> In the wee hours of Dec. 31, 2019, CDC deputy chief Lo Yi-chun could not sleep and was scrolling his phone when an online post shared in a CDC chat group caught his attention.
> Quoting information from Chinese websites, the post that appeared on PTT, one of Taiwan's largest internet bulletin board systems (BBS), warned about the potential danger of a SARS-like disease that was spreading in the Chinese city of Wuhan.
> "The post came out (on PTT) at 2 a.m., and at 3 a.m., I saw it being shared on a chat group by another sleepless CDC doctor," Lo said at a press conference Thursday.
> Lo said the post immediately caught his eye because unlike other unsubstantiated online messages this one included a chest CT scan, a hospital test result and what appeared to be a screenshot of messages sent by a doctor to his colleagues, warning them of a highly contagious virus.
