The Department of Health (DOH) has reported an approximately 8% increase in influenza-like illness (ILI) cases, with 11,137 cases recorded in its latest monitoring period, prompting preparations for a nationwide flu vaccination rollout beginning the week of October 26. DOH Acting Secretary Edwin Mercado said respiratory infections have become more common as cooler weather and increased social gatherings create conditions that allow illnesses to spread more easily. Despite the recent increase, the department recorded 122,514 cumulative cases in 2026, approximately 20% lower than the 152,972 cases documented during the comparable period last year.
To reduce the risk of severe illness, the DOH plans to prioritize senior citizens, young children, and individuals with underlying medical conditions during its upcoming vaccination campaign, which is expected to continue through December. Influenza-like illnesses can involve symptoms such as fever, cough, sore throat, and body aches, although not every reported case is necessarily caused by the influenza virus. Health authorities emphasized that vaccination remains an important preventive measure, particularly for people who face greater risks of complications from respiratory infections.
The DOH also reminded Filipinos to observe basic preventive measures, including frequent handwashing, proper cough etiquette, wearing a mask when experiencing respiratory symptoms, and staying home when sick to avoid spreading infections. Maintaining good ventilation and avoiding unnecessary close contact with vulnerable individuals can further reduce transmission risks. Although the current increase has not been classified as an epidemic, the department continues monitoring respiratory illness trends ahead of the holiday season, when family gatherings, travel, and crowded public spaces may increase opportunities for infections to spread.
