Researchers have discovered two new variants of coronavirus that may have originated in the United States in Ohio



Ohio researchers announced on Wednesday that they have identified two variants of the coronavirus, which may have originated in the United States.

According to the variant strain first identified by researchers at Ohio State Wexner Medical Center, a patient in the state identified one of the new strains. “Therefore, researchers do not yet know the prevalence of this strain in the population.” .

Officials said the new mutation “carries the same mutation as the British strain, but it is most likely caused by a strain that already exists in the United States.

In addition, the researchers also discovered the so-called “evolved strain with three new mutations”

;, which has “become the main virus of Columbus within three weeks of late December and January 2020.”

Dr. Dan Jones, vice chairman of the Department of Molecular Pathology and lead research author, said: “This new Columbus strain has the same genetic backbone as the earlier cases we studied, but these three mutations represent significant evolution.” statement. “We know that this transition did not come from the British or South African branch of the virus.”

They said that the variant of Columbus was named COH.20G/501Y.

The research results are published as a pre-print server BioRxiv and have not yet been peer reviewed.

They said that researchers at the Medical Center identified new strains by sequencing the genome of the SARS-CoV-2 virus. This is what they have been doing since the beginning of the pandemic, with the purpose of paying close attention to the “evolution of the virus.” .

“Like the UK strain, the mutations detected in both viruses will affect the spikes scattered on the surface of SARS-Cov-2. The spikes allow the virus to attach and enter human cells. Like the UK strain, Columbus virus Mutations in the strain may make the virus more infectious and make it easier to spread from person to person.”

Experts worry that these mutations may affect the efficacy of existing COVID-19 vaccines and therapeutics. However, the study’s co-author, Ohio State Wexner Medical Center Chief Scientific Officer Peter Moller said: “We have no data to believe that these mutations will have any impact on the efficacy of vaccines currently in use.” In a statement Zhong served as the dean of the medical school.

Mohler continued: “It is important that we do not overreact to this new variant until we have more data.” “We need to understand the impact of the mutation on the spread of the virus, the prevalence of the strain in the population, and whether it is harmful to human health. Have a more important impact.”

He said that monitoring the evolution of the virus is critical to understanding how mutations affect the way doctors diagnose and treat the virus.

Jones added: “The virus will naturally mutate and evolve over time, but the changes in the last two months are more pronounced than the first few months of the pandemic.”
