Some kids may think that germs are bugs or other gross stuff. But germs are a nonmedical term for tiny organisms that can cause disease. To help explain germs in terms that your child can understand, Dr. Nieves suggests that parents tell their kids the following: “Germs are so small and sneaky that they creep into our bodies without being noticed. In fact, germs are so tiny that you need to use a microscope to see them. When they get in our bodies, we don't know what hit us until we have symptoms that make us feel sick.” CHOC’s Community Education department offers classes in Orange County. The class, “Germbusters” teaches kids how to protect themselves when someone coughs or sneezes. Learn more about CHOC’s no-cost community education classes.
