I am aware of some social media and mHealth interventions being implemented in Australia, but I had no idea of the enormity of the potential impact, and the range of ways in which these technologies can be used for HIV prevention, management, and improvement in quality of life for people who are HIV positive. It was mind-blowing to hear from one of the presenters that more than 1 billion people are active social media users, and how that reach can be optimised for the benefit of those at risk of or diagnosed with HIV. I found this fascinating, as like many clinicians, I have imagined social media to be helpful, but no idea how it can be harnessed, or whether there is actual evidence for its efficacy.
