What the WHO, CDC et al are all trying to understand is that “RO” is now a completely meaningless concept.
The primary means of Ebola transmission in West Africa is no longer person to person.
It is _Ebola fomite contaminated environment_ to person.
This is a medical pandemic situation that is completely outside human experience.
There are no experts to listen too here. There are only people.
People who have greater or lessor degrees of front line experience and common sense versus death by fomite.
The PBS/Frontline website just posted the following:
Frontline: Ebola Outbreak - Sierra Leone
http://www.pbs.org/wgbh/pages/frontline/ebola-outbreak/
It lasts 27 minutes. Watch it.
Rolling fomite depositories. Keeping in mind the recently posted study that found a single fomite deposit on a door lever managed to transfer to 60% of total office staff in 120 minutes. Most any virus remains viable in that time
in order to stay viable, the virus needs to stay housed in moisture. this is how it can pass person to person by the air. water molecules from the lungs. a poorly ventilated room could hold the virus longer.
if the environment stays moist, the virus may remain contagious for a longer period of time. this would be how a an environment can become fomite.
taxi cabs being hailed by sick people trying to get to a hospital would be a prime location for such a situation. blood, sweat, and vomit could seep into the seats and be viable for a number of hours, spreading to every passenger that follows.
once it gets into the US, the only course of action will be to shelter in place. barricade yourself inside and wait it out. i would estimate a 4-8 week window would be required for it to burn itself out without the ability to spread.
What is 'RO'?
