JN.1 is actually a subvariant of the Omicron, evolving from the BA.2.86 variant, also known as Pirola. It was first identified in Luxembourg in 2023 and since has gradually spread to other parts of the world, and now India. JN.1 is said to be more transmissible than previous variants due to specific mutations in its spike protein, which helps it binds to humans easily. However, as of now, there is no data to prove that it causes any serious illness.
