Keep in mind that viral hemorrhagic fevers (VHFs) are nothing new in the US. what happens in the United States with other fatal VHFs, that, like Ebola, are only spread via direct contact with bodily fluids and can be easily addressed in first world nations:
Hanta: http://www.cdc.gov/hantavirus/... [cdc.gov]
Marburg: http://www.cdc.gov/mmwr/previe... [cdc.gov]
Lassa: http://www.cdc.gov/media/relea... [cdc.gov]
Hanta is especially on point, as the US typically has dozens of cases -- and dozens of deaths -- each year, all of which are rapidly contained. The cases of "imported" VHFs, like has occurred with Marburg and Lassa, result in identification, isolation, and either the recovery or death of that person -- and that's the end of it.
I don't think you know what you're talking about. Saying "only spread via direct contact with bodily fluids and can be easily addressed in first world nations" seems to be a very dismissive attitude.
You can't declare them roughly equivalent to Ebola since they all cause types of hemorrhagic fevers, and therefor Ebola isn't anything special because it's "nothing new".
Hanta in particular. It isn't even transmitted from person to person, only from exposure to infected rodents. It isn't at all relevant to discussions on Ebola.
Lassa is also from exposure to rodents with 80% of cases asymptomatic, and from what I understand is much less likely to transmit person to person than Ebola.
Hanta and Lassa also have much lower mortality rates than Ebola.
Marburg seems to be especially rare, with one case ever of someone returning to the US with it, and it wasn't during an outbreak the size of the current one with Ebola, but is also to be taken seriously should there be an outbreak. I don't know the ease of person to person transmission with this one.
