As coronavirus cases explode in Brazil, so do investigations into alleged corruption

(CNN)As Brazil's coronavirus cases surge by the tens of thousands each day, the country is contending with a parallel outbreak -- a flurry of corruption investigations into the alleged misuse of public money rapidly shelled out for Covid-19 emergency procurement.

The investigations have reached all levels of government, including three state governors who have come under federal scrutiny in the past two months. Nearly 1,500 federal criminal judicial proceedings have also been opened into coronavirus-related cases, including investigations into misuse of federal funds, fraud, overpricing, and money laundering, according to a summary the federal prosecution office shared with CNN.

Sao Paulo officials paid as much as $40,000 each for some ventilators, while the cheapest were bought for $20,000, according to the Brazilian Office of the Comptroller General, which notes that the average price per ventilator paid across Brazil is around $16,000.
    The state government has said the purchases complied with legal require
