Health systems in most of Brazil’s largest cities are close to collapse because of Covid-19 cases, its leading health institute warns. More than 80% of intensive care unit beds are occupied in the capitals of 25 of Brazil’s 27 states, Fiocruz said. Experts warn that the highly contagious variant in Brazil may have knock-on effects in the region and beyond. “Brazil is a threat to humanity,” Fiocruz epidemiologist Jesem Orellana told AFP news agency. The country has recorded more than 266,000 deaths and 11 million cases since the pandemic began.
