Objective: To analyze the knowledge of elders regarding HIV/AIDS.
Methods: Descriptive, cross-sectional, quantitative study, with 457 elders from the Unit for the Care of Elders in Uberaba - Minas Gerais, lasting 3 months. The instruments used were the Mental State Mini-exam and a questionnaire on the human immunodeficiency virus for elders, together with frequency measures for their analysis.
Results: Most participants were female (74%), between 60 and 69 y/o (51%). The question with the most correct answers was about syringe/needle transmission (96.2%) and the ones with the least (45.3% and 49.6%, respectively) were regarding AIDS transmission through mosquito bites and whether a person with the human immunodeficiency virus always presents symptoms (49.6%). 88.2% of participants never use condoms.
Conclusion: The general level of knowledge can be considered good, responding to our goal. However, gaps in knowledge were identified due to the lack of campaigns aimed exclusively at such public, as well as to the lack of awareness of professionals.
