Confirmed coronavirus deaths in Brazil's largest city spike by over 400%

Coronavirus deaths in São Paulo, the largest city in Brazil and the Western Hemisphere, have increased by over 485% since the city's health department began keeping track in April.

The big picture: Prolonged lapses in testing and tracking, documented by the Washington Post in April, have led to severely undercounted death tolls in Brazil. The country is reporting the third-most confirmed COVID-19 cases in the world, per Johns Hopkins data — only behind Russia and the U.S.

• Over 65,000 of the country's confirmed cases are in São Paulo, per Johns Hopkins — an infection rate that overshadows all other cities in the country.

What's happening: 90% of ICU beds in São Paulo are occupied and "suspected deaths from COVID-19 have surged more than fivefold in the past month," the Washington Post reports. Meanwhile, fewer people are currently following the city's stay-at-home order.

• Brazil's President Jair Bolsonaro last week challenged state governors who vowed to defy his push to reopen businesses across the country.
• São Paulo plans to build 700 more ICU beds and work with private hospitals to take in patients, the Post reports.
