Five years after the COVID pandemic, China is experiencing a surge in HMPV cases, particularly in children under 14 years of age

Key Highlights:

• What is HMPV?
  • A respiratory virus from the Pneumoviridae family, discovered in 2001.
  • Causes both upper and lower respiratory tract infections, similar to the common cold or flu.
• Origin and Discovery:
  • Identified in the Netherlands in 2001 through genomic sequencing of respiratory samples.
• Risk Groups:
  • Children under 5 years, especially infants.
  • Elderly individuals (65+).
  • Immunocompromised persons and those with chronic respiratory conditions (e.g., asthma).
• Symptoms:
  • Common: Cough, runny nose, fever, sore throat.
  • Severe: Wheezing, shortness of breath, potentially leading to bronchitis or pneumonia.
• Incubation Period: 3-6 days.
• Transmission:
  • Spread via droplets from coughing or sneezing.
  • Close contact (e.g., handshakes, hugs).
  • Contaminated surfaces, touching face after contact.
• Treatment:
  • No specific antiviral treatment or vaccine available.
  • Symptom management: hydration, rest, OTC medications for fever and congestion.
  • Severe cases may require hospitalization (oxygen therapy, IV fluids).
• Diagnosis:
  • NAATs (Nucleic Acid Amplification Tests): Detect viral genetic material.
  • Antigen-based immunoassays: For severe cases or outbreaks.
• Complications:
  • Can lead to bronchiolitis, bronchitis, pneumonia, asthma, or COPD flare-ups.
  • Risk of ear infections (otitis media) in some cases.
• Prevention:
  • Hygiene: Regular handwashing, covering coughs/sneezes, maintaining personal hygiene.
  • Physical Distancing: Avoid close contact, wear masks in crowded settings.
  • Caution for Vulnerable Groups: Extra care for individuals with chronic respiratory conditions.

Global Situation:

• China: Experiencing a rise in HMPV cases, particularly among children under 14 years.
• India: No reported cases yet, but monitoring the situation closely.

Key Facts:

• HMPV is a winter virus commonly seen in colder months (winter and early spring).
• Estimated 10%-12% of respiratory illnesses in children are caused by HMPV.
• The virus is part of the Pneumoviridae family, alongside respiratory syncytial virus (RSV), measles, and mumps.

No specific antiviral treatment or vaccine for HMPV; antibiotics are ineffective.
