Low influenza, HMPV cases in PH despite rising numbers in China, says DOH

MANILA, Philippines — The Department of Health (DOH) reported a decline in influenza-like illness (ILI) cases in 2024, reassuring the public that the numbers remain low despite rising concerns about respiratory infections in other countries, particularly China.  

The Philippines recorded 179,227 ILI cases by the end of 2024, reflecting a 17% drop from the 216,786 cases logged in 2023, according to the ILI Surveillance System. Symptoms of ILI include fever, cough and colds, which can be caused by various respiratory viruses.  

“This decrease may be attributed to better health-seeking behaviors and practices and better preparations by the health sector,” the DOH said in a statement.  

According to the DOH, the top five culprits for ILIs in the country are rhinovirus, enterovirus, Influenza A, respiratory syncytial virus (RSV) and adenovirus. 

Meanwhile, the Human metapneumovirus (HMPV), the sixth most common virus causing ILIs in 2024, accounted for only a small fraction of cases. 

Of the 4,921 positive samples across six identified viruses, only 284 tested positive for HMPV as of Dec. 21, 2024. From December 1 to December 21, just 10 cases — or 2.9% of the total — were reported.  

The DOH emphasized that HMPV detections were sporadic and showed no unusual clustering or demographic patterns in the country.  

No trend of HMPV infections. Health Secretary Teodoro Herbosa also clarified the HMPV is not new and was discovered in 2001 in relation to respiratory infections. 

“HMPV is not a new virus. We have been able to identify it for a long time. Its symptoms are not severe. Like the common cough and cold, it heals on its own as long as our resistance is strong,” he said. 

Common symptoms of HMPV include cough, fever, nasal congestion and wheezing. In rare cases, individuals with weakened immune systems or preexisting conditions may develop bronchitis or pneumonia.  

To prevent respiratory illnesses, the DOH urged the public, particularly children, the elderly and immunocompromised individuals, to practice good hygiene.  

“The DOH reminds the general public, especially the young, immunocompromised, and elderly, to take caution by frequently washing their hands,
