Congenital Cytomegalovirus (CMV) is the most common infectious cause of birth defects.
About 1 out of 5 babies with congenital CMV infection will have birth defects or other long-term health problems, such as hearing loss. In 2011, Congress passed a resolution naming June “National CMW Awareness Month.” CDC takes this opportunity to increase awareness of congenital cytomegalovirus (CMV) among healthcare providers, pregnant women, and parents.
What is Congenital Cytomegalovirus (CMV)?
Congenital cytomegalovirus (CCMV) infection is the most common intrauterine infection in the U.S. and the most common cause of non-genetic sensorineural hearing loss in children. Most of the time, the disease is asymptomatic (85 to 90%).
The symptomatic congenital disease occurs most often after primary maternal infection in pregnancy. Although significantly less common, symptomatic CCMV carries a mortality risk of up to 7 to 12% in the early neonatal period. There is an increased risk of severe morbidity due to CNS damage, leading to neurodevelopmental delays, hearing loss, and vision impairment.
Asymptomatic disease is not entirely benign as 10 to 15% go on to develop long term morbidities. Despite these risks, there is poor awareness of CCMV among women of reproductive age.
There are simple and effective prevention measures you and your loved ones can take to mitigate the risk of CMV transmission during pregnancy. If you are pregnant or planning to become pregnant, talk with your doctor about CMV. Here are 5 Simple Tips to Help Prevent CMV:
Avoid contact with saliva when kissing a child
Wash your hands
Wash your hands often with soap and water for 15-20 seconds, especially after the following activities:
- Wiping a young child’s nose or drool
- Changing diapers
- Feeding a young child
- Handling children’s toys
Do not share a toothbrush
Do not put a pacifier in your mouth
Do not share food, utensils, drinks or straws
