China is currently experiencing a widespread outbreak of Human Metapneumovirus (HMPV), which is overwhelming some hospitals and triggering public concern reminiscent of the COVID-19 pandemic.
Virus Characteristics
HMPV, first discovered in the Netherlands in 2001, causes respiratory infections with flu-like symptoms such as cough, fever, and breathing difficulty. Severe cases can lead to bronchitis or pneumonia, primarily affecting children under five, seniors over 65, and people with weakened immune systems.
Outbreak Updates
The Chinese CDC reported on January 9 that flu-like cases from the first week of 2025 showed a high positive rate for influenza, HMPV, and rhinovirus. Respiratory infection rates have continued rising since December 2024, especially in Jiangsu Province, where hospitals have seen a significant surge in respiratory patients.
Global Spread
The virus is not limited to China. Since January 2025, cases have also risen in India, including in Bangalore and Tamil Nadu, as well as Malaysia and Hong Kong.
Social Media Fueled Public Anxiety
Posts on social media have fueled public anxiety. A user claiming to work in a Jiangsu hospital wrote on December 25 about pneumonia cases with high death rates, though the post was soon deleted. Other users from provinces like Shaanxi and Liaoning shared stories of severe infections and crowded hospitals.
Health Officials’ Reassurance
Chinese authorities have strengthened public health measures and stress that while cases have risen, the current outbreak is milder than last winter. The World Health Organization (WHO) noted the infection levels remain typical for winter.
Experts’ Advice
Dr. William Schaffner from Vanderbilt University pointed out that HMPV, like other respiratory viruses, peaks in winter due to people staying indoors. He reassured that it is unlikely to cause a global outbreak and recommended measures such as avoiding crowded indoor spaces and wearing masks since no vaccine is available.
Dr. Du Chengzhe from Cheng Ching Hospital in Taiwan noted HMPV has a lower death rate than COVID-19 and usually causes mild cold-like symptoms. He mentioned past preventative measures like masking and distancing may have lowered immunity, contributing to the current surge.
Experts Warn Against Virus Mutation and Call for Transparency
Epidemiologist Dr. Ho Mei-hsiang urged China to be transparent about the virus to prevent the spread of misinformation and ensure proper monitoring for potential mutations.
Conclusion
The current outbreak of HMPV in China has raised concerns, but experts emphasize that it is not new and has a lower death rate. While the virus is spreading widely, it is essential to maintain basic precautions without panic. Staying informed and taking necessary precautions can help mitigate the spread of the virus.
