WHO shared a statement in November 2023 that reveals an “official request” to China for “detailed information” on a reported increase in respiratory illnesses and clusters of pneumonia in children. The statement offers a timeline throughout November that explores the available information.
The timeline of information
WHO states that on 13th November 2023, during a press conference, Chinese officials from the National Health Commission reported an “increase in incidence of respiratory diseases” in China. This increase has been attributed to the lifting of COVID-19 restrictions and the co-circulation of known pathogens such as influenza, mycoplasma pneumoniae, RSV, and SARS-CoV-2. The authorities emphasised the need for enhanced disease surveillance in healthcare facilities and community settings, alongside strengthened health system capacity.
On 21st November 2023, media and ProMED reported “clusters of undiagnosed pneumonia in children in norther China”. Although it is unclear if these are associated with the overall increase in infections that was previously reported, this update led WHO to request additional epidemiologic and clinical information on 22nd November 2023. WHO also requested laboratory results from these clusters through the International Health Regulations mechanism.
“We have also requested further information about recent trends in the circulation of known pathogens…and the current burden on health care systems.”
WHO suggests that it is in contact with clinicians and scientists through “existing technical partnerships and networks” in China.
Advice
While WHO is seeking further information, it recommends that people in China “follow measures to reduce the risk of respiratory illness”. These include ensuring that recommended vaccination schedules are followed, keeping distance from people who are ill, staying home when ill, and testing and seeking medical care where necessary. Further measures include the use of masks “as appropriate”, ensuring “good ventilation”, and maintaining good hand washing habits.
Experts weigh in
Despite the lack of clarity, experts have already taken to social media to express concern and offer insights into the situation. For example, Dr Eric Feigl-Ding, epidemiologist and health economist, commented on X – formerly Twitter, that “many insiders” have suggested to him that Chinese doctors are “told by govt authorities to not report any numbers and not test patients & not report any tests”.
“This sounds eerily familiar.”
Dr Michael Oleson, epidemiologist, initially suggested that “the situation in China is looking more like Mycoplasma pneumoniae” before “betting” on “a new COVID variant”. He warned “watch for a global azithromycin shortage”.
