JN.1 variant COVID

India recently reported a case of JN.1 from Kerala, as part of routine surveillance and genome sequencing by INSACOG.

INSACOG is an Indian SARS-CoV-2 Genomics Consortium, a network of genomic laboratories.

JN.1 - It is a descendant of the Pirola variant (BA.2.86), which itself stems from the Omicron sub-variant.
It carries mutations in the spike protein that may increase its infectivity and ability to evade immune responses.

The lineages are assigned by an international network called PANGO. The Pango nomenclature is being used to track the transmission and spread of SARS-CoV-2, including variants of concern.

Continued growth of JN.1 - It is either more transmissible or better at evading our immune systems.
Symptoms - Like other variants, it causes fever, shortness of breath, runny nose, sore throat, cough, fatigue etc.

The B.1.1.529 lineage (Omicron) was the last lineage designated as a Variant of Concern (VOC) by World Health Organisation (WHO).

Treatment - According to Union Health Ministry, the existing line of treatment for Covid-19 is expected to be effective against this variant as well.

Doctors advise targeted vaccination for individuals who may have a compromised immunity system and the elderly, if required.
