Mystery child pneumonia outbreak reported in China hospitals

"Chinese hospitals have been “overwhelmed with sick children” as an outbreak of pneumonia escalates in cities across the country.....ProMed – a large, publicly available surveillance system which monitors human and animal disease outbreaks worldwide – issued a notification detailing a reported epidemic of “undiagnosed pneumonia” in children.

It was a ProMed alert in late December 2019 that brought a mystery virus later named Sars-Cov-2 to the attention of many doctors and scientists, including senior officials at the World Health Organization. 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.” Yahoo
