China pneumonia: Everything we know about new outbreak of respiratory illness
Reports from local media say children's hospitals are "overwhelmed" with sick children, but Chinese authorities say a surge in sickness is a result of known illnesses circulating more widely after COVID restrictions lifted. Here is what we know so far.
China has seen an uptick in respiratory illness and clusters of undiagnosed pneumonia in children.
The World Health Organisation (WHO) has asked China for more detailed information about the increase in respiratory disease.
Look back to 5 January, 2020, and you'll find a statement from the WHO titled "Pneumonia of unknown cause - China".
It is therefore unsurprising that news of another mystery outbreak has set alarm bells ringing - but a WHO doctor has warned against jumping to conclusions and says getting more information is key.

What do we know about the mystery illness?
Northern China has reported an increase in influenza-like illnesses since mid-October, compared with the same period in the previous three years, according to the WHO.
Clusters of undiagnosed pneumonia in children in northern China have also been reported by groups including the Programme for Monitoring Emerging Diseases.

On 21 November, public disease surveillance system ProMed issued a notification about reports of "undiagnosed pneumonia".
The alert, based on a report by Taiwanese outlet FTV News, said children's hospitals in Beijing and Liaoning, 500 miles apart, were "overwhelmed with sick children".
"Many, many are hospitalised," Mr Wei, a Beijing citizen, told FTV News. "They don't cough and have no symptoms. They just have a high temperature (fever) and many develop pulmonary nodules."
In an editor's note, ProMed said: "This report suggests a widespread outbreak of an undiagnosed respiratory illness ... It is not at all clear when this outbreak started as it would be unusual for so many children to be affected so quickly.
"The report does not say that any adults were affected, suggesting some exposure at the schools."
What has China said about the outbreaks?
Chinese authorities said the rise in respiratory illness was partly due to COVID-19 restrictions being lifted.

Authorities also said the spike was due to known illnesses circulating, including flu, RSV, COVID-19 and mycoplasma pneumonia, a common bacterial infection that typically affects younger children.
The cold weather has also played a part, according to Chinese authorities.
(...)
What has the WHO said?
The WHO has made an official request to China for additional epidemiologic and clinical information as well as laboratory results from the reported outbreaks among children.
It has also requested further information about trends in the circulation of known pathogens referenced by Chinese authorities.

I wonder if this is the same as the uptick in cases of children with RSV that we had here in the U.S. over the past year or so, based on lack of immunity due to the isolation during the initial period of the covid-19 epidemic.
