7-1-2025 (HANOI) The human metapneumovirus (HMPV) currently spreading in China is a well-documented pathogen rather than a novel virus, Ho Chi Minh City’s Department of Health announced today. The virus, which commonly causes respiratory infections in children, has been previously identified and monitored in the Vietnamese metropolis.
According to surveillance data, Ho Chi Minh City recorded between 16,000 and 18,000 respiratory infection cases monthly during the first eight months of 2024, with a seasonal uptick observed in the final quarter. Despite the traditional increase in respiratory ailments during colder weather, health authorities report no unusual spikes in case numbers or severity.
A comprehensive study conducted by a consortium of research institutions, including the Oxford University Clinical Research Unit (OUCRU), Hospital for Tropical Diseases, and Singapore National Centre for Infectious Diseases, has revealed that conventional pathogens remain the primary causes of respiratory infections.
Analysis of 103 community-acquired pneumonia cases at the Ho Chi Minh City Hospital for Tropical Diseases between July and December revealed HMPV presence in just 12.5% of paediatric cases. More prevalent pathogens in children included H. influenzae (71.4%), S. pneumoniae (42.9%), and rhinovirus (44.6%). Among adult patients, influenza A virus dominated at 48.9%, followed by H. influenzae (42.6%).
Whilst maintaining a measured approach, health officials emphasise the importance of continued vigilance. The Department has instructed the City Centre for Disease Control to maintain robust surveillance of global developments and strengthen medical quarantine protocols at entry points.
The virus, first identified in 2001, belongs to the Pneumoviridae family and shares characteristics with respiratory syncytial virus (RSV). Transmission occurs through direct contact or contaminated surfaces, with peak infection rates typically occurring during winter and early spring.
Despite the current situation remaining stable, authorities have implemented comprehensive monitoring measures, including tracking respiratory infections, hospitalisation rates, and potential outbreak clusters in schools and communities. With no specific treatment or vaccine available, officials stress the importance of preventive measures in managing potential transmission risks.
“Whilst HMPV is not a new threat, we maintain our commitment to rigorous surveillance and preparedness,” a departmental spokesperson stated, underlining the importance of sustained public health measures despite the familiar nature of the pathogen.
