"We have known about COVID-19 for about four months; it can take years to plan, complete, and publish a randomized, double-blind controlled study. However, in 2005, the CDC Special Pathogens Branch described three mechanisms by which chloroquine might work and have both a prophylactic and therapeutic role in coronavirus infections. More than 20 relevant studies have been published in journals indexed in PubMed between Jan 28 and April 20, 2020."
