Health authorities monitor rising flu activity while hospitals report no unusual increase in severe infections.
Singapore is seeing a notable rise in influenza cases, prompting health authorities to closely monitor the situation. Despite the increase, the Communicable Diseases Agency (CDA) says there are currently no indications that infections are causing more severe illness than typically expected from seasonal flu.
Influenza Cases Climb in Singapore
Singapore has recorded an increase in influenza activity, with the positivity rate among influenza-like illness samples in the community rising to 36.6 percent in the week of August 16 to 22, from 24.0 percent the previous week. Infectious diseases specialist Leong Hoe Nam identified H3N2 as the strain currently circulating and advised vulnerable groups to remain up to date with influenza vaccination.
No Evidence of More Severe Infections
Despite the increase in influenza activity, the CDA said there are currently no indications that infections are more severe than usual. CDA said it is continuing to monitor the situation as influenza activity increases.
Increase Follows Regional Flu Activity
Seasonal influenza viruses circulate throughout the year in Singapore, with higher levels of activity typically seen from May to August and from December to March.

Vaccination Recommended for Higher-Risk Groups
Health authorities continue to encourage influenza vaccination, particularly for people at greater risk of complications. These include children aged six months to four years, adults aged 65 and above, pregnant women, and people with certain chronic medical conditions. Vaccination does not eliminate every infection but can reduce the likelihood of serious influenza-related complications.
Public Urged to Take Basic Precautions
People with mild respiratory symptoms are advised to stay home until their symptoms resolve and, if they need to go out, minimize social interactions, wear a mask and avoid crowded places or contact with medically vulnerable people. Seeking medical attention is recommended when symptoms become severe or when someone belongs to a higher-risk group. With frequent travel between Singapore and neighboring countries, monitoring respiratory infections also remains important beyond the city-state itself.
Singapore’s influenza increase warrants attention, but current evidence does not suggest that the circulating infections are unusually severe. For Singaporeans, vaccination and basic precautions remain important, particularly among vulnerable groups. For Indonesians, especially residents of Batam and the Riau Islands who frequently travel to Singapore, awareness of increased flu activity can help reduce transmission across one of Southeast Asia’s busiest cross-border travel corridors.
