Large genetic study reveals new, more contagious strain of coronavirus, Science News
A study to understand the structure of the new coronavirus published on Wednesday noted that a new strain of the deadly virus is more contagious.
Research led by Houston Methodist Hospital examined 5,000 genomes of viruses recovered from the start of the outbreak in Houston, US, and from a current wave of infections.

He says, however, that although there is a continued accumulation of mutations, there is little evidence to suggest that they have made the virus more deadly than it was before.

The study found that almost all of the second-wave strains had a mutation, known as D614G, that increased the number of “spikes” present on Covid-19.
The spikes are what lead to the virus binding to other cells, thus breaking up the infection.
However, it must be subject to peer review.
The researchers said the variant strain contained substantial amounts of Covid-19 when initially diagnosed.
The study also noted that in some areas there were many mutations, possibly suggesting that the virus was changing order to counter the body’s immune system.
The research is also considered the largest collection of genetic sequences from the virus in the United States to date.
