Brazil’s President Jair Bolsonaro's lawmaker son said Friday he had contracted the coronavirus -- the third member of Brazil's delegation to the UN General Assembly in New York to test positive.

Eduardo Bolsonaro, 37, said on Twitter he was feeling well and had "started to treat myself" without specifying what he was using, reports AFP.

He cited his infection as evidence in his campaign against the coronavirus vaccine passport recently introduced in some Brazilian cities.
