I know lots of people in the medical field. If I were a nurse at this point though, I would take it upon myself to read everything I could about ebola and about the regulations and safety measures health workers should be using.
The first nurses who got it get a pass (barely) because it was unexpected. Honestly at this point, if any nurse, doctor, etc. is contaminated treating someone in the US, it's their own fault. They can't blame the hospital anymore like nurses in Dallas are doing. It's their job, they should be doing follow up on their own. Plenty of jobs require that you continue learning pretty much forever and nursing is one of those jobs.
Funny thing is, even with the first nurses, if I was told I had to treat someone with an infectious, potentially deadly disease, I can't imagine myself taking someone's word on what to do or winging it like they did. I'm sure as hell I'd find out exactly what I had to be wearing and what the guidelines were with the CDC, which none of them did. It's ridiculous to me they aren't more accountable with all the "they never taught us this. They didn't prepare us. Etc" They knew what they were treating and they chose not to go get answers. Should the answers have been given to them? Yes, but that doesn't excuse not going to find them when they weren't provided.
Is that mean? At every job I've ever had, I'm expected to do and know things that people won't show or tell me. It's extra work than it could have been, but you do it cuz it's your job - and you'd think they'd be more inclined to do so considering lives are at stake. I blame them as much as I blame the hospital for not giving them proper training.
