The World Health Organization says it has made an official request to China for information about a potentially worrying spike in respiratory illnesses and clusters of pneumonia in children.
The U.N. health agency cited unspecified media reports and a global infectious disease monitoring service as reporting clusters of undiagnosed pneumonia in children in northern China. In a statement late Wednesday, WHO said it was unclear whether those were linked to a rise in respiratory infections reported by Chinese authorities.
Outside scientists said the situation warranted close monitoring, but were not convinced that the recent spike in respiratory illnesses in China signaled the start of a new global outbreak.
The emergence of new diseases, particularly new flu strains or other viruses capable of triggering pandemics, typically starts with undiagnosed clusters of respiratory illness. Both SARS and COVID-19 were first reported as unusual types of pneumonia.
WHO noted that authorities at China’s National Health Commission on Nov. 13 reported an increase in respiratory diseases, which they said was due to the lifting of COVID-19 lockdown restrictions. Other countries also saw a jump in respiratory diseases such as respiratory syncytial virus, or RSV, when pandemic restrictions ended.
