President Bolsonaro of Brazil has become the latest world leader to test positive for coronavirus. Brazil has the second-highest number of cases and deaths in the world, after the United States.
Mr Bolsonaro has been consistently dismissive of the threat posed by the pandemic and has claimed that lockdowns are more damaging than the virus itself.
Brazil and South America are now among the worst-affected parts of the world.
