od, bad, and sometimes truly ugly world of germs. Microbiologist Jennifer Gardy, who calls herself a disease detective, picks up her microscope to bring expert insight to the microbes that are all around us but are too small to see. Irreverent, playful, and contagious in all the best ways, It's Catching discusses a range of germs and the diseases they cause, from the common cold to food poisoning to the Ebola virus. Young readers will be enticed -- and pretty grossed out -- while becoming immersed in information about pus, bacteria, DNA, genomes, and more. They will learn how germs have shaped human history and also about the individuals who are working to hunt them down. Additional elements, like trading card-style profiles of a variety of diseases, a board game, and a detailed index, make this infectious read both useful and entertaining.
