Another Guardian article - weekend read
https://www.theguardian.com/world/2021/nov/21/is-delta-the-last-covid-super-variant
Just picked out a few highlights.
"In recent weeks, concerns have emerged that the use of new antiviral pills, in particular Merck’s molnupiravir, could contribute to this by actively encouraging Sars-CoV-2 to evolve. Molnupiravir works by interfering with the virus’s ability to replicate, littering its genome with mutations until it can no longer reproduce. Some virologists have argued that if any of these viral mutants survive and spread to others, it could theoretically spur the rise of new variants."
" It has been speculated that the widespread use of convalescent plasma early in the pandemic was responsible for driving the emergence of variants.
“We don’t know for sure, but a lot of plasma was used and it was potentially one of the drivers for the variants,” he says. “It was used very widely in Brazil, India, the UK and the US, all of whom developed their own sets of variants.”
" If you look at the variants we’ve had, they have all emerged in countries with very high, uncontrolled transmission – India, the UK, Brazil. There’s a reason why we haven’t heard of a Singaporean or South Korean variant.”
"We expect the virus to keep evolving.”
