The World Health Organisation (WHO) has asked China for detailed information on the increase in the cases of respiratory illnesses and reported clusters of pneumonia in children across the country.
China has reported an outbreak of influenza-like illness, mostly among children. According to news reports, Chinese hospitals are "overwhelmed with sick children" who have symptoms of respiratory illness. The WHO said that Chinese authorities from the National Health Commission held a press conference on November 12, and reported an increase in respiratory diseases in the country. They attributed this to the lifting of the Covid-19 restrictions.
The Chinese authorities said that there is an immediate need for enhanced disease surveillance in healthcare facilities and community settings, as well as strengthening the capacity of the health system to manage patients.
On November 22, the WHO asked for additional epidemiologic and clinical information and also laboratory results from these reported clusters among children, through the International Health Regulations mechanism.
The WHO stated: "We have also requested further information about recent trends in the circulation of known pathogens, including influenza, SARS-CoV-2, RSV and mycoplasma pneumoniae, and the current burden on health care systems. The WHO is also in contact with clinicians and scientists through our existing technical partnerships and networks in China."
