>I am perplexed at the complete and utter avoidance from western countries (including US, Britain and Israel) of these. Dexamethasone's effects were discovered by a study in the UK, and: "Changes in the NHS covid-19 treatment protocol were soon announced based on these results". My wife confirms this, she's a nurse. https://www.bmj.com/content/370/bmj.m2648 https://www.bmj.com/content/370/bmj.m2648 Hydrochloroquine is not effective as a Covid-19 treatment: "However, available evidence does not support the use of this medication in the prevention or treatment of COVID-19." https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(20)30390-8/fulltext https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9... As for ivermectin: "Ivermectin inhibits the replication of SARS-CoV-2 in vitro at concentrations not readily achievable with currently approved doses. There is limited evidence to support its clinical use in COVID-19 patients." Although they do recommend further studies. It seems it could be useful, but there are alternative treatments available now that are more effective. https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(20)30464-8/fulltext https://www.thelancet.com/journals/eclinm/article/PIIS2589-5...
