What is human metapneumovirus, are cases surging in China, and should we be worried?


Surging HMPV cases in northern China have prompted some online alarm but experts say the risk of another Covid-like pandemic is low. 

Human metapneumovirus (HMPV) is a respiratory disease that causes flu or cold-like symptoms, but can increase risks or lead to more serious complications like bronchitis or pneumonia, particularly among the elderly, young children, and immunocompromised people.

The disease is in the same family as respiratory syncytial virus (RSV), and has been around since at least 2001 when it was first identified in the Netherlands. Its outbreaks are concentrated during colder seasons.

 

Why is HMPV in the news?

Cases have been surging in northern China, particularly among children, according to local authorities. The country’s centre for disease control (CDC) has warned people to take precautions with health and hygiene, but has also pushed back against online claims of overwhelmed hospitals and fears of another Covid-like pandemic.

“Respiratory infections tend to peak during the winter season,” Chinese foreign ministry spokesperson Mao Ning said on Friday.
