Sao Paulo governor tests positive for coronavirus
Governor Joao Doria, an early and vocal advocate of lockdown measures to contain the virus, is a leading opponent of far-right President Jair Bolsonaro, who regularly downplays COVID-19 and argues the economic damage of business closures will be worse than the disease.
Doria, 62, said in a video posted on Twitter that he was "completely asymptomatic."
"I just received my sixth test result for COVID-19 and unfortunately it came back positive," he said.
"I feel fine. I'm going home... and will continue holding meetings remotely with all sectors of the Sao Paulo government for the next 10 days."
Brazil has the second-highest number of coronavirus infections and deaths in the world after the United States, at more than 3.1 million and 103,000 respectively.
Bolsonaro himself tested positive for the virus last month, spending three weeks in quarantine. Eight of his cabinet ministers and 11 of Brazil's 27 governors, including Doria, have also tested positive.
Home to 46 million people, Sao Paulo state is Brazil's industrial hub and also the epicenter of its coronavirus outbreak, with nearly 640,000 infections and more than 25,000 deaths.
The state began a gradual reopening process in June, despite warnings from medical experts that it was still too soon.
