Noida: COVID-19 has once again made its presence felt in India, with fresh cases emerging in Noida and a steady uptick recorded in metro cities like Delhi and Mumbai. The resurgence of cases across Asia — particularly in Singapore, China, Thailand, Hong Kong, and now India — has raised public concerns about whether a booster dose might be required once more.
COVID-19 Cases Rising in Asia
In the first half of May 2025, Singapore reported over 14,000 new cases, marking a 28% increase compared to the same period last year. Hong Kong has witnessed a 30-fold spike in infections over 10 weeks. In China, the test positivity rate has doubled. Thailand also saw a rise in cases following the April Songkran festival.
India, though still reporting relatively low numbers, had 257 active cases as of May 19, 2025. These cases are concentrated primarily in Kerala, Maharashtra, and Tamil Nadu.
The Variant Behind the Surge
The resurgence is being attributed to the Omicron subvariant JN.1 and its offshoots LF.7 and NB.1.8. In December 2023, the World Health Organization (WHO) categorized JN.1 as a “variant of interest.” While highly transmissible, experts say it is not more severe than previous variants. Symptoms have mostly been mild, such as fever, cough, sore throat, and body ache.
Current Situation in India
According to health experts, there is no reason to panic. India’s case count remains minimal in comparison to its large population, and most infections are mild. Hospitalizations are rare, and the Health Ministry has clarified that no new COVID wave has been detected, though it has advised continued vigilance and precaution.
Should You Take a Booster Dose?
The big question on many minds: Is another booster shot necessary?
Doctors suggest that immunocompromised individuals, senior citizens, children, and those with chronic illnesses like diabetes or cancer should consider taking a booster dose. In Hong Kong and Singapore, health authorities are already recommending booster shots for individuals whose last vaccine or infection occurred over six months ago.
In India, a booster dose may also be a wise choice for travelers heading to countries with rising COVID-19 numbers. According to the WHO, the XBB.1.5 monovalent booster vaccine can offer 19% to 49% protection against the JN.1 variant.
What Should You Do Now?
If you’re healthy and have been fully vaccinated, there’s no need to panic. However, maintaining COVID-appropriate behavior, including masking in crowded places, hand hygiene, and monitoring for symptoms, remains important.
The situation continues to evolve, but for now, India appears to be in control — provided citizens remain cautious and well-informed.
