According to the Centers for Disease Control and Prevention (CDC), about 1.3 percent of children aged 0-4 and 1.8 percent of children aged 5-11 have fair or poor health, and about 3.3 percent of children aged 5-11 missed 11 or more days of school because of illness, injury, or disability. These matters, along with environmental hazards, lack of physical activity, poor diet, and other dangers, create concern for the well-being of our nation's children. This sourcebook provides information about children's health and safety and how to protect your child from injuries, seizures, and fever.
