Human Metapneumovirus (HMPV): Symptoms, Diagnosis, and Treatment Information – Dr. Aamir Shaikh, Fertility Super Specialist, KGN Test Tube Baby Hospital, Latur

Human Metapneumovirus (HMPV) is a respiratory virus that primarily affects the lungs and airways. It was first identified in 2001 and belongs to the Paramyxoviridae family, which also includes the respiratory syncytial virus (RSV) that causes the common cold. Though not as well-known as other respiratory viruses, HMPV can still cause significant infections, especially in young children, the elderly, and those with weakened immune systems. The virus spreads easily through respiratory droplets when an infected person coughs, sneezes, or talks.


Symptoms and Causes


The symptoms of HMPV infection are similar to those caused by other respiratory viruses and can range from mild to severe. They include:


  • Cough

  • Nasal congestion or runny nose

  • Fever

  • Shortness of breath

  • Sore throat

  • Fatigue

  • Headache


In some cases, individuals may experience more severe symptoms, such as pneumonia or bronchiolitis, which may require hospitalization, especially for young children, the elderly, or those with pre-existing conditions such as asthma or heart disease.

HMPV infection spreads through respiratory droplets or by touching contaminated surfaces. The virus is most common at the end of winter and the beginning of spring.


Diagnosis and Tests

The diagnosis of HMPV usually begins with a thorough medical history and physical examination. If other common respiratory viruses, such as the flu or RSV, are ruled out, HMPV may be suspected.


The following tests may be conducted for diagnosis:

  • Polymerase Chain Reaction (PCR) Test: This is the most common and accurate test to detect HMPV. A sample from the nose or throat is taken to examine the viral genetic material.

  • Rapid Antigen Test: This test detects the virus's proteins and provides faster results but may be less sensitive than PCR.

  • Chest X-ray or CT Scan: These tests may be performed to evaluate lung involvement in cases of severe symptoms, such as pneumonia.

  • Blood Tests: These tests are used to check for signs of infection or complications.


Management and Treatment

There is no specific antiviral treatment for HMPV. Treatment mainly focuses on relieving symptoms and providing supportive care. Common treatment methods include:


  • Hydration: It is crucial to stay hydrated, especially for young children and the elderly, to prevent dehydration.

  • Rest: Adequate rest helps the body recover.

  • Medications:

    • Pain relievers (e.g., Paracetamol or Ibuprofen) can be used to reduce fever and body aches.

    • Cough suppressants may help manage persistent coughing.

    • Nasal decongestants are used to alleviate nasal congestion.


In severe cases, especially those at high risk, hospitalization may be necessary. Oxygen therapy or mechanical ventilation may be used if respiratory support is required

.

Prevention

Preventing HMPV infection involves good hygiene practices and reducing the spread of the virus. Effective preventive measures include:


  • Frequent Handwashing: Wash hands thoroughly with soap and water after contact with cold, cough, or contaminated surfaces.

  • Avoid Close Contact: Avoid close contact with infected individuals, especially during peak respiratory virus seasons.

  • Cover Mouth and Nose: Use a tissue or elbow to cover your mouth and nose when coughing or sneezing to reduce the spread of droplets.

  • Clean Surfaces: Disinfect frequently touched surfaces like door handles, phones, and toys.

  • Stay Home When Sick: If you or your child are experiencing symptoms of respiratory illness, stay home to prevent spreading the infection to others.


Outlook / Prognosis

Most people with HMPV infection recover completely without specific treatment. However, the virus can lead to serious complications, particularly in the elderly, young children, or those with compromised immune systems. In these cases, the infection may lead to severe respiratory conditions such as pneumonia or bronchiolitis, which may require hospitalization.


With appropriate care, most patients recover within one to two weeks. However, individuals with underlying health conditions may require more intensive treatment and care.


Conclusion

Human Metapneumovirus (HMPV) is a respiratory virus that can cause mild to severe symptoms, especially in individuals with weakened immune systems. While there is no specific antiviral treatment, supportive care and preventive measures can help reduce the risk of infection. If you or your loved ones are experiencing respiratory symptoms, it is important to seek medical advice and receive appropriate treatment.
