This is an unusual report, and not just due to the information that has not been released.
- They've immediately sealed off an entire apartment building due to an illness of one resident.
- That illness is contagious.
- This resident was taken to a research hospital.
- This research hospital is now partially or completely quarantined.
So, the apparent meaning of all this, barring some bizarre miscommunication on the part of KCTV would be: whatever it is, it's highly contagious; it's unusual; and unnamed authorities have wasted absolutely no time in shutting down every place where this individual has been located for any length of time.
... and, no “Rockhill Research Hospital” turns up at all in a Google search.
