Our knowledge of HIV has increased significantly since the first identification of AIDS in 1981. There has been rigorous academic study of the way HIV behaves in the body, the way HIV is transmitted, the effect of HIV on the body, and the way people experience their HIV infection.
Scientific research on sexual transmission of HIV is persuasive. Using expert scientific evidence often introduces people to information about HIV they did not previously know, dispelling harmful, persistent myths. Using scientific research well can help convince people of the modern reality of HIV transmission risk, harms, and human behaviour.
