Both the plague & Ebola have already been in the US. No, the President does not want to kill Americans; Bush cared little for US lives, Obama may have gone too far the other way, in terms of Iraq. And no Ebola, or plague in South America, there is an outbreak of TB in Virgina, but patient zero isn't an immigrant. Countries to the South of the US pose less risk than those to the north, because of climate; tropical diseases do not spread far in temperate climates.
Tell me about EBOLA in America!
Ebola Reston: Reston virus (abbreviated RESTV) was first described in 1990 as a new "strain" of Ebola virus (EBOV), a result of mutation from Ebola virus.[1] It is the single member of the species Reston ebolavirus, which is included into the genus Ebolavirus, family Filoviridae, order Mononegavirales.[2] Reston virus is named after Reston, Virginia, US, where the virus was first discovered.
RESTV was discovered in crab-eating macaques from Hazleton Laboratories (now Covance) in 1989. This attracted significant media attention due to the proximity of Reston to the Washington, DC metro area, and the lethality of a closely related Ebola virus. Despite its status as a level-4 organism, Reston virus is non-pathogenic to humans, though hazardous to monkeys;[3][4] the perception of its lethality was confounded due to the monkey's coinfection with Simian hemorrhagic fever virus (SHFV).[5]
MAPP Ebola: No details on what individuals, or which strain MAPP uses in California, work began 2003:
ZMapp uses an approach called passive immunotherapy. Instead of having a vaccine stimulate the immune system to make antibodies that attack the virus, passive immunotherapy simply supplies the antibodies to the patients.
For some infectious diseases, these antibodies are extracted from the blood of patients who have survived the infection and presumably have effective antibodies.
ZMapp instead consists of antibodies that are made by exposing mice to a key Ebola protein and harvesting their antibodies. Those antibodies are then genetically modified to make them more like human antibodies and therefore less likely to provoke an immune reaction if injected into people.
The company most likely flew Ebola in. Vaccine tests start next month, which means DoD has brought the virus in.
