An agent is described by its ability to cause disease and the nature and the severity of the dis-ease. The four major categories of agents are: (1) bacteria, (2) parasites, (3) fungi, and (4) viruses. Host resilience is a host factor. Infectiousness is the measure of the potential ability of an infect-ed host to transmit the infection to other hosts. Environmental factors facilitate the transmission of an infectious agent from an infected host to other susceptible hosts, such as a bug bite.
