MANILA, Philippines — The Department of Health (DOH) has reported an 8% increase in influenza-like illness (ILI) cases, prompting preparations for a flu vaccination campaign that will prioritize Filipinos at greater risk of complications.

Acting Health Secretary Edwin Mercado said on Sunday, October 25, that the department recorded 11,137 cases in its latest monitoring period, compared with 10,278 cases reported from September 3 to 16.

Despite the recent increase, Mercado said the overall number of cases recorded this year remains lower than in 2025.

DOH data showed that 122,514 ILI cases have been recorded so far in 2026, approximately 20% below the 152,972 cases reported during the comparable period last year.

Mercado attributed the recent rise partly to cooler weather and increased social gatherings, which can create more opportunities for respiratory infections to spread.

He also warned that upcoming Christmas and New Year celebrations could contribute to further increases as more people gather indoors or in crowded spaces.

To strengthen protection against influenza, the DOH is preparing to distribute flu vaccines beginning the week of October 26.

The vaccination campaign is expected to continue through December, with priority given to senior citizens, young children, and people with underlying medical conditions.

These groups face a greater risk of developing serious complications from influenza.

Earlier, the DOH announced plans to procure more than three million influenza vaccine doses for 2026, with deliveries expected in October or November.

Influenza-like illness refers to respiratory infections that produce symptoms resembling the flu, including fever and cough.

However, not every ILI case is caused by the influenza virus. Other respiratory pathogens can produce similar symptoms, making monitoring important in identifying changes in illness trends.

Respiratory infections can spread through droplets released when infected individuals cough or sneeze. Contact with contaminated surfaces may also contribute to transmission.

Health authorities continue to encourage regular handwashing, proper cough etiquette, and wearing a face mask when experiencing respiratory symptoms.

People who are sick are also advised to limit close contact with others, particularly individuals who may be more vulnerable to complications.

Mercado said the DOH is continuing to monitor respiratory illnesses, including COVID-19.

The department recorded 291 COVID-19 cases during the latest monitoring week, up from 245 in the preceding period.

However, the health chief said the figures had not reached epidemic proportions.

As the vaccination campaign approaches, the DOH continues to emphasize preventive measures to reduce the spread of respiratory infections, particularly ahead of the holiday season.
