Is of possible for anyone in the u.s. to contract the ebola virus from just day to day contact ?

Not likely: Transmission from person to person is not from casual contact.

Really unlikely: Ebola is not present in the general US population. Ebola is spread by direct contact with an infected individual or the body and fluids of an infected person. So unless you are planning a trip to West Africa, you almost certainly cannot encounter Ebola. So ordinary contact in the USA is not going to get you infected.

Ebola Virus: Transmission is from someone who has signs of active infection via contact wi blood or bodily fluids or through contact wi contaminated objects. According to the World Health Organization – Ebola can be spread through body fluids such as sweat, blood, saliva, urine and stool. As of4 OCT 2014 - there were 3 cases treated in the US - so the odd's would be miniscule.
