On December 8, the new JN.1 variant of COVID-19 was identified in Karakulam, Thiruvananthapuram district of Kerala. This variant, a descendant of the Pirola variant, has been making headlines since its detection in the United States and China.
The JN.1 Variant in Kerala:
The JN.1 variant, traced back to Pirola and BA.2.86, surfaced in Karakulam, Kerala, in a case identified on December 8. The affected individual, a 79-year-old woman, experienced mild symptoms categorized as Influenza Like Illness (ILI) and has since recovered. With only a single mutation in the spike protein compared to its predecessors, JN.1 exhibits high transmissibility, emphasizing the need for preventive measures despite the mild symptoms it presents.

Understanding the JN.1 Strain:
Dr. Tushar Tayal, Lead Consultant in Internal Medicine at CK Birla Hospital, Gurugram, explains that JN.1, first discovered in the USA in September, shares similarities with previous Omicron strains. It is crucial to note that the spike protein mutation, responsible for increased infectivity and potential immune evasion, is a distinctive feature of JN.1. However, Dr. Tayal reassures that existing vaccines targeting the spike protein should remain effective against this variant.
