Medical News: In a recent warning issued on April 18, Dr Li Shang-chien, a distinguished pediatric infectious diseases specialist at Landseed International Hospital, highlighted a looming threat in Taiwan - a potential outbreak of the human metapneumovirus (hMPV). This cautionary note was prompted by the emergence of cases characterized by persistent high fevers.
Taiwan Is Facing A Human Metapneumovirus (hMPV) Outbreak As Fever Cases Rise
Understanding hMPV: An Overview
Human metapneumovirus, often abbreviated as hMPV, is a globally prevalent virus known for its impact on the upper respiratory system. It shares similarities with COVID-19 in terms of symptoms such as cough, sore throat, and fever. However, hMPV poses a heightened risk to specific demographics, including children, older adults, and individuals with compromised immune systems.
The Seasonal Pattern and Transmission
Typically, prevalent during winter and early spring, hMPV follows a seasonal trajectory akin to respiratory syncytial virus (RSV) and influenza. The virus spreads through droplets, direct contact, and indirect exposure, raising concerns about potential co-infections with other respiratory pathogens.
Clinical Manifestations Across Age Groups
Dr Li emphasized that hMPV doesn't discriminate based on age, affecting both children and the elderly. In children, symptoms commonly include coughing, runny nose, wheezing, hoarseness, and persistent fever. Hospitalization is often necessitated by complications like acute bronchiolitis and pneumonia. On the other hand, adults may experience coughing, nasal congestion, runny nose, and hoarseness, with fever being less prevalent. Elderly patients may exhibit breathing difficulties and wheezing, while hoarseness is more common among younger individuals.
HMPV: The Silent Threat Amidst COVID-19 and Influenza
While RSV, influenza, and COVID-19 have been dominant in recent winters, hMPV has quietly emerged as a significant concern. Surveillance data from the US Centers for Disease Control and Prevention (CDC) indicate a notable increase in hMPV cases during the spring months. This surge has led to a higher representation of young children and the elderly in intensive care units due to hMPV-related complications.
What Sets hMPV Apart
Discovered in 2001, hMPV belongs to the Pneumoviridae family, sharing lineage with respiratory syncytial virus. Despite its relatively recent identification, hMPV's impact is comparable to other well-known respiratory viruses like RSV and influenza. Dr John Williams, a prominent researcher specializing in hMPV, has referred to it as "the most important virus you've never heard of," underscoring its clinical significance.
Recognizing Symptoms and Severity
Common symptoms of hMPV include cough, fever, nasal congestion, and shortness of breath. While these symptoms may resolve within a few days for healthy individuals, severe cases can lead to wheezing, breathing difficulties,
and exacerbation of underlying conditions like asthma. Secondary infections such as bronchiolitis and pneumonia are also potential complications requiring medical attention.
Urgent Measures for Prevention and Management
Dr Li's recommendations emphasize the importance of proactive measures such as frequent hand washing and adherence to personal hygiene practices. Early detection and prompt medical intervention are crucial, especially for individuals experiencing persistent fever, cough, or respiratory distress.

Incubation Period and Transmission Dynamics
The typical incubation period for hMPV ranges from five to six days, aligning with its seasonal prevalence in colder months. Transmission occurs primarily through respiratory droplets, highlighting the need for vigilance during periods of increased respiratory virus activity.
Conclusion: Mitigating the Threat of hMPV
As Taiwan faces the potential challenge of an hMPV outbreak, public awareness, preventive strategies, and clinical preparedness are paramount. Dr. Li's warning serves as a crucial reminder of the ongoing threat posed by respiratory viruses, urging proactive measures to safeguard community health and well-being.
Thailand
Medical News would like to add that there are strong suspicions that newer emerged strains of the hMPV virus could be at play as the outbreak seems to cause more disease severity this time round in both children and adults with rising hospitalizations being reported. Urgent research is needed to look into this.
