Children are especially susceptible to colds and flu, partly because they are exposed to more germs at school or daycare, or from picking up random objects and less frequent hand washing. You can protect your child against germs by taking preventative actions. Encourage (and model) regular hand washing and good hygiene, such as sneezing or coughing into your elbow. Monitor family members for signs of illness and if sick, stay home. For more information, visit cdc.gov/flu.
