How dangerous is this virus?
Five years after the Covid-19 pandemic, China is facing a rise in Human Metapneumovirus (HMPV) cases, a respiratory virus. Various media reports and social media posts suggest the virus is rapidly spreading across the country, with some alleging that hospitals and crematoriums are overwhelmed by the influx of patients. Videos circulating online show crowded hospitals, with reports of multiple viruses, including Influenza A, HMPV, Mycoplasma pneumoniae, and Covid-19, contributing to the surge in respiratory illnesses. The rise in HMPV cases is said to be linked to an increase in sudden deaths, especially among people aged 40 to 80.
A post on X by the SARS-CoV-2 (Covid-19) handle indicated that China is experiencing a surge in several viruses, including Influenza A, HMPV, Mycoplasma pneumoniae, and Covid-19, leading to overwhelmed hospitals and crematoriums. It highlighted that children’s hospitals are particularly strained due to rising cases of pneumonia and ‘white lung.’ Additionally, data from the Chinese CDC in late December, reported by China’s state broadcaster CCTV, showed a fluctuating but increasing rate of positive HMPV cases among children aged 14 and under.
What is HMPV Virus?
Human metapneumovirus (HMPV) is a respiratory virus that presents symptoms similar to the common cold and flu. Although the infection is usually mild, it can result in serious complications like pneumonia, especially in infants, the elderly, and individuals with weakened immune systems.
Human Metapneumovirus (HMPV), discovered in 2001, is part of the Pneumoviridae family, which also includes Respiratory Syncytial Virus (RSV). Despite being identified recently, serological studies suggest it has existed in humans for over 60 years and is widespread globally. Human Metapneumovirus can cause respiratory diseases in all age groups, but young children, the elderly, and individuals with weakened immune systems are most at risk.
According to the US Centers for Disease Control and Prevention (CDC), symptoms include cough, fever, nasal congestion, and shortness of breath. Li Tongzeng, a chief doctor at Beijing You’an Hospital, noted that Human Metapneumovirus spreads through respiratory droplets, direct contact, or touching contaminated surfaces, with an incubation period of three to five days. Preventive measures include wearing masks, regular hand washing, and strengthening immunity. Experts advise against using antiviral drugs for treatment, as no vaccine exists for HMPV, and its symptoms are often similar to a common cold. In 2023, Human Metapneumovirus cases were reported in several countries, including the Netherlands, Britain, Finland, Australia, Canada, the US, and China.
