Madagascar is still among the rare states of low prevalence of HIV. The seroprevalence rate is nevertheless rising. The aim of this study is to show the current view of the epidemic, its future tendency, its economical and social impact on people and what measures to be taken at the national scale. In Madagascar, we can state by 1995 20 cases of notified AIDS and probably 130 cases of non-notified AIDS. Seroprevalence data are collected every year by the National Reference Laboratory STD/AIDS. But, they are insufficient to estimate the number of infected people. So, they had been completed by a serosurveillance study of AIDS and syphilis in middle of 1995 and at the beginning of 1996. Pregnant women, persons with STDs and prostitutes are been screened in the six biggest cities of the Island. Results show, not only a high prevalence of syphilis, but also indicate that now, we have about 5,000 seropositive people in the country. Besides, by the number of people with STDs, it is estimated that one million Malgasy adults risk to be infected. Based on estimates of the epidemic, be it the cases of a high scenario, (Kenya) or of a low one (Thailand) by the year 2015, the seroprevalence rate could represent 3% or 15% of adults. Demographic consequences of the epidemic will be serious, particularly if HIV spreads quickly. Nevertheless, it does not stop the increase of population. Therefore, there will be more infected people with the disease, especially young people between 15 and 49 years old. The increase of dead people will be serious. Social consequences of the epidemic (case of high scenario) will be gravely felt, in particular by the rise of the number of AIDS orphans. Tuberculosis outbreak can be observed too. This disease is already a serious problem in Madagascar. At last, the epidemic will bring with it a high increase of money spent on health and will have grave consequences on agriculture, industry and commerce. Nevertheless, Madagascar still benefit a big luck which is the prevention of the epidemic not to be exploded in a near future. For this, struggle against it is particularly effective on its start. In addition to counselling given to infected people and care-given to patients, means of prevention of AIDS contamination in all target groups must be set up quickly. It is about broadcasting information on AIDS, community education, controlling other STDs e.g. (importance of medicaments' program), promoting the use of condoms and screening HIV new cases. Only an urgent coordination of everyone's efforts can control the epidemic of AIDS.
