China is currently experiencing a significant increase in human metapneumovirus (HMPV) cases, raising concerns about a potential health crisis in the wake of the COVID-19 pandemic. Reports and social media posts reveal overcrowded hospitals and the circulation of multiple respiratory viruses, including HMPV, influenza A, Mycoplasma pneumoniae, and COVID-19. Here's what you need to know about HMPV and its impact.
What is HMPV and why is it making headlines in China?
Human metapneumovirus (HMPV) is a respiratory virus known to cause upper and lower respiratory tract infections. First identified in 2001, it affects people of all age groups. However, it is particularly serious for young children, older adults, and those with weakened immune systems, as noted by the US Centers for Disease Control and Prevention (CDC). The current outbreak in China has put this virus in the spotlight due to its rapid spread and the pressure it is putting on healthcare facilities.
Symptoms of HMPV
The symptoms of HMPV are similar to those caused by the flu and other respiratory viruses, which can complicate diagnosis. Common symptoms include:
Cough Fever Nasal congestion Shortness of breath
In severe cases, HMPV can cause bronchitis or pneumonia, which are life-threatening, especially in high-risk groups. The virus has an incubation period of 3 to 6 days and the duration of symptoms varies depending on the severity of the infection.

How HMPV spreads
HMPV spreads through mechanisms typical of respiratory viruses, such as:
Respiratory secretions: Coughing and sneezing release droplets that can infect others. Close personal contact: Touching or shaking hands with an infected person increases the risk of transmission. Contaminated surfaces: Touching objects contaminated with the virus and then touching your mouth, nose, or eyes. can cause infection.
Who is most at risk?
Certain groups are more vulnerable to serious HMPV infections, including:
Young children, particularly those under five years of age. Older adults, especially those with underlying health problems. Individuals with weakened immune systems, such as those receiving cancer treatment or living with chronic illnesses.
Preventive measures and response
To minimize the spread of HMPV, people should take preventive measures similar to those for other respiratory illnesses:
Wash your hands regularly with soap and water. Avoid close contact with sick people. Disinfect commonly touched surfaces. Wear masks in crowded or high-risk environments.
Health authorities in China and around the world are closely monitoring the outbreak, emphasizing the importance of vaccination campaigns for other respiratory diseases, such as influenza, and promoting public awareness of HMPV symptoms and prevention.
