NEWS UPDATE On 9 April 2020, the Institut Hospitalo-Universitaire (IHU) Méditerranée Infection, Marseille, released a summary of a non-comparative study in 1061 people who had a positive PCR test result for Sars-CoV-2, the virus responsible for covid-19. Most had mild or no symptoms. All were treated with hydroxychloroquine and azithromycin. Most recovered within 10 days, as is the case, even without treatment, when symptoms are relatively mild. Without a control group, these results can neither confirm nor rule out the value of the treatment administered.
