New Covid variant Pirola spreading  across the US 




A Yale Medicine Review report says Pirola has “more than 30 mutations to its spike protein compared to XBB.1.5, 

While the report says that it is too early to know if this strain is any more transmissible than other ones, there may be a reason to worry.

Pirola has been witnessed in the US, the UK, and other countries, in unrelated cases.

According to Yale Medicine infectious diseases specialist Scott Roberts, MD, the high number of mutations is a point of concern here

He said in the report that this was similar to the number of mutations that differed between Delta, one of the early strains of the coronavirus, and Omicron

Speaking to the Yale School of Medicine, Anne Hahn, a postdoctoral associate who leads the Yale SARS-CoV-2 Genomic Surveillance Initiative,

What differentiates Pirola?

Said that this is a “much more interesting subvariant”, when compared to the Omicron subvariant known as XBB.1.9.

That variant initially spread quickly but did not overwhelm populations at a significant scale.

The same report noted that it has been detected by surveillance labs in Israel and Denmark and later in labs in England, South Africa, and the United States.
