Kids pick up germs all day, every day. Whether they are sharing toys, playing at day care or sitting in the classroom, whenever children are together, they are at risk for spreading infectious diseases.

Parents should play an active role in helping their kids stay healthy by taking extra precaution to minimize germs. Here are a few tips on how.

Spending just a few extra minutes each day tidying up your household can go a long way to keep your home germ-free and your kids healthy. Disinfect kitchen countertops after cooking a meal, and wipe down bathroom surfaces as well—especially if your child has been ill with vomiting or diarrhea. Doorknobs, handrails and many plastic toys should also be sanitized on a routine basis. Simply by disinfecting your home more regularly, and even more so when someone in your household has been ill, you can significantly cut down on re-infection.

Parents should set good examples for their children by practicing good hand washing and hygiene at home. Encourage your kids to cough or sneeze into a tissue rather than their hands. Children should also be taught not to share drinking cups, eating utensils or toothbrushes. If your school-aged child does become ill, it’s best to keep them home to minimize spreading the illness to other children in the classroom.

Finally, one of the easiest (and most effective) ways to prevent the spread of infection is by hand washing. At an early age, encourage your child to wash their hands throughout the day, especially:

The Centers for Disease control recommends washing hands for at least 10 to 15 seconds to effectively remove germs.

Parents can’t keep their kids germ-free entirely, but you can take extra precautions to help keep your environment clean. It’s also important to help your child understand the importance of good hygiene and thorough hand washing as a vital way to kill germs and prevent illnesses.
