What are the symptoms of infectious diseases?
Serious infectious diseases can cause severe illness in children. Even if treated, some of these diseases can have life-long effects on the children who catch them.
It is useful for all parents to know how to recognise the early signs of these diseases so they can get help for their children, if needed.
If you decide not to vaccinate your child, they will be at increased risk of catching an infectious disease, and of getting seriously ill.
