【Infectious】 ,  【infective】  as applied to agents related to the causing of disease may be interchangeable and then mean capable of infecting or tending to infect.

【Infectious】 , however, is more often restricted to the technical and figurative senses expounded in the preceding article.

【Infective】 may be distinctively applied to matter and means potentially 【infectious】 . In extended use it preserves the implication of corruption, strong in infect but often absent in  【infectious】 .
