A doctor treats sick people by identifying the symptoms and running diagnostic scans, but what lies behind such treatment methodologies? The common perception is that it is a doctor's qualification and experience. However, it still entails research and detailed efforts of people working in the public health sector. People often confuse healthcare and public health as they think it is all the same. Besides health is a common concern, a healthcare system focuses on facilitating the primary caregivers and patients in any health institution like hospitals.
