Airborne droplets from coughing, sneezing and speaking, are the primary, direct source. These droplets do not remain airborne very long, and depending on air circulation, settle down on nearby surfaces, were the virus survives for a longer period. Direct contact with these surfaces, promotes further spreading onto the next contact surfaces, hence hand washing comes into play.
At least, that's my understanding on the subject.
