1 min. readlast update: 02.01.2024

CMV spreads person-to-person via direct exposure to bodily fluids, including:

  • Urine
  • Saliva
  • Mucus
  • Cervical secretions
  • Blood
  • Semen
  • Breast milk

Daycare centers are one of the most common exposure settings for children. For adults, unprotected sexual activity is a typical cause of infection. An infected mother can transmit CMV to her fetus via the placenta or cervical secretions during birth.
