Coronavirus Mutating, Potentially Evolving, Shows Study Amid US Surge

NDTV:

Scientists in Houston on Wednesday released a study of more than 5,000 genetic sequences of the coronavirus, which reveals the virus's continual accumulation of mutations, one of which may have made it more contagious.

That mutation is associated with a higher viral load among patients upon initial diagnosis, the researchers found.

The study, which has not been peer-reviewed, was posted Wednesday on the preprint server MedRxiv. It appears to be the largest single aggregation of genetic sequences of the virus in the United States. A larger batch of sequences was published this month by scientists in the United Kingdom, and, like the Houston study, concluded that a mutation that changes the structure of the "spike protein" on the surface of the virus may be driving the outsize spread of that strain.

The new report did not find that these mutations have made the virus deadlier. All viruses accumulate genetic mutations, and most are insignificant, scientists say. Coronaviruses such as SARS-CoV-2, which causes the illness covid-19, are relatively stable as viruses go, because they have a proofreading mechanism as they replicate.
