An ''infectious disease'' is caused by a [[pathogen|pathogenic living organism]]. While all [[contagious disease]]s are infectious, not all infectious diseases are contagious from a host of one species to a host of another.
'''Infectious diseases''' are illnesses caused by germs which have entered the body.
 
Contagion may need to occur through an intermediate [[vector (biological)]]: unless there is direct blood-to-blood contact, for example, [[malaria]] is not contagious between humans. Malaria is transmitted when a mosquito bites an infected host, and, in biting an uninfected host, transfers infected blood.
