Usage notesEdit
  • There are two forms of croup, one caused by the diphtheria bacterium which may be deadly if not cured, and the other, less severe, caused by viruses. The viral form was formerly called pseudocroup. Vaccines and antibiotics have nearly eradicated the diphtheritic form from developed countries, and now the term "croup" chiefly refers to the viral form.
