The first confirmed variant of Covid in Japan was found in a nursing home in Kentucky, where 45 residents captured Covid.
Dr. William Hasertin, a former Harvard Medical School professor, said the outbreak suggests that the mutant strain (called R.1) is “notable.”
However, the outbreak appears to have been reported by the CDC in April, and data suggest that the mutant strain is now almost gone in the United States.
Professor Christina Pagel of University College London today said the variant does not appear to be a “major threat” and does not surpass Delta.
Professor Lawrence Young, a virologist at Warwick Medical School in the United Kingdom, reiterated her words, saying there were no signs that Delta had been expelled.
Dr. Hasertin told Forbes:
“In addition to some mutations in the peplomer that are common to mutant strains of particular concern, R.1 has a series of unique mutations that may provide additional benefits for transmission, replication, and immunosuppression. I have.”
In the United States, there have been 2,000 cases so far, the last of which was detected in early August.
It accounted for about 1% of infectious diseases in the country in April, but dropped to almost 0% in July as Delta variants became widespread.
There are 20 cases in the UK, the last of which was discovered 4 months ago.
Neither the US Centers for Disease Control and Prevention (CDC) nor the UK-based UK Public Health Center lists any variants of concern or under investigation.
The graph above shows the percentage of Covid infections that have been the R.1 variant in the United States since April last year. This shows that in April the variant was behind 1% of cases, which is now down to 0%.

Covid variant R.1 was first discovered by Japanese scientists in February.
To date, it has caused more than 10,000 infections and has spread to 37 countries. However, it was last discovered over a month ago.
Mutants have mutations that may allow scientists to evade the vaccine, including E484K, which is also found in South African “beta” mutants.
It is also believed to be more contagious than the original virus because it has the mutation found in the British “alpha” mutant.
Professor Pagel, director of clinical operations research at the University College London, said the variant did not appear to be a concern.
She told MailOnline:
Professor Young told MailOnline that it is important to pay attention to all new variants of SARS-CoV-2, the virus behind Covid.
But he added: ‘Delta now seems to outperform all other variants. The delta may have reached its peak transmittance.
“Currently, Delta dominates South Africa, overtaking vaccine-resistant beta variants.”
Outbreaks of the R.1 variant in Kentucky care homes were reported by the CDC and the Kentucky Department of Public Health in April.
They said 46 residents tested positive for the virus, 22 of whom were double vaccinated against Covid.
The report added that vaccinated people who caught Covid were 87 percent less likely to experience symptoms than those who were not jabed.
It comes after the FDA approves a booster vaccine for adults over the age of 65 and other vulnerable groups.
The agency said concerns about infectious delta mutants meant that shots needed to be deployed.
They are available to anyone who received the last dose at least 6 months ago.
