Reported clusters of respiratory illness children in northern China on WHO statement

Amidst the recent surge in respiratory ailments and notable pneumonia clusters among children, the World Health Organization (WHO) has formally requested intricate details from China.

During a media briefing on the 13th of November 2023, Chinese health authorities, representing the National Health Commission, disclosed a rise in the occurrence of respiratory conditions in the country. This escalation was attributed to the relaxation of COVID-19 restrictions and the prevalence of familiar pathogens, including influenza, mycoplasma pneumoniae (a common bacterial infection predominantly affecting younger children), respiratory syncytial virus (RSV), and SARS-CoV-2 (the causative agent of COVID-19). Emphasis was placed on the imperative need for heightened disease surveillance in healthcare facilities and community settings, coupled with fortifying the health system's capability to manage patients effectively.

Subsequently, on the 21st of November, media outlets and ProMED highlighted instances of unexplained pneumonia clusters among children in the northern regions of China. It remains unclear whether these occurrences are linked to the previously reported overall surge in respiratory infections or if they are distinct events.

On the 22nd of November, WHO formally petitioned for additional epidemiological and clinical insights, along with laboratory findings pertaining to the aforementioned clusters in children, utilizing the International Health Regulations mechanism. Further information was sought regarding recent trends in the prevalence of known pathogens such as influenza, SARS-CoV-2, RSV, and mycoplasma pneumoniae, in addition to an assessment of the existing strain on healthcare systems. WHO is also in active communication with clinicians and scientists, leveraging established technical partnerships and networks in China.

Starting from mid-October, northern China has witnessed an upswing in influenza-like illnesses compared to the corresponding period in the preceding three years. The country has established robust systems to capture data on influenza trends, influenza-like illnesses, RSV, and SARS-CoV-2, contributing to platforms like the Global Influenza Surveillance and Response System.

As WHO awaits the supplemental information, recommendations are extended to the populace in China to adopt measures that mitigate the risk of respiratory illnesses. These measures encompass adherence to recommended vaccinations, maintaining a safe distance from individuals exhibiting symptoms, staying home during illness, undergoing testing and seeking medical attention as necessary, appropriate mask usage, ensuring adequate ventilation, and regular hand hygiene.

WHO remains committed to furnishing timely updates on the evolving situation.
