AIDS – what is it exactly?Do you know what ‘AIDS’ stands for? ‘AIDS’ stands for Acquired Immunodeficiency Syndrome. AIDS occurs when HIV has severely damaged the immune system. When AIDS sets in, the body stops being able to fight off illnesses. People with AIDS become very thin as they lose their appetites and their bodies have trouble processing food. They are prone to catching many minor and major illnesses, such as colds, flu, pneumonia and cancer. At this stage a person’s life expectancy is short. Photo: © Yuri Arcurs, Shutterstock.com

The HIV virus is present in: bloodsexual fluids like semen breast milk HIV can be spread from one person to another through: unprotected sexual or anal intercourse unprotected oral sex contact with blood, e.g. when sharing needles in drug use breastfeeding.

World AIDS Day The red ribbon is worn as a sign of support for people living with HIV and is designed to raise awareness of the problem. Although it was originally designed in 1991 in New York to show support for people living with HIV/AIDS in the USA, it has become an international symbol of AIDS awareness since then. The artists who designed the symbol knew that it was important to have a simple, distinctive and non-copyrighted image so that it would be as effective and easily recognizable as possible.
