Modern coronavirus has jumped from bats to humans with ‘little change’, say scientists

The ‘novel coronavirus’ ‘with little or no change’ has been transformed into humans from bats, according to a new study which shows that the ability of the virus to spread from one person to another has increased. change in previous flying mammals. jumping to the new human guest.

The study, published in the journal PLOS Biology, evaluated hundreds of thousands of sequencing genomes of the SARS-CoV-2 virus and found that for the first 11 months of the COVID-19 pandemic, there was very little ‘ important genetic mutation ‘observed in the coronavirus.

However, he noted that some modifications such as the D614G mutation, and a similar print in the virus’s spike protein have affected its biology.

” This does not mean that no changes have occurred, non-critical mutations accumulate and surf around millions of transmission events, as they do in all viruses, ” first study author Oscar Maclean of the Glasgow University Center for Virus Research in Scotland explained.

But the scientists said it was’ surprising ” how transmissible SARS-CoV-2 has been from the beginning. Viruses that jump to a new host species usually take some time to get changes to become as viable as SARS-CoV-2 at release, and most never go unnoticed. beyond that level, resulting in localized spills or localized outbreaks, ” said Sergei Pond, another co – author of the study from Temple University in the US.

Analyzing the mutations made by the novel coronavirus and associated sarbecoviruses – the group of viruses belong to the COVID virus from bats and pangolins – the scientists found evidence of a moderate change, but all before SARS-CoV-2 appeared in humans. Based on this observation, the researchers said that SARS-CoV-2 came with a ready ability to capture humans and other mammals, with these properties likely to evolve into bats before jumping into humans.

” While ‘undetected’ intermediate sex cannot be reduced, together, our results support the SARS-CoV-2 promoter to be able to effectively distribute human-like as a result of its ever-changing history in bats, not humans, it has created a relatively common virus, ” the scientists in the study wrote.

Although the novel coronavirus is still plagued by the human immune response in most diseases, the scientists warned that it is now moving away faster than the January 2020 variant that was used in all routine vaccines to build immunity.

Conventional vaccines will continue to work against most of the circulation variables, but as more time passes, and as the difference between the numbers of vaccinated and non-vaccinated people increases, they said increased chance of the virus escaping vaccines.

The first race was to develop a vaccine. The race is now to get the global vaccine as soon as possible, ” said David L Robertson, lead author of the study from Glasgow University.
