Colorful, cartoonish illustrations accompany rhyming text introducing young readers to what germs are, where they hide, and the importance of washing hands and covering coughs.  In the back are a few extra pages with extra learning activities using the germ theme (patterning, counting, etc.).  Though the extra pages in the back seem a bit removed from the primary purpose of the book, the book does a good job of introducing young children to necessary health concepts in an engaging way. And it’s got a good sturdy binding, too.
