The JN.1 variant of COVID-19, linked to Omicron, is spreading rapidly in Asia, especially Singapore and Hong Kong.
India has also seen cases, with Mumbai reporting two recent COVID-related deaths in patients with other health issues.
Though the virus is considered endemic, concern is growing over fast-spreading subvariants OF.7 and NB.1.8.
These strains belong to the JN.1 lineage and are believed to be more transmissible, contributing to the recent surge in infections.
The World Health Organization has labeled JN.1 a "variant of interest." Immunity from past infections and vaccines is waning, increasing susceptibility.
Singapore has recorded a 28% rise in cases, while Hong Kong’s test positivity rate has more than doubled.
Symptoms of these variants include sore throat, cough, and fever but remain mild in vaccinated individuals. Loss of smell or taste is no longer common.
Authorities recommend vaccination, especially boosters for high-risk groups, and following basic precautions like mask-wearing, hand hygiene, and home isolation when unwell to control the spread.
