用法
  1. in practice, there is little or no difference in meaning between contagious and infectious when applied to disease: both mean, roughly, ‘communicable’. There is, however, a difference in emphasis or focus between the two words. Contagious tends to be focused on the person or animal affected by the diseaseprecautions are taken with anyone who seems contagiouswhile infectious emphasizes the agent or organism which carries the disease: there are, for example, plenty of examples in the British National Corpus of infectious agent but none of contagious agent
