Well, yeah. Have you been to a West African hospital? They do not serve meals or provide laundry. This makes them lively, homey places while the patient’s families prepare food over open fires and hang the boiled sheets between the trees. Changing bandages, hygiene, keeping the room clean, etc. is done by families. Latrines will be limited, and most patients will use basins which are emptied and cleaned by hand. All of this provides ample opportunity for infection. This would not happen in the US, where patients would be kept in isolation units, anything they make contact with will be destroyed or professionally disinfected, and families will not be having close personal contact. And in West Africa, the bodies of deceased patients are handed over to the family, which would not happen here.
In the current Ebola facilities, they are hosing down the protective materials to be re-used immediately. Doctors are working long shifts, making them prone to  forgetful actions like wiping their brow. In the US, doctors would likely work short shifts, maybe even less than 10 minutes. There would be little of the fatigue and mental/physical strain that is associated with healthcare worker infections. There is still opportunity for needle sticks and other failures that you can’t really do anything about, but right now most healthcare worker infections are fully preventable.
One problem is that early Ebola symptoms are non-specific. In West Africa, this is a problem because people may mistake Ebola for less serious diseases and almost anyone could be potentially exposed. But in the US there are relatively few people who will be possibly exposed-- just travellers, healthcare workers, and maybe some incidental contacts. You can bet each and every one of these will be tracked, and if one of them has a headache they are not going to write it off.
And if they do get a headache, they will be treated as a positive until they are proven otherwise-- which means they will be placed in isolation with full precautions. In West Africa, that is impossible. They cannot do that for everyone who has a headache.
Finally, survivors will be hospitalized until they are no longer infectious. This is not happening right now in West Africa, and there have been lost and escaped patients.
Literally no public health expert in the world thinks this is a threat to the US. These are people who get career advancement, funding and attention when they are working with a major, high-visibility threat. Think about how this story went from a side note to front page news after two Americans were infected. We care about stuff here. If Ebola was a serious problem for the US, these experts would likely become the biggest names in their field and awash with more funding that they could imagine for their dream programs. But, despite having every motivation in the world, they aren’t sounding the alarm. Why do you think that is?
