SAO PAULO: Isolated in his office at city hall, Sao Paulo Mayor Bruno Covas is waging a war on two fronts: the cancer survivor is also leading the fight against coronavirus at its epicenter in Latin America.

It's safe to say February 26, 2020 is a day the 40-year-old mayor won't forget anytime soon: just as he was starting immunotherapy for lymphoma - his third cancer in as many months - he got the news that Latin America's first case of the new coronavirus had been confirmed in his city.
