Human Metapneumovirus (HMPV): Symptoms, Treatment, Prevention & Global Impact
Introduction
Human Metapneumovirus (HMPV) is a respiratory virus from the Pneumoviridae family, first identified in 2001. It shares similarities with Respiratory Syncytial Virus (RSV) and primarily affects young children, the elderly, and immunocompromised individuals. Recently, two cases of HMPV were reported in Bengaluru, India, drawing public health attention.
This article explores HMPV symptoms, transmission, treatment options, prevention strategies, and its global impact.

What is HMPV?
HMPV is a seasonal virus that circulates mainly in winter and spring, causing respiratory infections that mimic symptoms of the common cold or flu. Despite being identified over two decades ago, public awareness remains limited compared to influenza and COVID-19.
Symptoms of HMPV
Mild Symptoms
- Runny or congested nose
- Cough
- Sore throat
- Fever
- Shortness of breath (mild cases)
Severe Symptoms (Common in high-risk individuals)
- Bronchitis: Persistent coughing and mucus production
- Pneumonia: Lung infection causing chest pain and breathing difficulties
- Asthma exacerbation: Worsening of existing asthma conditions
- Ear infections: Particularly common in children
How Does HMPV Spread?
HMPV is highly contagious, spreading through:
- Respiratory droplets from coughing, sneezing, or talking
- Close contact with infected individuals
- Touching contaminated surfaces and then touching the face
The infection typically lasts 3–5 days, but reinfection is possible, as previous infections do not grant long-term immunity.
Diagnosis & Treatment
Diagnosis
Doctors diagnose HMPV through nasal/throat swabs and, in severe cases, additional tests such as:
- Chest X-rays: To detect pneumonia
- Bronchoscopy: For examining airway complications
Treatment
There is no specific antiviral therapy or vaccine for HMPV. Treatment focuses on symptom management:
- Oxygen therapy for breathing difficulties
- Intravenous (IV) fluids to prevent dehydration
- Corticosteroids to reduce inflammation and improve respiratory function
Prevention: How to Protect Yourself
While no vaccine exists, the following precautions can reduce HMPV transmission:
- Frequent handwashing with soap and water
- Avoid touching the face (mouth, nose, eyes)
- Wear masks in crowded spaces
- Stay home when sick to prevent spreading the virus
- Disinfect high-touch surfaces regularly
HMPV vs. COVID-19: Key Differences
| Feature | HMPV | COVID-19 |
|---|---|---|
| Symptoms | Fever, cough, congestion, wheezing | Fever, cough, loss of taste/smell, fatigue |
| Transmission | Respiratory droplets, close contact | Respiratory droplets, airborne transmission |
| Vaccine Available? | ❌ No | ✅ Yes |
| Severity | Seasonal, mainly affects vulnerable groups | Can cause global outbreaks |
Global Outbreaks & Recent Developments
China & Neighboring Countries
- China: Hospitals reported a surge in HMPV cases but reassured the public it follows seasonal trends.
- Malaysia: Cases increased by 45% from 2023 to 2024.
- Japan: Recorded 94,000+ influenza cases, making respiratory infections a growing concern.
FAQs: Common Questions About HMPV
1. Is HMPV life-threatening?
For most people, HMPV is mild. However, it can cause severe respiratory issues in children, elderly individuals, and those with weakened immune systems.
2. Can you get HMPV more than once?
Yes. Immunity after infection is not long-lasting, meaning reinfection is possible.
3. How is HMPV different from RSV?
Both belong to the Pneumoviridae family, but RSV tends to cause more severe infections in infants.
4. What are the best ways to prevent HMPV?
Handwashing, avoiding sick individuals, disinfecting surfaces, and wearing masks can help reduce transmission.
5. Is there a vaccine for HMPV?
Currently, no vaccine exists, but research is ongoing.
Conclusion & Call to Action
HMPV, though less well-known than COVID-19 or influenza, is a significant global health concern due to its impact on vulnerable populations. Since there is no vaccine or direct treatment, taking preventive measures is crucial.
