covid 19 mutated into 30 strains
Viruses constantly change through mutation and sometimes these mutations result in a new variant of the virus.
Some changes and mutations allow the virus to spread more easily or make it resistant to treatments or vaccines.
As the virus spreads, it may change and become harder to stop.
How does COVID create new variants?
Coronaviruses like SARS-CoV-2—the virus responsible for COVID-19—use RNA to store their genetic information, and copying RNA is more prone to mistakes than copying DNA.
Researchers have shown that when a coronavirus replicates, around 3 percent of its copies contain a new random error, also known as a mutation.
What were the COVID mutations?
From the genetic sequencing of many virus samples from infected individuals discovered that Gamma variant has accumulated over 22 mutations with about 12 mutations on spike protein.
RBD mutations include: L18F, N501Y, E484K and K 417T.
NTD mutations are also discovered in gamma variant.
What's the new strain of Covid called?
Most recently a strain called JN.1 moved swiftly to become the most widely circulating variant in the United States, accounting for an estimated 83% to 88% of all circulating variants toward the end of January.
