What's the actual difference between infectious and contagious diseases?
A doctor has provided 1 answer
They are similar: Infectious disease is caused by an organism or particle that may cause disease in a given circumstance. This may or may not be contagious (although many are). The degree of contagiousness (how easily does it spread) helps to qualify a contagious disease, like the flu.
