The most aggressive type of virus was found to prevail in the early stages of the outbreak in Wuhan, the Chinese city where COVID-19 was first detected late last year. But the frequency of this type of virus has decreased since the beginning of January, the scientists said. The researchers noted that the data examined in the study was still “very limited.”
The coronavirus that emerged in Wuhan, China more than four months ago has since mutated, and the new dominant strain spreading across the US appears to be even more contagious, according to a new published study.
The new strain began spreading in Europe in early February before migrating to other parts of the world, including the United States and Canada, becoming the dominant form of the virus worldwide in late March, researchers from the National Laboratory of Los Alamos, in a 33-page report published on BioRxiv last week.
If the coronavirus doesn’t decrease in the summer like seasonal flu, it could further mutate and potentially limit the effectiveness of coronavirus vaccines that scientists around the world are currently developing, the researchers cautioned. Some vaccine researchers have been using the virus’s genetic sequences isolated by health authorities at the start of the outbreak.
The study has not yet been peer-reviewed, but the researchers noted that the news of the mutation was of “urgent concern” considering the more than 100 vaccines in the pipeline to prevent Covid-19.
In early March, researchers in China said they found that two different types of coronaviruses could be causing infections worldwide.
In a preliminary study published Tuesday, scientists from the Peking University Faculty of Life Sciences and the Shanghai Pasteur Institute found that a more aggressive type of the new coronavirus had accounted for about 70% of the strains tested, while that 30% had been associated with a less aggressive one.

The researchers said their results indicate that the development of new peak variations in COVID-19 cases was “likely caused by mutations and natural selection in addition to recombination.”

“These findings strongly support the urgent need for more immediate and comprehensive studies that combine genomic data, epidemiological data, and graphical records of the clinical symptoms of patients with coronavirus disease 2019 (COVID-19),” they said.
The researchers cautioned that the data examined in the study was still “very limited,” emphasizing that follow-up studies of a larger data set would be needed to gain a “better understanding” of the evolution and epidemiology of COVID-19.
The findings were published in the National Science Review, the journal of the Chinese Academy of Sciences.

Los Alamos researchers, with the help of scientists from Duke University and the University of Sheffield in England, were able to analyze thousands of coronavirus sequences collected by an organization promoting rapid data exchange of all influenza viruses and the coronavirus.
Employees of gas stations, supermarkets, laundries, home delivery or mechanics, the Hispanic community occupies many of the key positions that allow the United States to continue operating at its worst.
To date, researchers have identified 14 mutations.
The mutation affects the spike protein, a multifunctional mechanism that allows the virus to enter the host.
The research was supported by funds from the Medical Research Council, the National Institute for Health Research and Genome Research Limited.
