The "Brazil variant" -- a more contagious mutation of the coronavirus that emerged in the Amazon late last year -- is fueling fears the pandemic could flare anew, leading several countries to suspend flights from Brazil.- Why is it worrying? -Two certainties, though: it is more contagious than the initial strain of the novel coronavirus, and it can re-infect people who have had the original.
Covid-19 claimed 66,500 lives in Brazil last month -- more than double what had previously been the country's deadliest month in the pandemic, July 2020. It is unclear to what extent P1 is causing the surging death toll. Experts suspect it is more virulent than the original strain but say more research is needed.Researchers say P1 emerged in December last year in or around the northern city of Manaus.
"If the Brazilian authorities had been responsible, they would have closed Manaus like China closed Wuhan," Orellana told AFP.
