MOSCOW, March 24. /TASS/. The Vektor State Research Center for Virology and Biotechnology of Russia’s sanitary watchdog Rospotrebnadzor is studying a new isolate of the Southern African strain of SARS-CoV-2, the federal agency said on its website on Wednesday.

"Specialists of Rospotrebnadzor’s Vektor center have obtained a new isolate of SARS-CoV-2, which is related to the Southern African variant, the B.1.351 genetic line," Rospotrebnadzor said in a statement.

Apart from mutations typical for the Southern African strain, the new isolate carries "two additional deletions in genes ORF1ab and S."
