LAFAYETTE, La. (KADN) — There's a new COVID variant making people sick. It's called JN.1. But how does it compare to other COVID strains?
This latest virus is part of the SARS COVID-2 BA2.86 family, which has quite an impressive family tree. So, why has this strain taken off? And does it pose a significant threat?
To answer this, let's look at the coronavirus. Our immune system is looking for one of three proteins on its surface. These are called the E, S, and M. As this virus mutates over time, these proteins change. With a big enough change, we get another branch in the family tree and it becomes harder for our immune system to react to this new branch.
And that really fits what we're seeing. This new JN.1 branch is fairly contagious and rapidly is becoming a dominant strain.
(CNN) — The US Centers for Disease Control and Prevention estimates that the coronavirus subvariant JN.1 is now causing about 20% of new Covid…
Now, always the main concern is that one day there will be a big mutation. If that occurs, the virus can completely hide from our immune system and we face another aggressive pandemic like the original COVID.
However, for now, 97% of the US population has antibodies to the original SARS COVID-2 and that likely offers protection against significant illness.
So, while this new JN.1 branch may be more contagious, symptoms are more likely to be mild and we should have some protection against serious illness.
