Introduction

Human metapneumovirus (hMPV) is a common pathogen that can cause both upper and lower respiratory tract infections, particularly in children, elderly adults, and immunocompromised hosts. In 2001, researchers in the Netherlands first identified HMPV from stored nasopharyngeal samples from 28 children with respiratory illness by using electron microscopy and random reverse transcription-polymerase chain reaction (RT-PCR) techniques. Despite its prevalence people have never heard of HMPV, that leaves them unprepared when the symptoms arise.

HMPV is thought to spread through direct or close contact with infected individuals or objects (fomites). The symptoms of HMPV looks similar to the other respiratory viruses, so it is neglected easily. HMPV has a seasonal variation: it circulates in late winter to early spring in temperate climates; late spring and summer in tropical regions. There is no specific antiviral treatment for HMPV or any vaccine for it so understanding its causes symptoms and how to manage it helps you protect your family and loved ones.

HMPV has gained attention in the whole world due to its role in respiratory outbreaks globally.  For instance, China has experienced a surge in HMPV cases, during the winter and spring months, that adds more pressure on healthcare systems already fighting seasonal flu and COVID-19. 

What is Human Metapneumovirus (HMPV)?

Human Metapneumovirus (HMPV) is a respiratory virus belongs to the Pneumoviridae family and is known to cause infections in the upper and lower respiratory tracts. The metapneumoviruses are enveloped, non-segmented, negative-sense, single-stranded RNA viruses. HMPV is responsible for a large portion of respiratory infections worldwide. Compared to influenza and RSV, HMPV tends to peak in later months and exhibits a seasonal distribution akin to that of other respiratory viruses. including other respiratory viruses, HMPV primarily affects young children and newborns, the elderly, and people with underlying chronic illnesses including emphysema, asthma, or compromised immune systems.

 Symptoms of HMPV

The symptoms of HMPV are almost similar to those of other respiratory viruses like the flu or Respiratory Syncytial Virus (RSV). The severity of these symptoms depends on the age and health of the patient. The common symptoms include are

• Cough
• Fever
• Nasal Congestion
• Sore Throat
• Shortness of Breath
• Wheezing
• Fatigue
• Headache

In high-risk groups (e.g., infants, elderly, or immunocompromised individuals), HMPV can lead to more serious complications, including:

• Bronchitis
• Pneumonia
• Worsening of asthma or chronic lung disease.
• Respiratory Distress

Duration of Symptoms:

Most symptoms take 7–14 days to resolve in healthy individuals. Cough and fatigue may persist for several weeks, especially in severe cases.

Causes and Transmission of HMPV

HMPV is a respiratory virus that can easily spread from one person to another. Understanding the mode of transmission can help to stop its spread. Here is the detailed look into it:

What Causes HMPV?

HMPV is caused by the Human Metapneumovirus, a member of the Pneumoviridae family and is related to the RSV. This virus primarily affects the respiratory tract, causing upper and lower airways infections.

How is HMPV Transmitted?

Here are the main modes of transmission of the HMPV

• By the Respiratory Droplets of an infected person when they cough, sneezes, or talks. These droplets are inhaled by person standing nearby, leading to the infection.
• Direct Contact with an infected person.
• Indirect Contact: Touching surfaces or objects contaminated with the virus.
• Close Proximity: Being in close contact with an infected person

Incubation period of HMPV

The time between exposure to the virus and the onset of symptoms is typically 3–6 days. During the incubation period, there are no symptoms, but virus is spreading in the body.

 Diagnosis of HMPV

Diagnosis of HMPV is challenging due to its simmilarity with those of other respiratory viruses such as Respiratory Syncytial Virus (RSV), influenza, and COVID-19. The diagnosis requires labortary testing to confirm HMPV

a. Polymerase Chain Reaction (PCR) Test: It is highly sensitive and considered as a Gold standard in diagnosis of HMPV due to its accuracy.

b. Antigen Testing: It detects viral proteins (antigens) in respiratory samples taken from nasal or throat swab. It is faster than PCR but less sensitive.

c. Viral Culture:  It is rarely used for routine diagnosis due to the time required (several days to weeks).

Treatment for HMPV

Treatment consists of supportive care as there are no licensed antivirals against HMPV. Two potential treatments that have been investigated 

•  Ribavirin
•  Immunoglobulin

Management of HMPV mainly focuses on supportive care to relieve symptoms and prevent complications, especially in high-risk individuals. 

Supportive Care for HMPV

• Rest
• Hydration
• Fever and Pain Management
• Cough Management
• Oxygen Therapy

High risk individuals may require hospitalization for the management of complications related to HMPV.

Prevention of HMPV

Since there is no specific vaccine or antiviral treatment for Human Metapneumovirus (HMPV), so the most effective way to reduce the risk of infection is prevention of infection.  Practical prevention tips are following:

• Hand hygiene (frequent handwashing)
• Avoiding close contact with infected individuals
• Wearing masks in crowded places
• Disinfecting frequently touched surfaces.
•  Vaccination for Other Respiratory Viruses to prevent coinfection
• Special Precautions for High-Risk Groups

Conclusion

• HMPV is a significant cause of respiratory illness, particularly in high-risk groups.
• Prevention through good hygiene and avoiding close contact with sick individuals is crucial.
• Supportive care is the mainstay of treatment, as there is no specific antiviral or vaccine for HMPV.
• Stay informed and take proactive steps to protect yourself and others during respiratory virus season.

FAQ’s

Who is most at risk for HMPV?

HMPV causes most severe disease in infants and young children, the elderly, and persons with underlying chronic conditions such as asthma, emphysema, and immune compromise.

Is HMPV contagious?

Yes, it is contagious. An infected person can spread the virus during the incubation period and while symptoms are present.

Is there a vaccine for HMPV?

There are currently no licensed vaccines for HMPV, but numerous efforts have been made to develop a safe and effective vaccine.

Can HMPV cause severe illness?

Yes, HMPV can cause severe respiratory illness, particularly in high-risk groups.
