Scientists at the Global Health Research Complex at Texas A & M University have detected a new Covid-19 variant that causes more serious illness and shows signs of a more contagious strain that appears to be resistant to antibodies. Stated.

A new variant, BV-1, named after the origin of the Brazos Valley, was discovered during regular coronavirus screening in Texas A & M via saliva samples from young students with mild cold-like symptoms. .. Students tested positive for Covid on March 5, and tested positive again on March 25. This indicates that new strains can cause longer infections in younger people. The student’s symptoms were resolved by April 2nd, and the third test on April 9th ​​returned negative.

Texas A & M scientists said cell culture-based experiments from other laboratories were ineffective in controlling other mutants with the same genetic markers as BV-1 by some neutralizing antibodies Is said to have shown.

“At this time, the full significance of this mutation is unknown, but there are mutation combinations similar to other internationally noticeable mutations of concern,” said Ben Neumann, chief virologist at Texas A & M. Stated. “This mutant combines genetic markers that are individually associated with rapid spread, serious disease, and high resistance to neutralizing antibodies.”

Scientists also said they submitted a treatise on BV-1 to the Centers for Disease Control and Prevention in Atlanta, warning authorities before further dissemination continued.

The lab has identified many Covid mutations through its sequencing program, but Neuman said the genetic makeup of this strain is of particular concern.

“No more instances of this variant have been detected,” Neuman added. “We have not propagated or tested this virus. This announcement is based purely on laboratory sequence analysis.”

While many US labs sequence only severe Covid cases, Texas A & M Labs test and sequence asymptomatic students to prematurely dangerous strains before causing serious illness. I have found it in.

“Sequencing helps provide an early warning system for new variants,” Neuman said. Laboratory scientists say they do not yet understand the full importance of BV-1, but this variant is “strict, especially among young adults with asymptomatic or mild symptoms. It emphasizes the important need for surveillance and genomic testing. “

Laboratory scientists say the new variant is associated with the British strain B.1.1.7, demonstrating that current vaccines are effective.Related UK strains account for the majority of U.S. subspecies infections
