Entire streets could be locked down to stop spread of Covid variants, says expert
Entire streets getting locked down could be an effective and crucial way of keeping potential outbreaks of new Covid-19 variants under control, according to an expert.

Hide AdDr Jeffrey Barrett, Director of the Covid-19 Genomics Initiative at the Wellcome Sanger Institute, said that the measure could be the best way forward.
‘Important part of keeping outbreaks small’
Speaking on BBC Radio 4’s Today programme, Dr Barrett said that it was important to deploy “the most effective measures possible” in order to contain these outbreaks.
When asked whether clocking down entire streets would have a medical impact on clusters of cases, the doctor said it “certainly would”.

“Trying to use interventions that might stop asymptomatic transmission may well be an important part of keeping outbreaks of these new variants to be as absolutely small as possible.”
‘The most effective measures possible’
Dr Barrett added that there could be a possibility that new variants of the virus will be “less well neutralised” by vaccines, therefore “it’s really important to be able to try and keep that number as close to zero as possible”.

Dr Barrett said: “As the restrictions are lifted the key thing to watch will be, does that number ever go up sort of week by week, and if so that’s really important to deploy the most effective measures possible to contain those outbreaks.”
‘We need to get ahead of the infection’
Professor Kevin Fenton, London’s Regional Director of Public Health England (PHE), said proactive surge testing for new virus variants is required to help officials “get ahead of the infection”.

“And that is why we have such a proactive programme of screening for and testing for the new variants, and, where we have found, we surge.
“We need to get ahead of the infection, and not keep following behind it.”
