As respiratory infections surge across China this winter, a lesser-known virus—human metapneumovirus (HMPV)—has drawn attention. However, health officials reassure that the rise is typical for the season.
What is HMPV?
HMPV is a respiratory virus causing upper and lower respiratory illnesses across all age groups. It was first identified in 2001, and almost all children are infected by age 5. Reinfections can occur throughout life.
China’s Current Respiratory Trends
Data from China’s CDC shows rising HMPV cases alongside other common viruses like seasonal flu and RSV. Despite this, Margaret Harris, a spokesperson for the World Health Organization, confirmed that infection levels are within normal seasonal ranges. Hospital utilization in China is lower than last year, and no emergency responses have been initiated.
HMPV in the United States
The U.S. CDC tracks HMPV similarly to other respiratory viruses. It accounts for 10-12% of respiratory illnesses in children. Recent data shows a low positivity rate of 1.94% for HMPV compared to 18.71% for flu and 7.10% for COVID-19.
Symptoms and Transmission
HMPV symptoms often resemble the common cold, including cough, fever, nasal congestion, and shortness of breath. The virus spreads via respiratory droplets or contaminated surfaces.
Preventive Measures
Health experts recommend staying home when sick, improving ventilation, wearing masks in crowded spaces, and covering coughs and sneezes.
Who’s at Risk?
The very young, the elderly, and those with weakened immune systems are more vulnerable to severe infections.
Treatment Options
There is no vaccine or specific antiviral for HMPV. Most cases resolve with rest, hydration, and over-the-counter medications within a week.
As respiratory virus season continues, officials emphasize vigilance while reassuring that current trends align with expected winter patterns.
