it might be that this author is rushing to confirm something that other research is already suggesting. south korea and italy are both using hydroxychloroquinine at scale and US hospitals are also starting to use it.

In Canada it requires a prescription but plenty of countries have it over-the-counter.

Toclizumab is a different story, since there's now a proper trial with 300 patients starting on Thursday.
