Current Situation Overview:

Singapore

1) Significant Increase in Cases: The Ministry of Health (MOH) in Singapore reported a substantial rise in COVID-19 cases. In the week of April 27 to May 3, 2025, the estimated number of cases reached 14,200, up from 11,100 the previous week, marking a 28% increase.

2) Hospitalizations Rising: Concurrently, average daily COVID-19 hospitalizations in Singapore also saw an increase, from 102 to 133 during the same period. While hospitals are currently managing the increased caseload, the trend warrants attention. Intensive Care Unit (ICU) cases, however, reportedly decreased from three to two daily.

3) Dominant Variants: The current surge in Singapore is attributed to the circulation of LF.7 and NB.1.8, both sub-lineages of the JN.1 variant. These variants account for over two-thirds of locally sequenced cases. JN.1 is also the variant used in the formulation of the current COVID-19 vaccines.

4) Contributing Factors: Singaporean health authorities point to waning population immunity (many infected individuals hadn't received booster shots in over a year), increased social interactions, seasonal factors, and greater travel as key drivers of the current wave.

5) Expectation of Periodic Waves: Singapore's health ministry has stated that periodic COVID-19 waves are expected throughout the year, indicating that the virus has become endemic with a predictable pattern of activity.

Hong Kong

1) High Virus Activity: Hong Kong's Centre for Health Protection (CHP) has noted that local COVID-19 activity is "quite high." The percentage of respiratory samples testing positive for SARS-CoV-2 has reached its highest level in a year, more than doubling from 6.21% in early April to 13.66% by mid-April.

2) Increase in Severe Cases: The city recorded 31 severe cases in the week ending May 3, which is a 12-month peak.

3) Dominant Variant: The XDV strain, a JN.1-related variant, has been circulating locally in Hong Kong since late March. Previous predominant strains included XBB, JN.1, KP.2, and KP.3 at different points in 2024.

4) Endemic and Cyclical Pattern: Hong Kong's health department believes COVID-19 has evolved into an "endemic disease with a periodic pattern," expecting active cycles every six to nine months due to declining herd immunity and changing variants.

5) Sewage Surveillance: Increased viral concentrations in sewage samples also suggest widespread community transmission.

Key Considerations For Travelers:

1) Increased Risk of Infection: With a rise in cases, the likelihood of contracting COVID-19 in Singapore and Hong Kong is higher. While most cases are reported to be mild and not associated with unusual severity or mortality, individuals may still experience symptoms and potentially spread the virus.

2) Waning Immunity: A significant factor contributing to the surge in both regions is waning population immunity, meaning protection from previous infections or vaccinations may have decreased over time.

3) Vulnerable Populations: Individuals at increased risk of severe COVID-19, such as those aged 60 and above, medically vulnerable individuals, and residents of aged care facilities, are strongly recommended to keep their vaccinations updated, receiving an additional dose around one year after their last dose.

4) Potential for Travel Disruptions: While no widespread travel restrictions are currently in place, a significant increase in cases could lead to unforeseen disruptions, such as stricter entry requirements or changes in local health protocols.

Recommended Precautions:

For those who decide to travel to Singapore or Hong Kong despite the advisory, it is crucial to take proactive measures to protect yourself and others:

1) Vaccination and Boosters: Ensure you are up-to-date with your COVID-19 vaccinations and booster shots. The current vaccines are formulated with variants like JN.1, which is prevalent in both regions, and are effective in preventing severe disease, hospitalization, and death.

2) Mask Wearing: Consider wearing a mask, especially in crowded indoor settings, on public transportation, and in healthcare facilities.

3) Hand Hygiene: Practice frequent hand washing with soap and water or use an alcohol-based hand sanitizer.

4) Avoid Crowded Places: Limit exposure to large gatherings and crowded areas where the risk of transmission is higher.

5) Monitor Health: Be vigilant for any symptoms of COVID-19. If you develop symptoms, seek medical advice and follow local guidelines for testing and isolation.

6) Travel Insurance: Consider obtaining comprehensive travel insurance that covers COVID-19-related medical expenses and potential travel disruptions.

Conclusion

While Singapore and Hong Kong have robust healthcare systems and have transitioned to managing COVID-19 as an endemic disease, the current uptick in cases serves as a reminder that the virus remains a public health consideration. Travelers should carefully assess their personal risk factors, consider the potential for exposure, and implement appropriate precautionary measures to ensure a safe and healthy trip. For non-essential travel, postponing your trip might be a sensible option given the current circumstances.
