In the development of any of its global guidelines, the World Health Organization (WHO) places importance on the values and preferences of the population or individuals that could be affected by the recommendations made within the guidelines. WHO has guidelines on the care, treatment and support for women living with HIV and their children in resource-con-strained settings, but these guidelines were published in 2006 and require updating. As an initial step in the updating process, WHO commissioned a global survey to listen to the voices of women living with HIV and determine these women’s sexual and reproductive health priorities. The main aim of the survey was to ensure that the values and preferences of women living with HIV would inform the guidelines from the very start of its development. The methods and key outcomes of the global survey are described and discussed below.
