Anna Cherkashina, head of the scientific group for genetic engineering and biotechnology at the Central Research Institute of Epidemiology of Rospotrebnadzor, said that all test systems used in Russia are capable of detecting coronavirus, regardless of which version of the virus a person is infected with. It is reported by RIA Novosti.

“All PCR test systems can detect coronavirus in order to establish a diagnosis of COVID-19, regardless of which strain a person has become infected with: delta or omicron. They are focused on that part of the SARS-CoV-2 coronavirus genome that does not undergo such frequent changes and remains almost constant,” Cherkashina said.

She noted that it is necessary, from the point of view of epidemiology, to differentiate “omicron” from “delta” in order to control the development of the epidemiological process and assess the likelihood of a complication of the situation and predict the possible burden on medical institutions.

Previously Director of the Center Gamalei Alexander Gintsburg said that a PCR test after using a nasal coronavirus vaccine could show a positive result, but the likelihood of this is small, since the virus on the mucous membrane is destroyed very quickly.
