Asia is witnessing a renewed spike in COVID-19 cases, largely attributed to the fast-spreading JN.1 variant, a descendant of the Omicron BA.2.86 lineage. Though global health experts maintain the strain causes mild illness in most cases, public health authorities across the region are ramping up surveillance and urging caution.
India Sees Gradual Rise
As of May 19, 2025, India reported 257 active COVID-19 cases. The southern state of Kerala leads with 69 cases, followed by Maharashtra (44) and Tamil Nadu (34). While the situation remains under control, health officials attribute the uptick to high humidity and increased international travel. (zeenews.india.com)

What is the JN.1 Variant?
First identified in the United States in September 2023, JN.1 is part of the Omicron family. According to the World Health Organization, it is currently classified as a “variant of interest.”
Common symptoms include:
- Fever
- Cough
- Fatigue
- Diarrhea
- Mild respiratory issues
Studies so far show that JN.1 does not cause more severe illness compared to previous variants, but its high transmissibility is a concern for healthcare systems.
Precautions and Public Advice
Health authorities across Asia are urging people to:
- Get vaccinated and boosted if eligible
- Wear masks in crowded places
- Maintain hand hygiene and social distancing
- Monitor travel-related symptoms, especially when returning from areas with known outbreaks
Countries including India, Thailand, and Singapore have heightened airport screenings and increased public awareness efforts in response to the variant.
