Singapore’s flu positivity rate jumped in just one week, prompting Singaporeans to take precautions

Singapore has observed a surge in flu activity over the past weeks, with the Communicable Disease Control Authority (CDA) reporting that the positivity rate of influenza virus in community influenza-like illness samples climbed to 36.6% during the week of August 16-22. This marks a 24% increase from the previous week, though it remains significantly lower than the January 2025 peak of 43.9%. The CDA reassured the public that the current wave of influenza infections is not more severe than usual.

The 36.6% figure refers to samples from community residents presenting with flu-like symptoms and testing positive for the influenza virus, not the infection rate of the entire population, according to Yan.sg. Flu viruses are present year-round in Singapore, with peak periods typically occurring from May to August and December to March of the following year, making the recent uptick in flu activity expected.

Authorities advise individuals at risk of severe complications from influenza to receive an annual flu vaccine, including those aged 65 and older, children aged 6 months to under 5 years, and others with pre-existing medical conditions. Singapore citizens can obtain free flu vaccines through the HealthSG program, and all children under 5 years old qualify.

For travelers, particularly those planning for the September school holidays, it is recommended to stay informed about the local flu situation and take necessary precautions to minimize risk.

If individuals experience symptoms of a respiratory infection, such as fever and cough, it is advised to limit contact with others, stay indoors, and seek professional medical assistance if needed.
