Spoiler:

the mentioned super-staff infection is what did in my late wife. her immune system was already heavily compromised due to a failed liver. this said same staff was the last straw. there was nothing they could do to stop it and believe me they tried everything.

the biggest problem is, its incredibly easy to spread
