A drug used to deal with COVID-19 could, in truth, be serving to unfold the sickness, scientists have stated.
Molnupiravir works by inflicting mutations within the virus’s genetic data, or genome, a lot of which kill or hurt the virus, lowering the quantity of COVID within the physique.
Used the world over to deal with COVID, it was one of many first antivirals accessible to medical doctors throughout the pandemic.
But researchers who mapped virus mutations throughout world databases, have discovered that some COVID mutations strongly linked to sufferers taking molnupiravir have been very totally different to the same old mutations they noticed, which means it may result in additional an infection.
Christopher Ruis, from the Department of Medicine on the University of Cambridge, stated molnupiravir “belongs to a class of drugs that can cause the virus to mutate so much that it is fatally weakened”.
“But what we’ve found is that in some patients this process doesn’t kill all the viruses, and some mutated viruses can spread,” he stated.
“This is important to take into account when assessing the overall benefits and risks of molnupiravir and similar drugs.”
The research, by researchers on the Francis Crick Institute, the University of Cambridge, Imperial College London, the University of Liverpool, the University of Cape Town and the UK Health Security Agency (UKHSA), additionally discovered the mutations have been extra probably in older age teams in keeping with the usage of the antivirals to deal with people who find themselves extra in danger.
Almost a 3rd (30%) of the occasions in England concerned the usage of molnupiravir, therapy information confirmed.
Theo Sanderson, lead writer and postdoctoral researcher on the Francis Crick Institute, stated: “Our evidence shows that a specific antiviral drug, molnupiravir, also results in new mutations increasing the genetic diversity in the surviving viral population.
“The risk of persistent antiviral-induced mutations must be taken under consideration for the event of recent medication which work in an analogous manner.”

The NHS web site stated molnupiravir is restricted to sufferers “in the highest risk group”.
It works “by stopping the virus that causes COVID-19 from growing and spreading” and is “used to treat early COVID-19 infection and help to prevent more severe symptoms”.
Nearly 230,000 folks within the UK have died and had COVID on their demise certificates because the pandemic started, official figures present.
Across the world, nearly seven million deaths from the illness have been reported to the World Health Organization (WHO).
