My name is Dr Sindisiwe van Zyl. I use social media and digital technology to share health-related knowledge. We have seen a growing trend amongst South Africans and the larger global community to using the internet, and particularly social media platforms to communicate and share information. I realised that I could leverage my social media presence with medical knowledge aimed at helping people make better health decisions. As a medical doctor – with a particular interest in the Prevention-of-Mother-to-Child Transmission of HIV programme (PMTCT), I am determined to help create an HIV-free generation by imparting knowledge that empowers patients and health workers.

You can find me on Facebook at and on Twitter as @DocSindi. You can also read my HIV advice columns, Dear Doctor Sindi, in Bona magazine, and online at under HIV/AIDS Expert. Do tune in to the Health Hour every Wednesday between 1 and 2pm at
