Okay, kiddo. Have you ever heard of doctors and nurses who work for the government? That's what the United States Public Health Service is.
They are a group of people who work to keep us healthy! They do this by helping to prevent diseases and providing medical care to people all across the country.
Just like how you get a checkup from the doctor, the Public Health Service checks up on lots of people to make sure they are healthy. They also help people who are sick, by giving them medicine or helping them get the care they need.
One of the most important jobs of the Public Health Service is making sure we don't get sick in the first place. They educate people about healthy habits like washing your hands, exercise, and healthy eating. They also do research to find new ways to keep us healthy and prevent diseases from spreading.
So, the United States Public Health Service is like a big group of doctors and nurses who work for the government to keep us all healthy and strong!
