Seconal Posted April 16, 2021 Share Posted April 16, 2021 (edited) COVID-19: Indian double mutation variant arrives in Britain and has 'hallmarks of very dangerous virus'. As yet, it is unknown what impact the two mutations would have on the effectiveness of existing vaccines. The new Indian variant of the COVID virus that's been detected in the UK has all the hallmarks of a very dangerous virus. It has two new significant mutations in the spike protein that help it infect cells and evade the immune system. The combination - called a double mutant - is a particular concern. As yet it is unknown what impact they would have on the effectiveness of the existing vaccines. The discovery of so many cases of the Indian variant in the UK highlights the flaw in relying on a traffic light system for controlling international spread of potentially dangerous viruses. India is not on the red list so there is no requirement for hotel quarantine. Instead returning travellers are required to take two COVID tests and quarantine at home for 10 days. But if people don't fully quarantine there is a risk of the virus escaping. https://news.sky.com/story/covid-19-indian-double-mutation-variant-arrives-in-britain-and-has-hallmarks-of-very-dangerous-virus-12276922 Locking down entire streets could be an important way of keeping outbreaks of new Covid variants under control, an expert has suggested. Dr Jeffrey Barrett, director of the Covid-19 Genomics Initiative at the Wellcome Sanger Institute, said using interventions to minimise asymptomatic transmission could be crucial. Speaking on BBC Radio 4’s Today programme, Dr Barrett said it was important to deploy “the most effective measures possible” to contain these outbreaks. When questioned if shutting down entire streets would have a medical impact on clusters of cases, he responded: “Well it certainly could, because one of the trickiest parts of this virus overall is, of course, some individuals who are infected don't have symptoms and so they can transmit. “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." He added there could be a “chance” new variants will be “less well neutralised” by vaccines, so “it's really important to be able to try to keep that number as close to zero as possible”. Restrictions have so far kept the number of new variants “very small”, he said, adding: “And 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 it's really important to deploy the most effective measures possible to contain those outbreaks."
