Human Metapneumovirus (HMPV)

Human Metapneumovirus (HMPV) is a type of virus that affects the respiratory system, causing infections in people of all ages. It was first identified in 2001 and has since been recognized as a significant cause of respiratory illness worldwide.

What is HMPV?

HMPV is a single-stranded RNA virus that belongs to the Pneumoviridae family. It is closely related to the Respiratory Syncytial Virus (RSV) and shares similar characteristics. HMPV is highly contagious and can spread through respiratory droplets, contact with contaminated surfaces, and close contact with an infected person.

Symptoms of HMPV

The symptoms of HMPV infection can range from mild to severe and may include:

• Coughing
• Runny nose
• Sneezing
• Sore throat
• Fever
• Headache
• Muscle aches
• Fatigue
• Shortness of breath
• Wheezing

In severe cases, HMPV can cause:

• Bronchiolitis (inflammation of the small airways)
• Pneumonia (infection of the lungs)
• Acute respiratory distress syndrome (ARDS)

Risk Factors

Certain groups of people are at higher risk of developing severe HMPV infection, including:

• Young children under the age of 2
• Older adults over the age of 65
• People with underlying medical conditions, such as heart disease or lung disease
• Those with weakened immune systems, such as people with HIV/AIDS or undergoing chemotherapy

Treatments for HMPV

There is no specific treatment for HMPV infection, and most cases are managed with supportive care to relieve symptoms. This may include:

• Rest and hydration
• Over-the-counter medications, such as acetaminophen or ibuprofen, to reduce fever and relieve pain
• Cough suppressants or expectorants to help manage coughing
• Oxygen therapy to help increase oxygen levels in the blood
• Antibiotics may be prescribed if a secondary bacterial infection develops

In severe cases, hospitalization may be necessary to provide:

• Close monitoring of vital signs and oxygen levels
• Supportive care, such as mechanical ventilation or supplemental oxygen
• Antiviral medications, such as ribavirin, which may be effective in treating HMPV infection

Prevention

To reduce the risk of HMPV transmission:

• Practice good hygiene, such as frequent handwashing and proper disposal of tissues
• Avoid close contact with people who are sick
• Stay home from work or school if you are experiencing symptoms
• Get vaccinated against influenza and other respiratory viruses to reduce the risk of co-infection
