In medicine, transmission is the passing of a disease from an infected individual or group to a previously uninfected individual or group. The microorganisms (bacteria and viruses) that cause disease may be transmitted from one person to another by one or more of the following means:
Microorganisms vary widely in the length of time that they can survive outside the human body, and so vary in how they are transmitted.
