"with symptoms consistent with both COVID-19 and common seasonal illnesses"

So 3 staff had gotten sick that flu season. Staff who work with infectious diseases and probably get every cough and cold checked out just in case. Seems pretty baseline average to me.

Its not that three got sick, that would be unremarkable. But three got sick so seriously as to seek hospital treatment.

That would be unusual. Given the proximity to the covid19 outbreak, there's a high probability that's the first known cases of covid19 - if confirmed.
