Inhaling aerosolized droplets from an infected person can definitely be the cause of an infection. But direct transmission by sticking viral laden fingers in your nose or eyes is probably more common. Actual studies have been done where they video record people and count the number of times per hour they stick their fingers in their nose or eyes. The actual incidence of finger in a nose or eye is many fold higher than what the study subjects recall. Most subjects did not the believe the researcher's count until they saw the recording of themselves. Many said they still didn't recall doing that. This is some tripe I could find quickly on Google. ccohs.ca Colds are really not very contagious, compared to other infectious diseases. Close personal and prolonged contact is necessary for the cold viruses to spread. The viruses must get into the nose where they can infect the nasal membranes. The virus must attach to nasal cells after which the viruses can multiply. Inhaling contaminated droplets produced when someone else coughs or sneezes may be one way to catch a cold. Cold viruses can remain infective even if they are outside the body for a few hours. You can catch a cold if you handle something that is contaminated with a cold virus and then stick your contaminated finger up your nose or rub your eyes. The cold viruses can reach the nose when you rub your eyes because the virus can be passed down the tear ducts that go from the eyes into the nasal cavities. .
