The WHO monitoring Chinese surveillance data since mid-October 2023, notes a rise in respiratory illnesses in northern China's children, attributed by the National Health Commission to lifted COVID-19 restrictions, cold season, and the presence of multiple pathogens.

WHO, utilizing the International Health Regulations, formally requested China to provide detailed epidemiological, clinical, and laboratory data on the escalating respiratory cases.

During a teleconference, Chinese health authorities disclosed a rise in pediatric respiratory cases since May, involving Mycoplasma pneumoniae, RSV, adenovirus, and influenza.

Chinese officials clarified that no unusual or novel pathogens or clinical presentations were detected, attributing the increase to multiple known pathogens.

Since mid-October, China has intensified surveillance, tracking trends in Influenza, ILI, RSV, SARS-CoV-2, Pneumonia, and SARI.

In China, WHO recommends minimizing respiratory illness risk by adhering to measures like receiving recommended vaccines, distancing from the sick, undergoing testing and seeking medical attention, wearing masks, and consistently practising handwashing.
