Per CDC (Centers for Disease Control), the first Ebola case in USA was found on 09/30/2014 in Dallas,Texas. US people scared but outbreak in unlikely.
Ebola epidemic in 2014 is the largest in history, it affecting multiple countries in West Africa. Ebola doesn't spread like a cold, influenza, or measles. Ebola virus isn't airborne. Instead, it's in a sick person's bodily fluids, such as blood, vomit, urine, semen or saliva. But the bodily fluid become contagious if the person start feel sick.
Some symptoms are easily confused with other illness, however: fever, headache, flu-like body-aches and abdominal pain if it's follow by the vomit, diarrhea and sometimes bleeding need to be monitored.
Just take your own precaution. Use sanitizer every time you touch a door knob or anything before you touch your face. Wash your hand frequently.
