"Brazil: President Jair Bolsonaro, refused to comment on the number of deaths from the new Coronavirus: 'I am not an undertaker,' he answered a journalist who asked him about the balance of victims and infected."
The truth is that the number of deaths in the country continue to rise, while tensions between the administration of ultra-right-wing Jair Bolsonaro and the governors grow.
Despite the death toll, Bolsonaro is once again questioning the social isolation measures unilaterally applied by the governors.
"There is no point in the population wanting to flee from COVID-19, if 70% of them will contract the disease anyway," the president said.
Bolsonaro continues to blame the press for maximizing the effects of the pandemic to increase fear and bewilderment.
To date, Brazil reports a total of 2,575 deaths and 40,581 infections.
