A picture taken on February 26, 2020 shows French professor Didier Raoult, biologist and professor of microbiology, specialized in infectious diseases and director of IHU Mediterranee Infection Institute posing in his office in Marseille, southeastern France. – Raoult reported this week that after treating 24 patients for six days with Plaquenil, the virus had disappeared in all but a quarter of them. The research has not yet been peer reviewed or published, and Raoult had come under fire by some scientists and officials in his native France for potentially raising false hopes.
