This chapter discusses all the digital health technologies which generate continual streams of digital data about human bodies. Online searching for health and medical information and using health-related websites remain very popular pursuits. Google has acknowledged that searches for health information using its Search tool are among the most popular and the company has worked to facilitate user access to such information. Organisations such as the World Health Organization and the Centers for Disease Control and Prevention have social media accounts with large numbers of followers and have used these accounts effectively to disseminate health information to the public. Telemedicine employing digital technologies has been used in some countries since the early days of personal computing. Healthcare providers, government health promotion initiatives and commercial agencies take variable roles in supporting digitally engaged patienthood and digital personal health promotion. The chapter ends with a critical consideration of broader implications for ideas and expectations about appropriate patient behaviour and good citizenship.
