Moving and exploring

What happens when a child encounters bacteria?

As your child starts walking and exploring, they are likely to experience grazes and injuries. Tumbles are normal, as are the accompanying knee scrapes. A typical childhood scrape or graze creates an invitation for bacteria, but your child’s body will quickly start to fight against bad bacteria. Their immune system will spring into defence mode!

Learn here just how the body will work when it encounters bad bacteria. We’re making science easier for parents to understand. We decipher terms like patrol cells and macrophages, and explain what the bacteria is doing, and how your child’s body will respond.
