Covid-19 cases rising: Is JN.1 variant more deadly and are existing vaccines effective?

Asia is witnessing a fresh surge in COVID-19 cases, with India reporting 257 active cases, primarily in Kerala, Maharashtra, and Tamil Nadu. The rise is linked to the JN.1 variant and its subvariants LF.7 and NB.1.8, known for high transmissibility. JN.1, a descendant of Omicron, carries multiple mutations that help it evade immunity. While symptoms are mostly mild—like sore throat, cough, and fatigue—India remains vigilant. Experts stress that updated vaccines still offer protection against severe illness. The situation is under control but monitored closely.
