The US and many western countries have perfectly adequate centres were patients can be isolated and treated - you may be forgetting that Ebola and other viruses are also stockpiled as biological weapons in the west and you need doctors to have experience of treating such outbreaks if the unthinkable happens and war breaks out where biological weapons break out.
You said they have adequate facilities to isolate and quarantine in Africa.
So why are they being brought back to America ?
To study the virus ? They can ship live cultures of the virus internationally.
Still, no good answer to justify this
Anyhow, I think the original point I made is why - you can ship live cultures but understanding the disease / virus requires affected patients.
Einstein, "science without religion is lame, religion without science is blind."
Its not a new disease by any stretch.
And I think the majority of Americans wouldn't be terribly upset if these two people died in Zaire or the Congo.
I have little sympathy for them.
Look, Ebola can be prevented. Stop catching, slaughtering and eating fruit bats.
Im sure the people in these villages have been warned once or twice about the dangers of hunting these winged vermin BUT, they dont listen.
Nothing to do with reusing needles. Some medical equipment is being reused but it is also being disinfected. There is a lot of local expertise but not enough equipment available so a lot of health workers are dying.
Lassa fever transfers to humans through very specific aerosol processes i.e. the virus in rat urine on mud is carried in water vapour into the nostrils when humans hunt rats for food by sticking their heads down or near a rat hole (not a wise thing even when Lassa isn't a threat)
Ebola currently requires contact with liquids through very close contact. The chair of the WHO does sound the correct caution when she states that we must not allow the virus a chance to mutate.
"Apart from this specific situation, the general public is not at high risk of infection by the Ebola virus," she said.
"At the same time, it would be extremely unwise for national authorities and the international community to allow an Ebola virus to circulate widely and over a long period of time in human populations."
She also said that:
Constant mutation and adaptation are the survival mechanisms of viruses and it was important not to allow opportunities for them to deliver more surprises
Anyhow - I'm digressing - people need food, protein. It's not easy to suddenly find a new meat source. What would be more effective is to work on the culture of washing recently dead bodies by hand. That is the reason the numbers in West Africa are so high this time.
