COVID-19 cases rise in Asia as JN.1 variant spreads — Here's what you need to know
A new wave of COVID-19 infections is sweeping across parts of Asia, mainly fueled by the fast-spreading JN.1 variant of the Omicron strain. Countries like Thailand, Hong Kong, and Singapore are reporting a sharp rise in cases, while India is seeing a milder increase.
What’s Happening?
Since January 2025, Thailand has logged over 71,000 COVID-19 cases.
Hong Kong has reported 1,042 cases and 31 deaths, the highest toll in a year.
Singapore has seen around 14,200 cases, with hospitalizations up by 30%.
India’s Situation
India is witnessing a slight uptick in cases, but health authorities say the situation is under control. Surveillance and preparedness are being strengthened.
What is JN.1?
JN.1 is a subvariant of Omicron BA.2.86, first identified in late 2023.
It carries about 30 mutations, making it more transmissible.
It has been detected in the US, UK, India, Singapore, and Hong Kong.
In December 2023, the World Health Organization (WHO) classified JN.1 as a “variant of interest”, meaning it is being closely monitored but is not currently linked to severe illness.
Symptoms to Watch Out For
Most JN.1 infections are mild to moderate, with symptoms like:
Sore throat
Cough
Fever
Fatigue
Runny nose
In some cases: conjunctivitis, diarrhea, or mild stomach discomfort
Are Vaccines Still Effective?
Yes. Updated mRNA vaccines (bivalent and monovalent boosters) are still effective in preventing severe disease, hospitalizations, and death. However, they might be less effective against mild or asymptomatic infections.
What Precautions Should You Take?
Health experts recommend continuing basic COVID-19 precautions:
Wear masks in crowded or poorly ventilated places
Wash hands frequently
Avoid close contact with people showing symptoms
Stay updated on vaccines and booster doses
Seek medical help if you’re in a high-risk group or develop symptoms
As new variants emerge, staying informed and cautious remains key to keeping yourself and your community safe.
