Brazil’s official Covid-19 death toll has more than doubled since I last wrote, four weeks ago, with 51,407 deaths and more than a million confirmed cases. According to the first nationwide study, the real number of cases could be seven times that, but the research teams charged with investigating were harassed and detained, and 800 tests were destroyed. President Bolsonaro, meanwhile, is still pushing hydroxychloroquine and making jokes about the ‘minor flu’. The federal court in Brasilia has ordered that Bolsonaro be fined every time he appears in public without a mask.
