JOHNSON CITY, Tenn. -

It's National Health Care Center week and to celebrate, the Johnson City Community Health Center hosted a health fair Saturday.

It focused on health and safety and was a way to look at the community and assess what they can do to keep people healthy.

Booths were set up Saturday to educate people on the many diseases out there. Some organizations included the Alzheimer's Association and Marsh Regional Blood Center.

It's an opportunity for health professionals to help people with diseases they're struggling with.

"We really want to have wellness care versus illness care. So if we take care of you while you're well, we'll prevent you from having chronic diseases," says Patti Van Hook from ETSU's College of Nursing.

Van Hook also tells News 5 obesity is the biggest disease challenging people in our area right now, and if they don't educate themselves, it could lead to worse diseases like diabetes, high blood pressure or heart disease.
