Cytomegalovirus (CMV) is primarily transmitted from those who are infected to others (including unborn children) through:

  • Contact with bodily fluids like urine and saliva
  • Organ transplants
  • Blood transfusions
  • Breast milk
  • Exposure to bodily fluids during childbirth.

Although not highly contagious, CMV has been shown to spread through households and in daycares and other childcare facilities.
