Dr. Anthony Fauci on Thursday said U.S. public health officials are “keeping a very close eye” on a new variant of Covid-19 that was first detected in Colombia.
Known as B.1.621 or the “Mu variant” according to the World Health Organization nomenclature, it has “a constellation of mutations that indicate potential properties of immune escape,” according to a WHO report released on Monday. “Preliminary data presented to the Virus Evolution Working Group show a reduction in neutralization capacity of convalescent and vaccine era similar to that seen for the Beta variant, but this needs to be confirmed by further studies.”
