The virus strain, originally from Japan, is known as R.1 and contains dangerous mutations that improve its “transmission, reproduction, and immunosuppression,” according to the US magazine Forbes. “R.1 is a variant that needs to be looked at in more detail. It has established itself in Japan and the USA,” Author and infectious disease expert William A. Haseltine.
According to the English Daily Mail, variants of the R.1 SARS-CoV-2 pathogen share, among other things, a mutation in the so-called spike protein, which has also been identified in highly contagious (such as delta) variants of coronavirus. From Brazil, UK, India and South Africa.

However, the R.1 variant, which entered a Kentucky nursing home, is not considered particularly worrisome, author Haseltine writes. Although one of several mutations called D614G is associated with “increased virus transmission” and another called W152L may reduce the effectiveness of neutralizing coronavirus antibodies.
The good news is that most Kentucky nursing home residents who have tested positive for the virus have not shown symptoms. Nor was there, apparently thanks to vaccination, a difficult path to disease or death.
