(8,303 posts)It just isn't. Eventually we will have a transmission from one of these, and it will be random and not picked up (because case definition does not allow for testing). That transmission will generate more cases, and it's not clear if we will stop it then, because the odds that the cases derive from exposure in a health care setting are pretty damned good.
That is what is happening in Africa in this outbreak.
Your point about expense is almost insane. It costs 400-500K to take care of an Ebola case without risk to the HCW. Quarantine costs are miniscule compared to that.
They've used quarantine for household members very successfully in Africa to stop transmission. Quarantine does work.
One nasty thing we have is that the virus is more persistent at lower ambient temps. Wipe your runny eyes and touch the door handle, and you may leave viable virus for three hours to perhaps three days.
You seem to be living in a fantasy world. A very low-risk event becomes a high risk event through the multiplication tables. The risk of casual transmission through surface to surface contact here is probably on the order of 1%. Direct contact between household members was calculated about 15% in Africa.
So because Duncan's contacts didn't become ill, you are assuming that proves it doesn't happen - and you are wrong. Get five of those and it will happen.
Get 1000 very low risk exposures and you get a non direct contact transmission. This is just a numbers game.
