address the totalitarian agendas of the vaccine pushers, such as Bill Gates or Anthony Fauci, they want to keep everyone socially disconnected with masks and such as a nearly permanent feature of American life. They want mandatory vaccines, where doctors team up with police forces and SWAT teams to force people to take them, to break into homes and grab dissenting people, to have "vaccine identity papers" which show if you are an obedient sheep, as a necessity to get a driver's license, to get on an airplane, or go to a concert, sports game, conference or even into the local grocery store. In short, the Chinese Communist system of social demerits would be applied to the Western democracies, under the fraudulent banner of "health care".
