All activities and people whose primary purpose is to promote, restore or maintain health are part of the health sector1. This includes people from the general public who have a stake in their own health, healthcare providers (doctors, nurses, hospitals), payers (insurance companies), public health organisations (WHO, Universities, Schools), policy makers, technology specialists, medical device manufacturers and the pharmaceutical industry. The school setting is vital as it gives contact to almost all school-aged children over a longer period of time and schools can provide an ideal setting for the delivery of services from the health sector.
