As of late, it appears as if you cannot scan the information with out seeing a COVID-19-related headline. And whereas the highly contagious Delta variant remains to be very a lot on everybody’s radar, it appears there’s one other variant that international well being consultants are monitoring. (Associated: What Is the C.1.2 COVID-19 Variant?)
The B.1.621 variant, higher often called Mu, has been positioned on the World Well being Group’s checklist of SARS-CoV-2 variants of interest, that are variants “with genetic modifications which might be predicted to have an effect on virus traits,” corresponding to transmissibility and illness severity, amongst different elements. As of Monday, August 30, the WHO is carefully monitoring the unfold of Mu. Though developments about Mu are nonetheless ongoing, here is a breakdown of what is at the moment identified concerning the variant. (ICYMI: How Effective Is the COVID-19 Vaccine?)
When and The place Did the Mu Variant Originate?
The Mu variant was first recognized by means of genomic sequencing (the method utilized by scientists to research viral strains) in Colombia again in January. It at the moment accounts for about 40 p.c of instances within the nation, in line with a latest weekly bulletin from the WHO. Although different instances have been reported elsewhere (together with South America, Europe, and the U.S., in line with The Guardian), Vivek Cherian, M.D., an inner medication doctor affiliated with the College of Maryland Medical System, tells Form it is too early to unnecessarily fear about Mu. “It is regarding that the prevalence of the variant in Colombia is persistently rising, although the worldwide prevalence is definitely beneath 0.1 p.c,” he tells Form.

Is the Mu Variant Harmful?
With Mu at the moment listed as certainly one of WHO’s variants of curiosity, it is comprehensible when you really feel unsettled. But it surely’s additionally value noting that, as of now, the Facilities for Illness Management and Prevention has not listed Mu below its variants of interest or variants of concern (which embody variants, such as Delta, which have proof of elevated transmissibility, extra extreme illness, and diminished effectiveness in vaccines).
As for Mu’s make-up, the WHO notes that the variant “has a constellation of mutations that point out potential properties of immune escape.” Which means the immunity you at the moment have (both obtained through a vaccine or pure immunity after having the virus) might not be as efficient in comparison with earlier strains or the unique SARS-CoV-2 virus (the Alpha variant), attributable to genetic mutations recognized on this explicit pressure, says Dr. Cherian. Monoclonal antibody treatments, that are used to mild-to-moderate COVID-19, might also be much less efficient towards the Mu variant, he says. “All of that is based mostly on a assessment of preliminary data which confirmed diminished effectiveness of antibodies obtained from vaccination or prior publicity.” (Learn extra: Why Are the New COVID-19 Strains Spreading More Quickly?)
As for Mu’s severity and contagiousness? The WHO is “nonetheless within the technique of gathering extra knowledge, which is able to decide the variant’s potential to trigger extra extreme illness, be extra transmissible or have diminished effectiveness of remedies or vaccines, which is the present concern” in line with Dr. Cherian. Given how fast the Delta variant rose across the globe, “there is definitely an opportunity [Mu] may be upgraded to a variant of concern,” he says.
Nonetheless, he reiterates that “finally, all that is based mostly on early data, and extra time and knowledge is required to make any definitive assertion concerning the Mu variant.” It is too early to inform if Mu will grow to be a very worrisome variant for totally vaccinated People. “You’ll be able to’t make any generalizations from the truth that Mu is listed as a variant of curiosity,” he says.
What to Do About Mu
“A virus’s potential to grow to be dominant finally is dependent upon two main elements: how transmissible/contagious the pressure is and the way efficient it’s at inflicting extreme illness and or dying,” says Dr. Cherian. “Virus mutations are continuously occurring, and finally any mutation(s) that trigger a selected pressure to be extra contagious or extra deadly (or worse, each), are extra seemingly going to have the next likelihood of changing into dominant.”
Proper now, the perfect traces of protection embody wearing masks in public and indoors when not with folks out of your family, completing your vaccination doses, and getting a booster shot if you’re eligible (i.e. eight months after your second vaccine dose for Pfizer-BioNTech or Moderna recipients, in line with the CDC). These are amongst a number of the simplest instruments that will help you preserve COVID-19 and all its variants at bay. (FYI: Johnson &Johnson hive, your booster recs are on the way soon.)
The knowledge on this story is correct as of press time. As updates about coronavirus COVID-19 proceed to evolve, it is attainable that some data and suggestions on this story have modified since preliminary publication. We encourage you to test in frequently with sources such because the CDC, the WHO, and your native public well being division for probably the most up-to-date knowledge and suggestions.
