What is the cause of the enigmatic surge in childhood pneumonia cases in China?
- Category: News
Amidst the growing occurrences of pneumonia and ‘white lung syndrome’ in China, various Indian states, including Haryana, Tamil Nadu, Kerala, Uttarakhand, Rajasthan, and Karnataka, are exercising caution. These states have issued alerts to hospitals and healthcare personnel, urging heightened vigilance in managing any surge in respiratory illnesses.
The health department in Kerala has specifically instructed district medical officers to closely monitor cases of influenza-like illness (ILI) and severe acute respiratory illness (SARI) in hospitals. Additionally, the state has reissued warnings regarding H1N1 flu (swine flu) across different districts.
Responding to recent reports highlighting an increase in respiratory illnesses among children in northern China, the Haryana government has directed civil surgeons to intensify surveillance on ILI and SARI cases. China is currently contending with a notable rise in respiratory ailments, including pneumonia, particularly affecting children. The World Health Organization (WHO) stated last week that the surge in hospitalizations is attributed to common winter infections rather than the emergence of new pathogens. It is noteworthy that China is experiencing its first winter without COVID-19 restrictions since the onset of the pandemic in 2020, leading to an anticipated spike in infections.
Unusual Events of Pneumonia in China:
Epidemiologists find the high prevalence of pneumonia in China unusual. When COVID-19 restrictions eased in other countries, influenza and respiratory syncytial virus (RSV) typically drove spikes in illness. Seeking more information, including laboratory results and data on recent trends, the WHO requested details from China’s health authorities last week. This request followed reports from media sources and the Program for Monitoring Emerging Diseases, which highlighted clusters of “undiagnosed pneumonia.”
In a statement on November 23, the WHO acknowledged China’s attribution of the rise in hospitalizations since October to known pathogens such as adenoviruses, influenza virus, and RSV. However, the increase in hospitalizations of children, particularly in northern cities like Beijing, is mainly attributed to Mycoplasma pneumoniae, a bacterium causing ‘walking pneumonia.’ Typically a mild form of the disease not requiring hospitalization, it has disproportionately affected children this year.

The Expert’s Opinion:
Epidemiologist Benjamin Cowling from the University of Hong Kong sees this surge in respiratory infections as a typical ‘winter surge,’ possibly occurring earlier this year due to increased susceptibility resulting from three years of COVID measures.
Epidemiologist Benjamin Cowling’s observations regarding the ‘winter surge’ point to a broader phenomenon—a convergence of respiratory infections potentially exacerbated by the collective impact of prolonged pandemic-related measures. The three-year timeline of COVID-19 measures may have influenced population susceptibility, creating a scenario where respiratory infections gain traction slightly earlier than usual.
As the global community grapples with ongoing health challenges, lessons from different regions become invaluable. The collaboration between health organizations and the sharing of information serve as crucial components in fortifying the collective response to emerging health threats. The current scenario reinforces the importance of adaptable public health strategies that can respond swiftly to evolving patterns of illness, ensuring the well-being of communities worldwide.
