COVID-19 Surge in Asia 2025: Should Summer Travelers Be Concerned?
New Delhi, May 28 — As summer approaches, a familiar threat is resurfacing across Asia. COVID-19 infections are on the rise again, with several countries, including Singapore, Hong Kong, Thailand, and India, reporting noticeable spikes in cases. The emergence of fast-spreading Omicron sub-variants—JN.1, NB.1.8.1, LF.7, and XFG—is raising new public health concerns, although no major restrictions have been reimposed.
Rising Numbers Across the Region
According to Singapore’s Ministry of Health, weekly COVID-19 cases have exceeded 14,000 as of mid-May. Hong Kong has also seen its positivity rate climb from 1.7% in March to over 11% this month.
In Thailand, clusters have emerged in Bangkok, Chon Buri, and Samut Prakan following April’s Songkran festival. Meanwhile, India crossed the 1,000 active case mark on Monday, with Kerala (430 cases), Maharashtra (210), and Delhi (104) reporting the highest numbers, according to the Ministry of Health.
Despite the increase, most infections remain mild and manageable without hospitalization, health authorities said.
The Variants Driving the Surge
The primary culprits are four Omicron sub-variants—JN.1, NB.1.8.1, LF.7, and XFG. Of these, JN.1, LF.7, and NB.1.8.1 are the most prevalent across South and Southeast Asia.
The World Health Organization (WHO) has not declared these sub-variants as “Variants of Concern” but has categorized NB.1.8 and LF.7 as “Variants Under Monitoring.” Experts remain cautious as the characteristics and transmissibility of these strains are still being studied.
Can I Still Travel?
Yes. Currently, no country in the region has closed its borders or introduced new entry restrictions. Airlines are operating normally, and international and domestic travel within India remains uninterrupted.
