A significant decline in cases of influenza-like illnesses (ILI) and dengue was recorded in the first 18 days of 2025 compared to the same period last year, the Department of Health (DOH) bared.

 

Per the latest DOH data as of Jan. 18, a total of 5,789 ILI cases were recorded nationwide, marking a 54 percent decrease from the 12,620 cases reported in early 2024. 

 

The number of deaths due to ILI also saw a drastic drop, with only one fatality recorded so far this year compared to 26 deaths during the same period last year—a 96 percent decline.

 

The health department identified the top six causative agents of ILI for January 1 to 18, 2025, as Influenza A, Influenza B, Rhinovirus, Enterovirus, Respiratory Syncytial Virus (RSV), and Adenovirus.

 

Meanwhile, dengue cases also showed an 8 percent decline, with 10,842 cases reported nationwide so far this year, compared to 11,781 cases in the same period in 2024. 

 

The DOH noted that the number of dengue-related deaths was cut in half, with 21 fatalities recorded this year compared to 42 last year.

 

Despite the downward trend, the DOH cautioned that late consultations and delayed reports could still affect the final case tally. 

 

The agency said it continues to monitor disease trends closely and urges the public to take preventive measures, especially as fluctuating weather conditions could still contribute to the spread of viral infections.
