So many kids are falling sick in China that a children's hospital said it saw 13,000 cases in a single day...WHO questions China about a mystery illness linked to pneumonia as hospitals fill with sick children

"Medical facilities in northern Chinese cities are warning that pediatric visits have swelled to new levels, compounded with the usual uptick in respiratory illnesses from winter setting in.

The Beijing Aviation General Hospital said on Friday that its pediatrics unit has been grappling with pneumonia and flu cases since the beginning of autumn, rising to a current 550 to 650 visits per day. That's 30 to 50% more than the same period in previous years, the hospital said."

"The World Health Organization (WHO) asked China for "detailed information" about a respiratory illness that's affecting children in the north of the country.

The organization requested "additional epidemiologic and clinical information" following reports of "undiagnosed pneumonia" spreading among children, according to a statement released on Wednesday.
The rise in cases had led to overcrowded clinics and emergency rooms, the South China Morning Post reported, citing social media posts. Hospitals in northern China appear to be "overwhelmed with sick children," NBC News reported."
