"Ebola virus is transmitted by close contact with a person who has symptoms of Ebola," the CDC explains. "Close contact is defined as having cared for or lived with a person with Ebola or having a high likelihood of direct contact with blood or body fluids of an Ebola patient. Examples of close contact include kissing or embracing, sharing eating or drinking utensils, close conversation (3 feet), physical examination, and any other direct physical contact between people. Close contact does not include walking by a person or briefly sitting across a room from a person."
