Don’t let that confuse you with “delta plus”. The filter is unaware of any new scams.


The name delta, meanwhile, comes from the WHO system, meant to simplify genomics for the general public. It provides names of relevant covid samples if it believes they may be of specific interest. There are now eight families with Greek letters, but until there is evidence a new sublineage of the first delta strain behaves differently from its parents, the WHO considers them all delta.

“Delta plus” took the WHO designation and mixed it with Pango’s ancestry information. This does not mean that the virus is more dangerous or more talked about.

“People are excited when they see Pango’s new name. But we should not be angry at the discovery of new varieties. All the time, we see new varieties that are never really different in character, ”Brito said. “If we have evidence that a new lineage pays more, who will give it a new name.”

Tracking evolution

“For a genomic scientist like me, I wanted to know what differences we saw,” said Kelsey Florek, senior genomics and data scientist for the Wisconsin state public health lab. “For most of the public, it really makes no difference. Classifying them all as deltas is enough for communication with policy makers, public health, and the public.”

Basically, viral evolution will act like any other. As the virus spreads in the body, it makes copies of itself, often with small flaws and changes. Most of these are dead, but sometimes, a copy with a mistranslation is enough to fit inside someone to spread to others.

This week, scientists divided the delta’s “children” into 12 families to track small local changes. None of this means that the virus itself suddenly changes.

As the virus spreads from person to person, it accumulates small changes, allowing scientists to follow the patterns of transmission-in the same way we look at human genomes. and identify who the people involved are. But in a virus, most genetic changes have no effect on the way they affect individuals and communities.

Genomic scientists still need a way to track that viral evolution, however, for core science and to detect any behavioral changes as quickly as possible. That’s why they keep a close eye on delta patterns, especially, because it’s so rapidly spreading. The Pango team continues to divide the generations of the first line of the delta, B.1.617.2, into subcategories of relevant cases.

To date, it has registered 617.2 itself plus three “children,” called AY.1, AY.2, and AY.3. This week, the group decided to divide the children into 12 families to keep up with small local changes-so a total of 13 are different in the delta. None of this means that the virus itself suddenly changes.

“Especially on the margins, in the coming seasons, you’re separating hairs,” said Duncan MacCannell, chief science officer at the CDC’s Office of Advanced Molecular Detection. “Depending on how the definitions and refinements are made, hair can part in different ways.”

What is the public cause?

It is worth remembering that not all species with WHO names are equally evil. When the organization names a new family, it also adds a mark that tells us what we need to worry about.

The lowest level is a different in interest, which means it should be guarded; in the middle is a various concerns, such as the delta, which is clearly evolving to be more dangerous. Often, different interests are marked because they share a mutation of different concerns. They were watched.
