"Health communication has much to celebrate and contribute. The field is gaining recognition in part because of its emphasis on combining theory and practice in understanding communication processes and changing human behaviour. This approach is pertinent at a time when many of the threats to global public health (through diseases and environmental calamities) are rooted in human behaviour. By bringing together researchers and practitioners from diverse disciplines and adopting multilevel theoretical approaches, health communicators have a unique opportunity to provide meaningful input in improving and saving lives."
