Prevention for Parents/Pregnant People

CMV is preventable

What simple steps can reduce the risk of CMV in pregnancy?
  • Avoid contact with saliva by kissing a young child on the forehead instead of the lips
  • Wash your hands often with soap and water for 15-20 seconds
  • Do not share food, drinks, or eating utensils with young children
  • Do not put a child’s pacifier in your mouth
  • Clean toys, countertops and other surfaces that come in contact with children’s urine or saliva

If I have already had CMV, do I need to worry about getting it again?

CMV is a member of the herpes viruses so once you have been infected, it remains in your system, and can re-activate in the future. When someone catches CMV for the first time, it is called a primary infection. When someone who already has had the virus gets infected with another strain, or their current strain becomes active again, this is called a non-primary or secondary infection.

▪️ 1-4 out of 100 pregnant individuals will experience a primary CMV infection
▪️ 1 in 1000 pregnant individuals will experience a secondary CMV infection during pregnancy

Although it is more likely that the fetus will be affected by a primary infection, a secondary infection may still cause harm to the baby.

Does having a young child put me at a greater risk of acquiring CMV?

▪️ Pregnant individuals should avoid getting body fluids in their eyes, nose or mouth. One of the most common exposures is through contact with saliva or urine of young children who recently had the virus.

▪️ Research shows that people who work closely with small children in settings such as child care facilities or have other children in the home while pregnant may be at greater risk.

▪️ The Centers for Disease Control and Prevention states that the risk of getting CMV through casual contact, such as hugging, is very small.

▪️ CMV is very common among healthy children one to five years of age (one in three five year-olds are already infected), especially for those in daycare and preschool. Even though your toddler may seem healthy and does not appear to have any symptoms of being sick, it is possible for him or her to shed the virus for three to six months or longer.
