Scientists call for more genetic sequencing of emerging variants like P1 to bring pandemic under control
The coronavirus variant originally found in Manaus in Brazil and detected in six cases in the UK was able to infect 25% to 61% of the people in the Amazonian city who might have expected to be immune after a first bout of Covid, researchers say.
The extent to which P1 can evade the immune system, and potentially vaccines, emerged as the UK health secretary said the hunt for one person who tested positive for P1 – but did not leave contact details – had narrowed to 379 households in the south-east of England.
