Abstract
The rapid spread of the Acquired Immune Deficiency Syndrome (AIDS) and its causative agent, the Human Immunodeficiency Virus (HIV), has posed people with difficult ethical questions. Philosophically, one of the most interesting problems is whether or not there is a right to remain in ignorance about one's own HIV infection.Being informed about a positive HIV test result has caused many people anguish and led some to suicidal thoughts. On these grounds a prima facte right not to know could be constructed. Paternalistic arguments have been put forward to refute the alleged right, but these arguments are invalid, as is shown in the paper.However, by a utilitarian argument it can be shown that the prima facie right to remain in ignorance is overridden by other people's rights not to be infected. With certain qualifications, even a non-voluntary testing programme for HIV is justifiable.
