Washington, Sep 26 (Prensa Latina) Scientists at a hospital in Houston, the US, analyzed the structure of SARS-CoV-2 that infected inhabitants of that city in two waves, and noticed a mutation in the strain that makes the virus more contagious, according to reports.
The study, released on the MedRxiv preprint server, states that the mutation helps the virus to spread faster but does not make it more dangerous.
Almost all strains in the second coronavirus wave had a mutation, known as D614G, which increases the number of spikes in the crown-shaped virus and, in turn, allows the virus to bind to and infect the cells, experts say.
Although patients infected with the variant strain had significantly higher amounts of the virus, they did not show that the changes have made the virus more lethal, the report states.
More than 5,000 coronavirus genomes were analyzed to reach those conclusions. They were obtained from recovered Covid-19 patients in the earliest phase of the Houston pandemic and others from a recent wave of infections that is still ongoing.
