Connected Health is a practical introduction to network thinking in public health and healthcare. It shows how relationships, trust, support systems, and care pathways shape real-world outcomes, from disease spread and misinformation to patient recovery and healthcare coordination.Written in clear, accessible language, this book helps students, clinicians, and public health learners see the hidden structure behind health problems that often seem confusing or fragmented. Rather than treating health as a series of isolated events, Connected Health offers a different lens: one that focuses on connection, flow, and the pathways through which risk, care, and influence move.
