Research had been slower on P1 since its discovery in late December, leaving scientists unsure of just how much to worry about it. "I've been holding my breath," said Dr Bronwyn MacInnis, a public health researcher at the Broad Institute. Now three studies offer a sobering history of P1's meteoric rise in the Amazonian city of Manaus. It likely arose there in November and then fuelled a record-breaking spike of coronavirus cases.
