What is HMPV Virus? when did the virus come ?
The Human Metapneumovirus (hMPV) is a respiratory virus that primarily affects the upper and lower respiratory tracts. It is a common cause of respiratory infections, particularly in young children, the elderly, and individuals with weakened immune systems.
Discovery: hMPV was first identified in 2001.
Family: It belongs to the Paramyxoviridae family, similar to respiratory syncytial virus (RSV).
Symptoms: Symptoms can range from mild cold-like symptoms to severe respiratory illness. Common symptoms include:
Cough
Runny nose
Fever
Shortness of breath
Wheezing (in severe cases)
Transmission: The virus spreads through respiratory droplets (e.g., coughing, sneezing), close contact with an infected person, or touching contaminated surfaces.
Current Situation:
Prevalence: Recent data indicates that HMPV accounts for 6.2% of positive respiratory illness tests and 5.4% of respiratory-related hospitalizations in China, surpassing rates for COVID-19, rhinovirus, and adenovirus.
Symptoms: HMPV typically causes flu-like symptoms, including cough, fever, and nasal congestion. In severe cases, it can lead to bronchitis or pneumonia, especially in infants, the elderly, and immunocompromised individuals.
Healthcare Impact: Hospitals in affected regions are experiencing increased patient volumes, raising concerns about healthcare system capacity.
Expert Insights:
Seasonal Trends: Health experts note that respiratory infections, including HMPV, typically peak during winter. The current rise aligns with expected seasonal patterns.

Global Monitoring: The U.S. Centers for Disease Control and Prevention (CDC) is monitoring the situation, noting a concurrent increase in HMPV cases in the United States, though at pre-pandemic levels.
Preventive Measures:
Hygiene Practices: Regular handwashing, avoiding close contact with sick individuals, and disinfecting frequently touched surfaces are recommended to reduce transmission.
Symptom Management: Currently, there is no specific antiviral treatment or vaccine for HMPV. Management focuses on relieving symptoms, such as ensuring adequate hydration and rest.
How does HMPV spread?
HMPV is transmitted through respiratory droplets from coughing or sneezing, close contact like handshakes or touching, and contact with contaminated surfaces followed by touching the mouth, nose, or eyes. According to the CDC, the virus follows a seasonal pattern, typically circulating during late winter and spring in temperate areas.
What can you do to prevent it?
The CDC advises taking these measures to lower the risk of HMPV and other respiratory infections:
Wash hands often with soap and water for at least 20 seconds.
Avoid touching your face with unwashed hands.
Wear masks in crowded areas during outbreaks.
Stay home when unwell to prevent spreading the virus.
Clean frequently touched surfaces regularly.
