A fresh wave of Covid-19 infections sweeping across Asia is prompting renewed caution among travelers and governments alike, as countries like Singapore, Hong Kong, Thailand, and China report significant spikes in cases. This resurgence, driven by waning immunity and new variants, is casting a shadow over the region’s booming travel industry, which had been rebounding strongly post-pandemic.
Surge in Cases Prompts Travel Concerns
Health authorities in Singapore reported a 28% increase in Covid-19 cases for the week ending May 3, with an estimated 14,200 infections, up from 11,100 the previous week. Hospitalizations rose by 30%, though intensive care unit cases remained stable. In Hong Kong, the positivity rate for Covid-19 in respiratory samples hit a one-year high of 13.66% in the week ending May 10, with 1,042 cases reported, a sharp rise from 33 cases weekly in early March. Thailand noted a surge following its Songkran festival in April, with 71,067 infections and 19 deaths recorded between January 1 and May 14, 2025. China is also bracing for a wave potentially matching last summer’s peak, with test positivity rates doubling in recent weeks.
The rise is largely attributed to the JN.1 variant and its sub-lineages, LF.7 and NB.1.8, which account for over two-thirds of cases in Singapore. While these variants are not deemed more severe, waning immunity—particularly among those who haven’t received booster shots in over a year—has fueled the spread. Health officials across the region emphasize that the virus, now considered endemic, exhibits periodic surges, defying earlier assumptions of seasonal patterns by spreading even in warmer months.
Impact on Travel
The resurgence has led to heightened vigilance and new measures affecting travel. Nepal, for instance, has scaled up surveillance at border points and Tribhuvan International Airport, targeting travelers from affected countries like Singapore, Hong Kong, Thailand, and India. Dr. Sher Bahadur Pun, a Nepalese health expert, warned that the virus could easily spread due to geographic proximity and frequent travel, urging stricter monitoring of influenza-like symptoms.
In Thailand, the government has advised mask-wearing and heightened awareness, particularly for the elderly and unvaccinated, following cluster outbreaks linked to large gatherings. While no new lockdowns are planned, Thailand’s bolstered passenger rights regulations aim to mitigate travel disruptions caused by flight cancellations or delays, a move to reassure tourists amid rising cases.
Singapore and Hong Kong, major travel hubs, are urging high-risk groups to get booster shots, with authorities emphasizing personal hygiene and mask-wearing in crowded indoor spaces. Although travel restrictions remain minimal, the surge has prompted some airlines and travelers to reconsider plans. For example, Hong Kong pop star Eason Chan postponed Taiwan concerts after testing positive, signaling how even high-profile travel is affected.
Industry and Traveler Response
The Asia-Pacific travel sector, which had been thriving with a projected 7.9% growth in air travel, faces uncertainty. Singapore’s Changi Airport, a global transit hub, continues to operate normally but with heightened health protocols. Travel platforms like Agoda, which recently launched a major anniversary sale, are monitoring the situation but report no significant cancellations yet. However, travelers are advised to check entry requirements, as some countries may reinstate testing or vaccination checks if cases escalate.
Travelers are also adapting. Social media posts on X reflect growing concern, with users noting the surge’s potential to spread globally and urging caution. One post highlighted Singapore’s case spike and Hong Kong’s high viral load in sewage, suggesting Covid’s seasonal pattern in the region. Another warned of the NB.1.8.1 sub-variant’s dominance in Hong Kong, predicting broader implications.
Looking Ahead
While the current variants are not more virulent, the rise in hospitalizations and deaths—particularly among the elderly—has put health systems on alert. Experts recommend that travelers ensure vaccinations are up to date, carry masks for crowded settings, and monitor local health advisories. The World Health Organization has called for strengthened surveillance and data sharing to track variants like JN.1, emphasizing that Covid-19 remains a global health challenge.
As Asia’s travel industry navigates this new wave, the balance between economic recovery and public health remains delicate. For now, travelers are urged to stay informed and take precautions to ensure safe journeys in a region still grappling with an unpredictable virus.
