Human Metapneumovirus (hMPV)

What is Human Metapneumovirus (hMPV)?

Human Metapneumovirus (hMPV) is a respiratory virus that can cause illnesses ranging from mild cold-like symptoms to severe lower respiratory tract infections like bronchiolitis and pneumonia. Discovered in 2001, it has recently gained attention due to a surge in cases reported in China. While hMPV often results in mild infections, it remains a concern, particularly for vulnerable groups.

Who is Most at Risk?

hMPV can affect anyone, but certain groups are more susceptible to severe complications:

• Infants
• Young children
• Children with chronic respiratory conditions (e.g., asthma)
• Immunocompromised children

Symptoms of hMPV in Children

The symptoms of hMPV can vary depending on the severity of the infection.

Mild Symptoms:

• Runny nose
• Cough
• Nasal congestion
• Sore throat
• Low-grade fever

Severe Symptoms (Require Immediate Attention):

• Wheezing
• Rapid or labored breathing
• Persistent high fever
• Fatigue or lethargy
• Difficulty feeding or loss of appetite
• Signs of dehydration (e.g., reduced urination, dry mouth)

In severe cases, hMPV can lead to hospitalization due to complications like bronchiolitis or pneumonia.

How Does hMPV Spread?

hMPV is highly contagious and spreads through:

• Respiratory droplets from coughs or sneezes of an infected person
• Touching contaminated surfaces like toys or doorknobs and then touching the mouth, nose, or eyes
• Close contact with an infected individual

The virus is most active during late winter and spring, similar to other respiratory viruses.

Prevention Strategies for hMPV

Although there is no vaccine for hMPV, several preventive measures can help reduce the risk of infection:

1. Practice Proper Hand Hygiene:

• Teach children to wash their hands thoroughly with soap and water.
• Use alcohol-based hand sanitizers when soap isn’t available.

2. Avoid Close Contact with Sick Individuals:

• Keep children away from those showing symptoms of illness.
• Avoid crowded places during peak respiratory virus seasons.

3. Disinfect Commonly Touched Surfaces:

• Regularly clean toys, doorknobs, and other frequently touched surfaces.

4. Boost Immunity:

• Provide a balanced diet rich in vitamins and minerals.
• Ensure your child gets adequate sleep and stays hydrated.

5. Keep Sick Children Home:

• If your child shows signs of illness, avoid sending them to school to limit the spread.

When to Seek Medical Attention

Most cases of hMPV are mild and can be managed at home with rest, hydration, and symptom relief. However, seek immediate medical attention if your child:

• Has difficulty breathing or wheezing
• Develops a high fever unresponsive to medication
• Shows signs of dehydration (e.g., dry mouth, reduced urination)
• Becomes excessively drowsy, irritable, or unresponsive
• Experiences worsening symptoms despite home care

Children with underlying conditions such as asthma or compromised immune systems require closer monitoring.

Frequently Asked Questions About hMPV

1. Can adults get hMPV?

Yes, adults can also contract hMPV, but symptoms are typically milder and resemble the common cold. However, older adults and immunocompromised individuals may experience more severe symptoms.

2. Is hMPV the same as RSV?

No, hMPV and RSV are different viruses, though they cause similar respiratory illnesses. RSV is more widely recognized, but hMPV is equally significant in respiratory infections, especially in children.

3. How long does an hMPV infection last?

Symptoms usually last 1 to 2 weeks, though severe cases may take longer to resolve.

4. Is there a specific treatment for hMPV?

There is no specific antiviral treatment for hMPV. Management focuses on symptom relief, such as fever-reducing medications, hydration, and rest.

5. Can children get reinfected with hMPV?

Yes, reinfection is possible as immunity from prior infections is not long-lasting. However, subsequent infections are usually milder.

6. Which children are at higher risk for severe hMPV?

• Infants, particularly under six months
• Premature babies
• Children with chronic respiratory or cardiac conditions
• Immunocompromised children
