ABSTRACT
The identification in January 1983 of human immunodeficiency virus's (HIV's) antigen structure opened the door to new means of controlling the spread of the epidemic, notably through the development of specific serotests. The use of these serological tests, which came onto the market in 1985, plays an important role in structuring attitudes and behaviour towards HIV risk for seropositive and seronegative individuals alike. The tests make it possible to identify infected individuals. They also provide, or should provide, a prime opportunity for giving personalized counselling for prevention. As a result, testing is a major public health tool.
