HMPV rise in China: ‘Not new or a looming pandemic threat’

The human metapneumovirus (HMPV) spreading in China is not a new virus, nor currently a looming pandemic threat, Director of the Allergy Immunology and Cell Biology Unit at the University of Sri Jayewardenepura Prof. Chandima Jeewandara said.

In a post on ‘X’ addressing the situation Prof. Jeewandara said that Chinese authorities and the World Health Organization (WHO) have not declared a state of emergency in response to a recent rise in respiratory infections in China, despite growing concern on social media.

“While HMPV is driving a rise in respiratory infections, it is neither a new virus nor a looming pandemic threat.”

Prof. Jeewandara noted that HMPV identified in 2001, is a well-documented virus that typically causes cold or flu-like symptoms, including cough, fever, and sore throat. In severe cases, it can lead to bronchitis or pneumonia, particularly in vulnerable populations such as young children, older adults, and individuals with pre-existing health conditions.

“Respiratory infections are common during winter and typically not a cause for alarm,” Prof. Jeewandara wrote. He noted that seasonal spikes in infections are expected, particularly as populations adapt to increased exposure to common pathogens following Covid-19 lockdowns.

Prof.Jeewandara also highlighted preventive measures such as handwashing and staying home when sick as critical to mitigating the spread of HMPV. While there is no specific antiviral treatment or vaccine for the virus, most cases resolve within a week with symptomatic care, he said.

“Routine testing is not necessary unless symptoms are severe or there’s an outbreak,” Prof. Jeewandara said adding that the University’s AIlergy, Immunology and Cell Biology Unit possess necessary reagents to carry out testing if necessary.

The Epidemiology Unit of the Ministry of Health yesterday said that it is paying close attention to the virus currently reported to be spreading across China.

The Epidemiology Unit said it will brief the media after conducting a proper study.
