The search for the missing case of the Brazilian CCP virus variant has narrowed down to just 379 households in southeast England, UK Health Secretary Matt Hancock said on Tuesday.
“We’ve identified the batch of home test kits in question. Our search has narrowed from the whole country down to 379 households in the southeast of England, and we’re contacting each one,” he said.
A number of potential cases had come forward following the government appeal, he said.
But Hancock told Parliament that incidents like this “are rare and only occur in around 0.1 percent of tests.”
He said the five other people who tested positive for the Brazilian variant “quarantined at home as they were legally required to do,” and the authorities have been in contact with them.
As a precaution, health authorities have stepped up testing and sequencing in South Gloucestershire, where two of the cases were found.
“We have no information to suggest that the variant has spread further,” Hancock said.
But he said the COVID-19 vaccines currently in use in the UK have not yet been studied against the Brazilian variant.
“We’re working to understand what impact it might have, but we do know that this variant has caused significant challenges in Brazil,” he said.
“These include E484K, which is predicted to make existing antibodies to SARS-CoV-2 less effective, as well as N501Y, which is potentially linked to increase transmissibility,” he said.
