Kids may have a sore throat as a result of allergies or as a symptom of a cold. When a sore throat will not go away or when it produces soreness in your neck, it could be strep throat. Strep throat can develop when you share drinks or food with someone who has the bacteria present, or even when you breathe the air produced by a sneezing or coughing child who has the bacteria. Strep can only be treated by a doctor. This series, titled "First Facts. Health Matters," presents simple, brief explanations about how things that affect the young reader happen. Each title contains a hands-on activity that illustrates the principles discussed in the book or gives additional information. The glossary contains all the words that are in bold print throughout the text. An index and suggestions for further reading are included. This publisher maintains a web site, facthound.com, that directs children to resources chosen for age appropriateness. Each selection of resources is identified by typing in the book ID. Resources selected are then specific to age and the subject of the title. This management of resources is particularly helpful for this age group. All titles in this series have the same resource management page, and all titles are recommended for elementary classrooms and media collections.
