What is CMV?

CMV, or Cytomegalovirus, is a common virus that can infect people of all ages. Once CMV is in a person’s body, it stays there for life. Most healthy adults and children who become infected will have no signs or symptoms and no long term effects from CMV. It can however pose serious risks to unborn babies if a pregnant woman catches it for the first time. Congenital CMV is when a baby has been infected before birth. It is one of the leading causes of hearing loss in children and one of the main causes of childhood disability.

Reducing the Risk

Avoid sharing cutlery and cups

Avoid putting things in your mouth that have just been in a child’s mouth. When possible, try not to share food, cups or cutlery, or put your child’s dummy in your mouth.

Wash any items which may have been in contact with a child’s saliva or urine.

Wash hands

Wash your hands after contact with a child’s urine or saliva. For example, try to make a habit of cleaning your hands after changing a nappy, feeding a child or wiping a child’s nose or mouth.

Wash your hands well for 20 seconds with soap and water. If you do not have access to soap and water, use hand sanitiser.

Avoid Kissing on the Mouth

Avoid getting saliva in your mouth when kissing a child. You can do this by trying to give more kisses on the head, together with a big hug.

Our Recommendations

Wash Hands


Risk reduction advice should be routinely given to pregnant women.



Produce and implement clinical guidelines and pathways for testing, improved diagnosis and management of cCMV.


Targeted Screening

Targeted screening for cCMV in children who fail a newborn hearing test to enable affected children to receive treatment much sooner.


Universal Screening

Universal screening for cCMV to enable affected children to receive treatment much sooner.



Invest in research to support clinical decision making.



Develop a vaccine to end CMV. Eradicate CMV once and for all.
