Aeresolized droplets definitely land on things, but the most likely vector of infection is inhaling the virus into the lungs. The mucous membranes are also a possible vector, so if you don't touch your eyes, nose, or mouth, you should be OK even if you have the live virus on your hands -- and then washing your hands with soap and water, as we've said, should kill any live virus that might be there. It could survive on paper or cardboard for up to 24 hours, so I would say roughly about the same for clothing that has been contaminated, so if you have someone who is immunocompromised and you enter an enclosed space like a store, you might want to change your clothes when you get home and put them right in the wash, but the virus really cannot become airborne again under normal circumstances.
