The Omicron strain is the most contagious one among all coronavirus variants according to new instructional guidelines on treating and preventing the coronavirus infection by the Russian Health Ministry, APA reports citing TASS.

"The Omicron variant which carries multiple replacements in the S-protein of the coronavirus with half of them located in the receptor-binding domain, possesses the highest contagiousness (transmissibility) among all SARS-CoV-2 variants," according to the document published on the ministry’s website.

It is noted that the widespread Delta and Omicron coronavirus variants carry mutations in their genomes that decrease the recognition of viral antigens by post-infection and post-vaccination antibodies.
