Is there anything keeping the Ebola virus form entering North America?

and having in cause a major epidemic in one of the major cities? If there is, why? Explain it for me. If there isn't why not? explain that too. Please! Thank you!

oops, I meant from not form.

Nothing particularly keeping it from North America - there have been cases of Ebola in the U.S. - but they usually isolate the persons involved fairly quickly.

The good news is it is a fluid-borne virus - so unless you come in contact with the necessary body fluids of the infected, you will not get it. If it were instead, an airborne virus - and it got into a major city - boom, you could infect a large portion of the populace.

Or if a terrorist was clever enough to aerosolize infected blood and say get it into the air of a passenger jet - you could infect several hundred at once with it. And you can bet, if I'm clever enough to think that - someone much nastier could too.

Strangely - as horrible and quick as Ebola takes a person down (basically causing them to hemorrhage from the inside out), it has only a 70% mortality rate if I remember correctly (compared to AIDS, which has 100% mortality rate).

Although AIDS is controlled with medication - few have ever been rid of it once it has taken hold. They merely "live" with it - people have actually been lived through Ebola and been "cured".

no actual cases of ebola in the US. Was introduced to 2 facilities in which workers seroconverted but did not become infected. Go here:

scroll down to where do they occur. Report It

Yes. Americans.

Ebola is limited on a global scale due to its difficulty in spreading by airborne transmission and the period of time that the virus can use a living and contagious victim to spread compared to other infectious diseases.

This is just too long to write out. With the right circumstances, I anything can happen.

Sadly no there isn't unless you want to quarantine all peoples coming in from the African nations where it is most prevelant.
I have copied some informatio about it, then you will see why it would be nearly impossible to stop it from coming to America
Ebola haemorrhagic fever
Ebola virus, Filoviridae family, is comprised of four distinct subtypes: Za茂re, Sudan, C么te d鈥橧voire and Reston. Three subtypes, occurring in the Democratic Republic of the Congo (formerly Zaire), Sudan and C么te d鈥橧voire, have been identified as causing illness in humans. Ebola haemorrhagic fever (EHF) is a febrile haemorrhagic illness which causes death in 50-90% of all clinically ill cases. Human infection with the Ebola Reston subtype, found in the Western Pacific, has only caused asymptomatic illness, meaning that those who contract the disease do not experience clinical illness. The natural reservoir of the Ebola virus seems to reside in the rain forests of the African continent and in areas of the Western Pacific .

Ebola outbreak chronology


Transmission
The Ebola virus is transmitted by direct contact with the blood, secretions, organs or other bodily fluids of infected persons.
Burial ceremonies where mourners have direct contact with the body of the deceased person can play a significant role in the transmission of Ebola.
The infection of human cases with Ebola virus has been documented through the handling of infected chimpanzees, gorillas, and forest antelopes--both dead and alive--as was documented in C么te d'Ivoire, the Republic of Congo and Gabon. The transmission of the Ebola Reston strain through the handling of cynomolgus monkeys has also been reported.
Health care workers have frequently been infected while treating Ebola patients, through close contact without the use of correct infection control precautions and adequate barrier nursing procedures.
Incubation period: two to 21 days.
Its this incubation period that causes the problem.
With modern transport you can be anywhere in the world in 21 days before you show signs of the illness

Symptoms
Ebola is often characterized by the sudden onset of fever, intense weakness, muscle pain, headache and sore throat. This is often followed by vomiting, diarrhoea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding. Laboratory findings show low counts of white blood cells and platelets as well as elevated liver enzymes.
