More Contagious Coronavirus Strain Now Dominates, Says Houston Study
But there’s little evidence of mutations in virus making it deadlier.
A study conducted in the United States by researchers from Houston Methodist Hospital has found that a more contagious strain of the novel coronavirus now dominates the spread of COVID-19 in the country. The study examined more than 5,000 genomes from viruses recovered in the earliest phase of the pandemic in Houston. It is yet to be reviewed by outside experts, but the study has found that nearly all strains in the second wave had a mutation known as D614G, which led to the increase the number of “spikes” on the crown-shaped virus.
The “spikes” on the novel coronavirus allow it to easily attach itself to cells and infect them. The Houston study has also found that those infected with the newly found strain had significantly higher amounts of the virus on initial diagnosis. What comes as a relief though is that there’s little evidence that the mutations in the virus make it deadlier.
