Brazil has registered a record 100,158 new coronavirus cases within 24 hours, the Health Ministry said, underlining the scale of a snowballing outbreak that is becoming a major political crisis for President Jair Bolsonaro.

The record caseload, along with 2,777 more Covid-19 deaths, comes a day after Brazil surpassed 300,000 fatalities from the pandemic, the world’s worst death toll after the United States.

Critics, including senior lawmakers with ties to the president, are increasingly blaming Bolsonaro for his handling of the pandemic. He has drawn sharp criticism for his efforts to block lockdowns, scorn masks and sow doubts over vaccines.
