The EATG aims to abide by the UNAIDS terminology guidelines to the greatest extent possible. According to the guidelines ‘people should never be referred to as an abbreviation, such as PLHIV, since this is dehumanizing. Instead, the name or identity of the group should be written out in full. Abbreviations for population groups can, however, be used in charts or graphs where brevity is required.’ As many abbreviations referring to people are widely used, we include them in this list.

Another useful resource is the HIV/AIDS Language Compendium of inter­na­tion­ally agreed terms, con­cepts, def­i­n­i­tions and evi­dence for rights-based responses.
