Discussions about the increase in the elderly population have gained momentum in recent decades, as it is a reflection of advances in the field of health and the reduction in the birth rate. This change in age structure inspires caution, since the number of HIV/AIDS cases among the elderly is growing, requiring greater attention from public authorities and health professionals. This book has the following objectives: To identify nursing actions in the care and follow-up of elderly people living with HIV/AIDS in a municipal health polyclinic; To describe what measures have been adopted by nurses in the unit to help the elderly cope with this process of becoming ill; To analyse the perceptions of public health nurses about their role in relation to HIV/AIDS in old age.
