- Ebola spreads through physical contact with an infected person's bodily fluids. It doesn't have the pandemic potential of airborne diseases like the flu, where one person's sneeze can infect a boatload of people. As long as you don't touch the blood, sweat or saliva of someone who has Ebola, you're going to be fine.
- Airports are on the lookout for sick people, to stop Ebola patients from traveling to and entering other countries.
- Even if Ebola did sneak into America, it wouldn't lead to a major outbreak, because doctors and epidemiologists have the resources to stop it. Since it spreads through physical contact, doctors can put infected patients in isolation wards, and as long as the doctors wear gloves, protective suits and surgical masks, no one else gets infected.
- In Africa, fears about Western medicine are causing people to turn to witch doctors for a cure. This means that instead of reporting to medical centers, infected people are crossing borders and spreading the disease. Since Americans are accustomed to relying on Western medicine, that seems unlikely to happen if Ebola were to cross overseas.
