Everything you need to know about human metapneumovirus (HMPV)
Human metapneumovirus (HMPV) is a common respiratory virus that often goes unnoticed, yet it can significantly affect many people.

We will also share valuable insights on accessing quality healthcare at Apex Multispeciality Hospital, a top facility in Kalewadi, PCMC, Pune, ensuring you have the best support when needed.
What Is Human Metapneumovirus (HMPV)?
HMPV belongs to the same family as respiratory syncytial virus (RSV) and causes cold-like symptoms such as cough, fever, and nasal congestion. Discovered in 2001, it has circulated globally for decades, with most children exposed by age five. While mild for many, it can lead to severe bronchitis or pneumonia in infants, older adults, and immunocompromised individuals.
How is HMPV Transmitted?
HMPV spreads through close contact with infected individuals. The virus can be transmitted via:
- Respiratory droplets are released during coughing or sneezing.
- Touching contaminated surfaces (e.g., doorknobs, toys) and touching the mouth, nose, or eyes.
In temperate regions, HMPV typically circulates during late winter and spring, coinciding with other respiratory viruses like RSV and influenza.
Symptoms by Age Group:
- Adults Cough, fever, nasal congestion, sore throat, fatigue
- Children Wheezing, rapid breathing (up to 50 breaths/minute), bronchiolitis, pneumonia
- High-risk groups Severe shortness of breath, pneumonia, hospitalization needs
Key facts:
- Spreads through coughs, sneezes, or contaminated surfaces.
- Peaks in late winter and spring in temperate areas.
- No specific vaccine or antiviral treatment exists.
Symptoms and Risks of HMPV Infection:
Most cases mimic the common cold, but severe symptoms include:
- Trouble breathing or wheezing
- Persistent high fever (>100.4°F)
- Fatigue and muscle pain
- Worsening cough or chest tightness
If you or your child experiences a high fever or difficulty breathing, it is essential to seek medical attention promptly.
HMPV vs. Other Respiratory Viruses:
While HMPV shares symptoms with other respiratory viruses, certain distinctions exist:
- Influenza: Often causes more systemic symptoms like body aches and fatigue.
- RSV: Primarily affects young children and can lead to severe lower respiratory tract infections.
Understanding these distinctions helps in accurate diagnosis and treatment.
Diagnosis of HMPV:
Diagnosing HMPV involves:
- PCR Testing: Detects viral RNA in respiratory specimens.
- Antigen Detection: Identifies viral proteins.
However, due to overlapping symptoms with other viruses, misdiagnosis can occur. Healthcare providers may need to conduct multiple tests to confirm HMPV.
Treatment Options for HMPV:
Currently, No specific antiviral drugs or vaccines exist
Management focuses on supportive care:
- Rest: Allows the body to combat the infection.
- Hydration: Helps thin mucus and prevent dehydration.
- Over-the-Counter Medications: To alleviate pain and reduce fever.
In severe cases, particularly among high-risk groups, hospitalization may be necessary for oxygen therapy or mechanical ventilation.
Prevention Strategies:
Preventing HMPV involves:
- Hand hygiene: Wash hands frequently with soap for 20 seconds.
- Surface disinfection: Clean doorknobs, phones, and toys regularly.
- Masking: Wear masks in crowded or poorly ventilated areas.
- Boost immunity: Prioritize sleep, nutrition, and exercise.
Currently, no vaccine is available for HMPV, highlighting the importance of these preventive measures.
Myths vs. Facts:
Myth: HMPV is a new pandemic threat.
Fact: It’s a known seasonal virus with no pandemic potential
Myth: COVID-19 vaccines offer no protection.
Fact: While no HMPV vaccine exists, flu and COVID-19 shots reduce overall respiratory risks
Recent Trends:
- China: A 2025 winter surge in HMPV cases prompted school closures but was deemed non-pandemic by WHO.
- India: Seven cases were reported in Gujarat, Tamil Nadu, and Karnataka in January 2025. Health authorities confirm no public health emergency.
The World Health Organization (WHO) notes these spikes align with typical seasonal patterns and urges vigilance without panic.
Complications of Human Metapneumovirus (HMPV):
HMPV infections range from mild to severe, especially in high-risk groups.
- Respiratory Issues– Bronchiolitis, pneumonia, ARDS, and worsened COPD/asthma symptoms.
- Systemic Effects– Kidney injury, neurological issues (seizures, encephalitis), and liver abnormalities.
- High-Risk Groups– Elderly, immunocompromised, obese individuals, diabetics, and pregnant women face severe complications.
- Secondary Infections– Higher risk of bacterial infections, sepsis, and ECMO support in critical cases
