The virus is initially spread between person to person during close contact, most commonly by means of small droplets that come out by sneezing, talking, and coughing. The droplets usually fall onto things and not travel through air over long distances. Less ordinarily, individuals may get infected by contacting a contaminated surface at that point then touching their face.
