Why infection prevention in babies is important

Babies have immature immune systems. Even infections that are considered ‘mild’ in older children and adults can be life-threatening for babies.

One of the reasons that babies are more vulnerable to infections is that they have simply not been exposed to some common viruses. As they grow and get bigger, their immune systems will have had a chance to develop and will be more able to cope when they are exposed to bacteria, viruses, and other germs.

What we’re doing to prevent infections

Each year we host an Infection Prevention Week during October to show how we can all work together to keep babies safe from infection. We want to empower parents and carers to trust their instincts!

2025’s Infection Prevention Week will run from 19 – 25 October. We’ll be:

  • Raising awareness of the THANKS guidance (read below!)
  • Helping parents and carers explain their boundaries with well-meaning visitors.
  • Talking about the signs and symptoms to look out for, and when to visit a health professional.
  • Empowering parents and carers to trust their instincts, and what information to share with their health professional.

Keeping babies safe from infection is simple, and we can all do our bit. This animation explains how you can help to keep babies safe from infections by following the THANKS guidance: Think HandS and No KisseS.

  • Wash your hands: Always wash your hands before touching or holding a baby.
  • No kisses: People from outside the home should not kiss a new baby when they visit.
  • Don't visit if ill: Don't visit a new baby if you are ill or have been ill recently.
