India is witnessing a resurgence in COVID-19 cases attributed to the JN.1 variant, leading to concerns about symptoms, safety, and necessary precautions.
The rise in cases is driven by the new subvariant JN.1, along with its descendants LF.7 and NB.1.8, all related to the Omicron lineage. These variants are efficient at spreading, but most cases result in relatively low severity of illness.
The JN.1 variant, originating in the US in September 2023, is classified as a 'variant of interest' by WHO, with symptoms ranging from common cold-like to gastrointestinal issues. Immunity from previous infections or vaccines is waning, contributing to the rise in cases.
While vigilance is essential, there is no need for alarm. Individuals with certain health conditions need to be more cautious. Vaccination, particularly booster shots, is still considered the best protection against the virus.
