randomized trial finds hydroxychloroquine did also prevent covid-19
\"this randomized trial did not demonstrate a significant benefit of hydroxychloroquine as postexposure prophylaxis for covid-19,\" the authors of the study, a team of us and canadian researchers, wrote in the paper.", "analysis of the two treatment groups showed that the difference in the incidence of new illness compatible with covid-19 was not statistically significant11.8% of those receiving hydroxychloroquine (49 of 414) got sick, compared with 14.3% of those receiving placebo (58 of 407).", 


































"\"in the current trial, the long delay between perceived exposure to sars-cov-2 and the initiation of hydroxychloroquine ( 3 days in most participants) suggests what was being assessed was prevention of symptoms or progression of covid-19, rather than prevention of sars-cov-2 infection,\" myron cohen, md, of the institute for global and infectious diseases at the university of north carolina, wrote.")
