The theme of this book is germs - what they are, how to treat them and how to keep from letting them affect you. Lots of good information on such basic hygiene rules as not sharing towels, washing and covering cuts, and washing your hands - as well as washing raw food. We are told of the importance of covering mouth and nose when sneezing or coughing, how fever is treated, and how to take medicine. Going to the doctor and some of the tests he or she might do is minimally explained, as are occasional health checks and vaccinations. There are 2 pages of facts, a glossary, an index, and a list of further books to read. Good colour photos and large print help make the facts accessible, but I didn't quite believe the cheerful baby with a needle stuck in his arm!
