Theme Hospital reference?

[Felix Atagong]

Walking around in the Science Wing area I remarked hearing these reassuring messages through the speakers from time to time coming from a female announcer, things like 'keep your cyanide capsules ready' or 'do not exchange bodily fluids due to the virus infection',...

Obviously meant to be funny I think this is a direct reference to Theme Hospital (Bullfrog, 1997) where a same - soothing - voice said things like: Patients are reminded not to die in the corridors
Patients are asked not to vomit too much
and my personal favourite...
Patients are asked to be patient
(full list here)

(Have I been infected, or what?)
