New Delhi: China is currently grappling with a surge in cases of the Human Metapneumovirus (HMPV), a respiratory virus that is spreading rapidly across the country.
This comes after years of dealing with the COVID-19 pandemic, and the healthcare system is once again under strain, with hospitals reportedly overwhelmed.
Along with HMPV, multiple viruses, including influenza A, Mycoplasma pneumoniae, and COVID-19, are circulating, further adding to the pressure.

What is Human Metapneumovirus (HMPV)?
Human Metapneumovirus (HMPV) was first discovered in 2001 and belongs to the Pneumoviridae family, which also includes the Respiratory Syncytial Virus (RSV). While it was identified relatively recently, serological studies suggest that HMPV has been circulating among humans for over six decades and is present globally. It is known to cause respiratory illness in individuals of all ages, though it particularly impacts young children, the elderly, and those with compromised immune systems.
The symptoms of HMPV are similar to those of the common cold, including cough, fever, nasal congestion, and shortness of breath. However, it can also lead to more severe respiratory conditions, especially in vulnerable populations. In recent years, China has seen a spike in cases, raising concerns about the virus’s potential to cause more severe illness.
The Current Situation in China
As of early January 2025, multiple media reports and social media posts suggest that HMPV is spreading quickly throughout China, affecting individuals across a broad age range. Hospitals in many areas are reportedly overwhelmed, with emergency rooms flooded by patients presenting with symptoms of respiratory distress. Crematories have also been experiencing increased pressure, with some claiming a rise in sudden deaths linked to the virus.
There is growing concern about the simultaneous circulation of multiple viruses in the country. In addition to HMPV, influenza A, Mycoplasma pneumoniae, and COVID-19 are all reportedly circulating, further complicating the situation. Hospitals, particularly those that specialize in children’s care, are under significant strain, with rising numbers of pneumonia cases, some of which have been described as “white lung” – a condition characterized by severe, widespread lung damage.
Reports also indicate that the rate of HMPV infection has increased among children, with cases rising significantly among those aged 14 and below. Data from the Chinese Centers for Disease Control (CDC) shows a fluctuating but overall upward trend in positive cases of HMPV in this age group.
How HMPV Spreads and Who Is Most Vulnerable?
HMPV is primarily transmitted through respiratory droplets, which are expelled when an infected person coughs, sneezes, or talks. The virus can also spread through direct contact with contaminated surfaces or via person-to-person contact, such as handshakes. The incubation period for HMPV typically ranges from three to five days, after which symptoms start to appear.
While anyone can contract HMPV, it is particularly dangerous for young children, older adults, and individuals with weakened immune systems. People in these vulnerable groups are at a higher risk of developing severe respiratory conditions, including pneumonia, which can be life-threatening if left untreated.
Experts warn that HMPV can also spread quickly in crowded environments, which may contribute to its rapid transmission in areas with high population density like cities. Hospitals and healthcare systems may find themselves particularly challenged by a surge in respiratory illnesses, as both the number of patients and the severity of their conditions rise.
How to Prevent HMPV and Protect Yourself
As of now, there is no specific vaccine for HMPV, and the virus is managed primarily by treating the symptoms and supporting the respiratory system. Preventative measures include wearing masks, especially in crowded or public places, frequent handwashing, and maintaining good hygiene to avoid the spread of respiratory droplets.
Experts also recommend increasing immunity through a healthy lifestyle, which includes proper nutrition, regular exercise, and enough rest. However, people should be cautious when considering the use of antiviral medications. A recent warning from a Shanghai hospital highlighted that antivirals should not be used indiscriminately to treat HMPV, as they have limited effectiveness, and the virus often presents with symptoms similar to a common cold.

Global Presence of HMPV
While China is currently experiencing a significant outbreak of HMPV, the virus has also been detected in several other countries across the world. In 2023, HMPV cases were reported in the Netherlands, the UK, Finland, Australia, Canada, the US, and China, indicating its widespread nature. The virus tends to circulate more during the colder months, which may explain the uptick in cases observed at this time of year.
The Role of Health Officials and Ongoing Monitoring
Health authorities around the world, including China’s CDC, are closely monitoring the situation as it evolves. Increased testing and surveillance are crucial to tracking the spread of HMPV and managing the healthcare response. Experts continue to emphasize the importance of early detection and timely medical intervention to reduce the impact of severe respiratory illnesses caused by HMPV.
As the virus continues to spread, it is likely that more cases will be reported, and the situation could further strain healthcare systems. It remains crucial for individuals to follow public health guidelines, remain informed about the risks, and seek medical advice if they experience symptoms.
Understanding the HMPV Threat
While HMPV has been known for more than two decades, its recent surge in China has drawn attention to the potential risks posed by this virus. With hospitals under pressure and several viruses circulating at once, public health officials are urging caution. There is no vaccine for HMPV, but preventive measures, such as good hygiene and mask-wearing, can help reduce the spread. As health experts continue to monitor the outbreak, it is important for individuals to stay informed and take appropriate steps to protect themselves and others.
