Nowadays, the most accessible technology among the most disadvantaged populations in the world remains the mobile phone. Statistics released by the International Technology Union (ITU) indicate that over the past 15 years, information and communication technologies (ICTs) have grown up in an unprecedented way, providing huge opportunities for social and economic development.
Nearly 5 billion mobile phones are connected worldwide and over 85% of the world population is now covered by cell phone networks of which two billion live in developing countries. A recent World Bank report noted that more Africans now have a mobile phone than have a toilet.
According to Van, service and care providers, researchers and national governments are excited at the opportunities mobile health (mHealth) has to offer in terms of improving access to health care, engagement and delivery, and health outcomes. mHealth is seen as one of the great opportunities at providing targeted interventions to poor populations living in remote areas.
