IMHO your "opinion" is very very humble indeed and belongs in the category of "uneducated careless speculation with a sensationalist bent".
It may have escaped your notice, but doctors who help out in West-African hospitals come into close contact with a constant stream of very ill people who are in the stadium where they really are contagious, every day for months at a stretch.
Their protective clothing prevents transmission in the vast majority (say 99,9%) of cases (something you can tell by the fact that we still have doctors left treating Ebola patients). The real danger comes when you take off your protective suit. That has to be done carefully so as not to touch the splatters of blood, muckus, tears, sweat etcetera that very ill patients secrete and if possible it has to be decontaminated first.
Now I'm sure your "humble" and uneducated opinion never has been schooled in elementary probability so you wouldn't understand things like P(contagion_after_100_days) = 1 - [P(no_contagion_after_1_day)]^100, but try it this way.
Playing the lottery every day makes it unlikely that you won't win a single prize.
And so it is with medical personnel who treat Ebola patient for months. They run a risk.
So it's no conspiracy (I can feel your incredulity and disappointment) and no case of "fsking idiots" (a term which I'd like to reserve for you personally).
It's easy to shout your (thoroughly humble) head off about stuff you don't understand, but it's not helping anybody and it stands in the way of a rational attitude towards Ebola.
P.S. there is absolutely nothing "insightful" about your post. On the other hand it's revealing. Revealing of a mindset that couples a penchant for conspiracy theories with a complete lack of understanding of risk and a disdain for plain ordinary everyday scientific commonsense that seems to have whizzed over your (so very humble) head.
