From the CNN-link ; "In late January of 2021, our two independent SARS-CoV-2 genomic surveillance programs, based at the University of New Mexico Health Sciences in Albuquerque, New Mexico and the Louisiana State University Health Sciences Center in Shreveport, Louisiana, each noticed increasing numbers of ... viruses carrying an S:Q677P mutation, and that this variant had increased in frequency in samples collected in late 2020 to mid-January," the researchers wrote. That shorthand -- Q677P-- refers to the specific change in the amino acid making up that part of the spike protein. They've identified seven similar mutations at 677 -- each one appearing to have arisen independently. They named them after birds to make it easier to identify them. One, called Robin 1, has turned up in more than 30 US states, predominating in the Midwest, they said. A second "first appeared from a Oct 6, 2020 sample from Alabama and is named 'Robin 2' owing to its similarity to the parental Robin 1 sub-lineage," they wrote. It's mainly seen in the Southeast. One called Pelican was first seen in a sample from Oregon, and has since turned up in 12 other states as well as Australia, Denmark, Switzerland and India. DJ-With the very limited sequencing the US does some changes showed up more often then others-lots of smaller changes proberbly only showed up in very limited numbers. The Q to P change at position 677 from august 2020 till january 2021 did show up (in seven different forms of combination with other mutations) over 2000 times that it is developing into more of a variant...(or 7 variations of the variant..) New variants should be expected with the extreme large number of infections Covid19 could make in many hosts (mainly humans, minks, cat-likes). We are only seeing the top/start of variations-much more on its way... At the end variations will change Covid19 into a much milder illness-more a cold...for now it may be getting more dangerous..
