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.
