Newly recognized pressure of COVID in US could also be most contagious but – Thebritishjournal

Scientists from Southern Illinois University have identified a third US variant of the virus that causes COVID-19 — and it may be the most contagious strain yet, researchers said Thursday.

The homegrown mutation, dubbed 20C-US, is believed to be responsible for up to 50 percent of all US cases — hitting the Midwest the hardest, researchers said in a press release.

“It’s here. We found it,” said Keith Gagnon, an associate professor of biochemistry at SIU Carbondale. “It’s definitely home-grown and widespread.”

Gagnon said he and his team traced the strain back to Texas, where it first appeared in May.

The mutation has a keen ability to process viral proteins along with strong “RNA genome integrity,” the researchers said — making it frighteningly efficient at spreading.

“It might be more easily transmissible than other variants, and its impact on vaccines is uncertain,” the press release states.

The findings come a day after scientists at Ohio State University said they discovered a different strain of the COVID-19 virus — which carries a mutation similar to the UK strain.

The results of the 20C-US study were published in the online journal bioRxiv.org on Wednesday.

“We predict that 20C-US may already be the most dominant variant of SARS-CoV-2 in the US,” the article states.

“The ongoing evolution of 20C-US, as well as other dominant region-specific variants emerging around the world, should continue to be monitored.”

Thankfully, the virus variant likely hasn’t spread significantly beyond US borders, according to the report.
