You raise and excellent point! I think they should most definitely display the various warnings of potential threats. Unfortunately I don't know much about the US medical system but I can tell you about the UK's NHS.
We have a system here where hospitals have to provide full disclosure of their MRSA status and appropriate regulations are then put in place to prevent spreading the infection outside, and within the hospital. These regulations even include bans on bringing flowers into the hospital and are very strict. There was even a ban of sitting on hospital beds for visitors to help curb the spread.
Personally I try to avoid the hospital at all costs. I recently had my ears syringed where my left ear was the problem. I thought I may as well get them both done at the same time. The result I currently have a massive infection in the right one most likely because of the moisture left behind after the procedure.
I think although you have some unfortunate experience with staph infection, your immune system must be pretty bad ass to get over cancer twice. That is really awesome!
You may just be particularly susceptible to that particular form of infection, just like I seem to be particularly susceptible to every throat infection going. Interestingly though I have never had food poisoning or the flu even when those around me have and we all shared the same circumstances. Every cloud I suppose.
