RSV (respiratory syncytial virus) is a common virus that infects the nose, throat and lungs. Almost all children catch it by age 2; it usually causes cold-like symptoms but can lead to bronchiolitis or pneumonia in young babies.
Key takeaways
- Babies under 6 months and those born early are at higher risk of severe illness.
- In many countries, babies can be protected by a vaccine given in pregnancy or an antibody injection.
- RSV spreads through droplets and on hands and surfaces.
What you can do
- Wash hands before holding your baby, and ask visitors with colds to stay away.
- Ask your doctor or midwife which RSV protection is available where you live.
When to talk to your doctor
Call your local emergency number if your baby is struggling to breathe, has pauses in breathing, or has blue or grey lips. See a doctor urgently if they are feeding much less than usual or have fewer wet nappies.
