The Center for Disease Control (CDC) is a place that helps people stay healthy and safe from things that can make them sick or hurt. The CDC has lots of people who study germs (tiny things that can make you sick), medicines, and how to stop diseases from spreading.
The CDC tells doctors and nurses all over the world what they can do to keep people from getting sick. They also help people who are sick or hurt to get better by doing research to find ways to cure them.
The CDC is like a big superhero team that works to make the world a healthier place!
