The World Well being Group (WHO) has designated the Mu variant of SARS-CoV-2 as a “Variant of Curiosity,” spreading to 49 U.S. states and 46 international locations.
The Mu variant was first recognized in Colombia in January, and makes up practically 40% of instances there, in response to the WHO.
There are over 2,100 instances of Mu within the U.S., and it has unfold to 49 states, with Nebraska being the one one which hasn’t recorded it, in response to Outbreak.information, which is an information aggregation web site that’s maintained by three Scripps Analysis labs. Mu accounts for 4 p.c of instances in Alaska, at 147. California has the very best quantity of Mu instances within the U.S., reporting 399, with Florida following at 305 instances, and New York at 203.
Some mutations present in Mu are per the Alpha, Beta, and Delta variants, together with elevated transmissibility and linkage to immune escape, in response to Public Well being England.
Whereas detailed research of the variant traits of Mu haven’t been carried out but, preliminary information given to the WHO’s Virus Evolution Working Group reveals that it reveals an escape of immune safety from vaccines just like the Beta variant, UN Information reported.
Paúl Cárdenas, an infectious illness researcher with Universidad San Francisco de Quito in Ecuador, informed The Washington Submit that based mostly on his research of Mu, it’s “extra transmissible” than the unique SARS-CoV-2, and has “been capable of outcompete gamma and alpha in most components of Ecuador and Colombia.”
Pfizer spokesperson Package Longley remained optimistic, telling The Submit in an e mail that the corporate is finding out Mu and plans on sharing its information with a peer-reviewed journal quickly. “To this point, we’re inspired by each the real-world information and laboratory research of the vaccine and see no proof that the virus or circulating variants of concern often escape safety,” she stated.
