What You Need to Know About HMPV: The Respiratory Virus You’ve Never Heard Of

With winter here and reports of a major outbreak in China, now is a good time to get familiar with a lesser-known but significant viral threat called Human Metapneumovirus (HMPV). First discovered in 2001, this respiratory virus has emerged as a leading cause of acute respiratory infections, particularly affecting young children, older adults, and those with compromised immune systems.

Understanding HMPV

HMPV belongs to the same family as RSV (Respiratory Syncytial Virus) and can cause both upper and lower respiratory infections. While many people experience mild cold-like symptoms, the virus can progress to more serious conditions like bronchitis or pneumonia in vulnerable populations.

Key Symptoms to Watch For

  • Cough
  • Fever
  • Nasal congestion
  • Shortness of breath
  • Sore throat

Who’s at Risk?

While anyone can contract HMPV, certain groups face higher risks of complications:

  • Children under 5 years old
  • Adults over 65
  • People with weakened immune systems
  • Individuals with underlying lung conditions (such as asthma or COPD)

Transmission and Prevention

HMPV spreads similarly to other respiratory viruses through:

  • Respiratory droplets from coughing and sneezing
  • Close personal contact (touching, handshaking)
  • Touching contaminated surfaces then touching your face

Prevention Tips

  • Wash hands frequently with soap and water for at least 20 seconds
  • Avoid touching your face with unwashed hands
  • Keep distance from sick individuals
  • Clean frequently touched surfaces regularly
  • Stay home when sick

Treatment Options

Currently, there’s no specific antiviral treatment or vaccine for HMPV. Treatment focuses on managing symptoms:

  • Over-the-counter pain relievers and fever reducers
  • Decongestants for nasal symptoms
  • Inhalers or corticosteroids may be prescribed for severe cases
  • Rest and adequate hydration

When to Seek Medical Care

While most cases resolve on their own, seek medical attention if you experience:

  • Severe difficulty breathing
  • Persistent high fever
  • Worsening symptoms after initial improvement
  • Symptoms that don’t improve after a week

Important Note

HMPV is most active during late winter and spring, often circulating alongside RSV and influenza. If you’re experiencing respiratory symptoms during these seasons, consider asking your healthcare provider about HMPV testing, particularly if you’re in a high-risk group.
