WHO asks China for more information about rise in illnesses and pneumonia clusters

World Health Organization requests details from China regarding respiratory illnesses and pneumonia clusters in children

The World Health Organization (WHO) has officially requested information from China regarding a concerning increase in respiratory illnesses and clusters of pneumonia in children. The organization cited media reports and a global infectious disease monitoring service that highlighted undiagnosed pneumonia clusters in northern China. While it remains unclear if these clusters are linked to a rise in respiratory infections reported by Chinese authorities, experts are calling for close monitoring to assess the situation. This article examines the potential implications of these developments and provides insights from experts in the field.

1: The significance of undiagnosed respiratory illness clusters

The emergence of new flu strains or viruses capable of triggering pandemics often begins with undiagnosed clusters of respiratory illness. Notably, both the Severe Acute Respiratory Syndrome (SARS) and COVID-19 were initially reported as unusual types of pneumonia. Therefore, the existence of undiagnosed pneumonia clusters in children raises concerns among global health authorities.

2: Uncertainty surrounding the recent spike in respiratory illnesses

While the recent spike in respiratory illnesses in China has attracted attention, experts are cautious about labeling it as the start of a new global outbreak. Dr. David Heymann, who led WHO’s response to the 2002-2003 SARS outbreak, suggests that discerning the cause of outbreaks is crucial. Genetic sequencing and isolating cases would be essential steps in determining the nature of the illnesses.

3: Potential causes of the spike in respiratory illnesses

Francois Balloux of University College London suggests that the current wave of disease in China is likely due to respiratory infections such as the flu, respiratory syncytial virus (RSV), or bacterial infections. Balloux points out that the first winter after the lifting of lockdown restrictions may have reduced children’s immunity to common bugs, leading to a significant wave of childhood infections.

4: WHO’s request for more information and China’s response

The WHO has formally requested more details from China about currently circulating viruses and any increased burden on hospitals through an international legal mechanism. This public request for information is a rare occurrence and highlights the seriousness of the situation. China’s National Health Commission has acknowledged the high incidence of infectious diseases among children and is working to enhance coordinated scheduling and implement a tiered diagnosis and treatment system.

5: Historical context and the importance of transparency

The request for information from China comes in the wake of previous instances where the country was criticized for withholding crucial details during public health emergencies. After the SARS outbreak in 2002, Chinese officials concealed patients from WHO scientists, leading to threats of closing WHO’s office in China. Similarly, during the early stages of the COVID-19 pandemic, China delayed sharing critical information with the WHO. These incidents highlight the importance of transparency and timely information sharing during global health crises.


While the recent spike in respiratory illnesses and pneumonia clusters in China warrants attention, experts believe it is premature to conclude that a new global outbreak is underway. Further investigation and information sharing between China and the WHO are crucial in understanding the nature and cause of these illnesses. In the meantime, WHO recommends that people in China follow measures to reduce the risk of respiratory illness, such as getting vaccinated, isolating if feeling ill, wearing masks when necessary, and seeking medical care as needed. The world will be closely monitoring the situation to ensure the timely identification and containment of any potential threats to global public health.
