    the person or thing can still pass the illness on

  • contagious

    able to spread illness, especially by touch or closeness

Subject is a person, animal, or surface, not the disease itself. Often follows a treatment or waiting period ('now noninfectious', 'finally noninfectious'). Contrast with sense 1, where the word labels the illness.
