There are a few videos on Twitter, some are spurious to say the least - people literally 'dropping' in the street, which doesn't seem consistent with the symptoms. Yes, hospitals overrun, but given the Chinese reaction to the outbreak it will have caused panic. Most of those being treated in hospitals may be presenting with nothing more than a common cold.
The only thing that gives me pause for thought is that China is a secretive state. In all likelihood they are deliberately underestimating the numbers. Plus, Wuhan is apparently home to a testing facility where they were 'studying' the spread of Ebola and VARS. But that could well be fake news promulgated by the uninformed on Twitter.
I personally would take little notice of the Chinese-provided figures. I will look to more reliable sources.
