When it comes to the flu, children are especially vulnerable. More than 20 kids have already died from the flu this year.
Schools are doing what they can keep things as clean as possible with lots of hand washing, hand sanitizer and reminders of how to properly cover your cough.
Doctors say the best way is to cough into your elbow not into your hand.
Kids are more likely to use good hygiene when it's fun. For example, sing a song that lasts at least 20 seconds while washing hands, songs like the ABC's or the happy birthday song twice.
And talk to your child about recognizing symptoms.
If your kid appears to be getting sick, don't give them an ibuprofen and send them to school. Keep them home so the infection doesn't spread.
