Syn : {

Usage :
Although often used as synonyms ,
originally these words were used in very diverse senses ;
but ,
in general ,
a contagious disease has been considered as one which is caught from another by some near contact ,
by the breath ,
by bodily effluvia ,
etc .;
while an infectious disease supposed some entirely different cause acting by a hidden influence ,
like the miasma of prison ships ,
of marshes ,
etc .,
infecting the system with disease .
In either case ,
a pathogenic microorganism is the direct cause of the disease .
This distinction ,
though not universally admitted by medical men ,
as to the literal meaning of the words ,
certainly applies to them in their figurative use .
Thus we speak of the contagious influence of evil associates ;
their contagion of bad example ,
the contagion of fear ,
etc .,
when we refer to transmission by proximity or contact .
On the other hand ,
we speak of infection by bad principles ,
etc .,
when we consider anything as diffused by some hidden influence .
