A new COVID-19 variant called B.1621 or mu is being monitored by scientists by the World Health Organization. While this variant is making news, it’s not the dominant strain in the United States or elsewhere, says Dr. John Oholo, a Mayo Clinic infectious disease doctor.
“Delta variants are actually the predominant strain everywhere at this point. It’s important for scientists and public health officials to pay attention to this, but we’re still not concerned about mu variants and look to the future. I’m in the same place. “
The highly infectious delta variant is twice as contagious as the previous variant. It was first confirmed in India in December 2020. Mu was first detected in Colombia in January 2021. Since the beginning of the pandemic, mutations in SARS-CoV-2, the virus that causes COVID-19, have emerged.
“Each of these variants is partly part of the number of mutations around the virus itself and some of these viral mutations around what is called the spike protein that is actually used to enter the cell and cause infection. It is categorized based on the target, “says Dr. Ohoro. “And it is also the target of many vaccines.”
“The more these change from their original state, the greater the concern that they may evade part of the immune system around the peplomer. In the delta variant, the vaccine is associated with this and is hospitalized or severe. We still see that we can neutralize this at a level sufficient to prevent the infection of the mu variant. Looking at things like mu variants, the unanswered concern and question is how much of these are flowing in. . “
SARS-CoV-2 mutants are divided into three categories based on their ease of spread, severity of symptoms, and treatment.
• Mutant strain of interest
• Variant of concern
• Significant impact variations
Dr. Ohoro describes this category as “the threat board that some scientists use to track these variants.” They are investigating which of these actually causes serious illness and is increasing infections like Delta. These are mutant strains of concern as they have the potential to spread and have been recorded in more regions. Watch carefully like Mu — it’s a variant of concern. And variants that appear where there are more hypothetical concerns about them, but worth paying attention to, will be the variants of interest. “
Vaccination continues to be the most important step in preventing serious illness caused by COVID-19 infection. It takes at least two weeks after receiving the vaccine to be fully effective.
“Vaccination against mutants is still very effective. Although there are reports of breakthrough cases, they tend to be much less severe and less frequent. National vaccination rates It turns out that high areas are less affected by the delta variant, which not only keeps hospitals and clinics from being overwhelmed, but also helps keep individuals safe.
