Delta covid variant is biggest risk to the world at the moment: Top expert
Live MintThe Delta variant is the fastest, fittest and most formidable version of the coronavirus that causes COVID-19 the world has encountered, and it is upending assumptions about the disease even as nations loosen restrictions and open their economies, according to virologists and epidemiologists. "The biggest risk to the world at the moment is simply Delta," said microbiologist Sharon Peacock, who runs Britain's efforts to sequence the genomes of coronavirus variants, calling it the "fittest and fastest variant yet." Public Health England said on Friday that out of a total of 3,692 people hospitalized in Britain with the Delta variant, 58.3% were unvaccinated and 22.8% were fully vaccinated. In Singapore, where Delta is the most common variant, government officials reported on Friday https://www.reuters.com/world/asia-pacific/vaccinated-people-singapore-make-up-three-quarters-recent-covid-19-cases-2021-07-23 that three quarters of its coronavirus cases occurred among vaccinated individuals, though none were severely ill. Israeli health officials have said 60% of current hospitalized COVID cases are in vaccinated people. "When the vaccines were first developed, nobody was thinking that they were going to prevent infection," said Carlos del Rio, a professor of medicine and infectious disease epidemiology at Emory University in Atlanta.
