📌VARIANT update on #MuVariant vs #DeltaVariant— it seems Ecuador #SARSCoV2 sequencing shows Mu variant competing well versus the Delta variant—both displacing all others. Lambda and Iota almost extinct. ➡️#MuVariant hanging on & expanding next to Delta.🧵

2) That said, in Colombia, where #MuVariant first emerged & once dominant, #DeltaVariant is outpacing Mu. Interesting Ecuador they are more or less tied, but in Columbia Delta is winning. Maybe because immunity against Mu has been building longer in Colombia—while Delta is new.
3) What about #MuVariant vs #DeltaVariant in the US? It seems Delta is harder to control than Mu. Mu seems to rank second in R(t) — the R at current time — behind Delta. This is I guess good. But as Delta goes away, and we lift restrictions- will R(t) of Mu stay under 1? Dunno.
“The #DeltaVariant will not be the last variant of concern (VOC)”, says @WHO’s @mvankerkhove, who warns “The #MuVariant, there are others that are circulating. The surge of not only preparing vaccination, but improving our surveillance systems, getting tests out there”… 🧵
2) “make sure we manage mass gatherings, or postpone them 👀, make sure we fix ventilation in our buildings…” - thank you @mvankerkhove
3) Here is the latest info on the #MuVariant for those interested. I give a more nuanced assessment of it. It could be bad but could be less aggressive than #DeltaVariant, which is still the heavyweight dominant champion variant worldwide currently. See thread 🧵 below ⬇️
📍Bad news on #MuVariant—Japanese scientists: "Mu variant is highly resistant to sera from convalescent & [Pfizer]-vaccinated people. Direct comparison of different spike proteins revealed that Mu spike is more resistant…than all other current variants”🧵

2) The #MuVariant started in Colombia 🇨🇴, but is already worldwide, including in US and UK. In Colombia, how fast did it dominate? Pretty fast. But #DeltaVariant is catch up with it too.
3) Where is it in UK? Popped up everywhere despite Delta domination. Hmm. the-sun.com/health/3614819…
📍The @WHO is monitoring a new coronavirus variant called "mu." It has mutations that have the “potential to evade immunity” by a previous infection or vaccination, the WHO said. #MuVariant was first identified in Colombia & now in at least 39 countries 🧵

2) The new #MuVariant is also known as #B1621 and is currently a new “variant of interest”, but not yet a VOC. who.int/en/activities/…
3) “The variant contains genetic mutations that indicate natural immunity, current vaccines or monoclonal antibody treatments may not work as well against it as they do against the original ancestral virus, the WHO said.”

Neuropathologic evidence strongly suggests that the pathophysiology of COVID-19 related respiratory failure includes a neurogenic component.
