CMV in pregnancy: what every pregnant mum should know

Cytomegalovirus (CMV) is a common virus that can spread through young children's saliva and urine, often without symptoms. During pregnancy it can pass to the baby and sometimes cause hearing loss or developmental problems. You can lower the risk. Wash your hands with soap and water after nappy changes or wiping a child's nose or drool, and clean toys and surfaces. Avoid sharing food, cups or cutlery with young children, keep their dummy out of your mouth, and kiss their forehead instead of their lips.

On 13 October 2026, NSW announced $850,000 for CMV awareness and prevention, working with Cerebral Palsy Alliance. Guidance recommends information before pregnancy or during antenatal care, so the campaign should measure whether families get understandable advice early, including in their preferred language. These steps reduce risk but cannot remove it, and infection does not mean a parent did anything wrong. Ask your GP or midwife about CMV prevention and whether testing suits you.
