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.

Infection Prevention Week 2026 will run from 19 – 25 October. This year’s theme is your baby, your boundaries’.

2026's theme is 'your baby, your boundaries;

Too many parents tell us they’ve felt awkward, embarrassed or even guilty for asking visitors to wash their hands or not to kiss their baby. This Infection Prevention Week, we’re reminding you that protecting your baby is never something you need to justify, and is always the right call. Your baby’s health comes before anyone else’s feelings. 

Setting boundaries to protect your baby from infection, particularly in the first few weeks of life, is so important. There are ways to do this kindly and confidently – and we’re here to help.

We’re encouraging families to set boundaries because:

  • Simple steps can help to keep your baby safe. Asking visitors to wash their hands before holding your baby, and asking visitors — or even strangers — not to kiss your baby, can help protect them from infection.
  • You never need to apologise for putting your baby first. You get to decide what's best for your baby, and that doesn't make you overprotective or overcautious.

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.
