BRASILIA: Brazil's health ministry recommended on Wednesday (May 20) using chloroquine and hydroxychloroquine to treat even mild cases of COVID-19, a treatment President Jair Bolsonaro has pushed for despite a lack of conclusive evidence of their effectiveness.

New federal guidelines released by the ministry recommend doctors prescribe the anti-malarial drugs from the onset of symptoms of coronavirus infection, together with the antibiotic azithromycin.
