Dr Helen Bygrave
HIV/TB Advisor

Helen Bygrave is originally from the UK and worked in London as a hospital and primary care physician for ten years. In 2001 she took off to Uganda where a medical wake up call awaited her in an HIV clinic in Kampala, managing patients in the days before antiretroviral therapy was available. Four years later she signed up with MSF and by chance ended up in an HIV project, this time in Lagos, Nigeria. After seeing the amazing ‘Lazarus effect’ of antiretrovirals that were then available in the MSF clinic, she was bitten by the MSF/HIV bug and continued to work in HIV/TB projects in Myanmar and Lesotho over the next four years.

In 2010 she joined the Southern Africa Medical Unit and now provides technical support for HIV/TB projects across Africa. Her particular areas of interest are PMTCT, the introduction of less toxic antiretroviral therapies in resource poor settings and the introduction of viral load monitoring.
