Two new strains of coronavirus originating in the United States have been found

BEIJING, Jan. 14 (Xinhua Liu Xia) According to the U.S. Consumer News and Business Channel website reported on the 13th, researchers at Ohio State University on Wednesday reported that they have found two new strains of the new coronavirus that may originate in the United States, one of which quickly became the main new coronavirus variant in Columbus, Ohio, in the three weeks from the end of December to the beginning of January this year.
, like the new strains first detected in the UK, appear to have increased the infectiousness of the new coronavirus, but did not appear to reduce the effectiveness of the vaccine, the researchers said.
researchers found evolutionary evidence of the variant in Columbus, Ohio.
reported that the new coronavirus may have originated in the United States because it contains three genetic mutations that "have never been seen in a coronavirus before."
Dan Jones, deputy director of molecular pathology at Ohio State University and lead researcher on the study, said: "This new variant has the same genetic basis as the early cases we studied, but these three mutations represent a huge evolution, and we know that the mutation does not come from the UK or South Africa.
," Jones added, it's too early to say how contagious the virus may be in Columbus.
but the researchers believe it may be more contagious based solely on the speed at which it has spread over the past few weeks.
, chief scientific officer at Wexner Medical Center in Ohio and co-author of the latest study, said there is no data to suggest that the two new strains affect vaccine effectiveness.
it is important that we do not overreact to this new variant until we have more data," he said in a statement.
need to understand the effects of mutations on the effectiveness of virus transmission, how prevalent the strain is in the population, and whether it has a greater impact on human health.
month, the White House Coronavirus Task Force warned states that a new variant could be spreading in the United States.
the New York Times, the hypothesis was put forward by Task Force Coordinator Dr. Deborah Burks on the basis of the severity of the outbreak in the United States in recent months.
, chief medical officer of the Ohio Department of Health, said in a statement that the department was "not surprised" to find a new strain of the virus in the state.
researchers warn that as the virus spreads around the world, it has more opportunities to mutate, potentially becoming more contagious or making existing treatments and vaccines less effective.
