Initially, the omicron variant caused great concern around the world, mainly due to its viscosity. 32 mutations in its spike protein suggested it might resist current vaccines. But 12 months later, the number of Covid-19 cases began to decline in all countries of the world.
Now experts are verifying whether a new variant of Covid-19 could emerge this winter, which would cause a new wave of infections. The name Pi is quite logical: it is the next letter of the Greek alphabet, after omicron.
At the African Health Research Institute, leading scientists from the UK, Japan and Australia came together to discuss the prospects for Covid-19 among other viral diseases such as HIV.
Professor Wendy Barclay, a virologist at Imperial College, told the Telegraph: “Could we expect another potentially dangerous variant of Covid-19 to completely replace omicron? Nobody knows, but I still think it’s not over yet. We. we still don’t know much about this virus! “
Greg Towers, a professor at University College London, said he hoped that while there may be more changes in the genetic makeup of the virus, it would not cause serious diseases to return.
Meanwhile, University of Warwick virologist Professor James Young said reducing testing in the UK could leave officials unprepared for new variants like Pi.
