Geneva, January 10 – The World Health Organization (WHO) has confirmed that the recent increase in common respiratory illnesses across the Northern Hemisphere, including China, falls within the expected range for the winter season, with no unusual outbreaks or emergency health concerns reported.
Reports of surging cases of human metapneumovirus (hMPV) in China have drawn international attention, evoking memories of the early days of the COVID-19 pandemic. However, the WHO stated that it has been in contact with Chinese health authorities, who confirmed that their healthcare system is not overwhelmed, and no emergency responses have been activated.
Respiratory Illness Trends
According to Chinese data up to December 29, detections of hMPV, seasonal influenza, rhinovirus, and respiratory syncytial virus (RSV) have increased in recent weeks, particularly in northern regions of the country. Among these, influenza is the most commonly reported cause of illness.
“The observed increases in acute respiratory infections and associated pathogen detections in many countries in the Northern Hemisphere in recent weeks is expected at this time of year and is not unusual,” the WHO noted in a statement.
About hMPV
Human metapneumovirus (hMPV), a respiratory infection first identified in 2001, typically causes mild cold-like symptoms but can lead to hospitalization in rare cases among vulnerable populations, including the elderly, young children, and individuals with underlying health conditions.
“Almost every child will have at least one infection with hMPV by their fifth birthday,” said Paul Hunter, a professor of medicine at the University of East Anglia, UK. Hunter suggested that improved diagnostic tools may be contributing to increased reporting rates of the virus.
Global Trends
Countries like India and the United Kingdom have also reported rising cases of hMPV and other respiratory illnesses, consistent with seasonal patterns that occasionally strain healthcare systems.
“Overall, I don’t think there is currently any sign of a more serious global issue,” Hunter added, emphasizing that the trends reflect typical seasonal respiratory infection surges rather than a new or escalating public health crisis.
Preparedness and Vigilance
The WHO continues to monitor the situation closely, underscoring the importance of seasonal flu vaccinations and standard public health measures to mitigate the impact of respiratory illnesses during winter.
