China News Service, April 23. According to foreign media reports, WHO statistics show that on the 22nd, there were 874,381 new confirmed cases of new coronary pneumonia worldwide, and the number of new cases in a single day was the highest since the outbreak.

Among them, Europe, America and India became the hardest hit areas.

At the same time, scientists at Texas A&M University in the United States said that a new variant of the new coronavirus has been discovered.

  Scientists from the Global Health Research Center of Texas A&M University (TAMU) said they have discovered a new variant of the new coronavirus. The virus strain is more contagious and more likely to cause severe disease. It seems to be resistant to antibodies.

  The new variant is called BV-1, named after the Brazos Valley where it originated.

This variant was discovered by Texas A&M University during routine screening of a student with mild cold symptoms.

  On March 5, the student tested positive for the new crown. On March 25, the second test was still positive, indicating that the new strain may cause infection for a longer period of time.

On April 2, the student’s related symptoms disappeared, and the third test result on April 9 was negative.

  Scientists at Texas A&M University said that cell culture experiments from other laboratories have shown that several neutralizing antibodies are not effective against other variants that have the same genetic markers as BV-1.

  The university’s chief virologist (Ben Neuman) said: “We do not yet fully understand this variant, but it has a similar combination of mutations with other variants that have attracted international attention. This variant combines with rapid spread, Genetic markers related to severe illness and high resistance to neutralizing antibodies."
