Our paper aims to analyze the conditions of effectiveness of prevention actions, in particular their limitations, and to propose new approaches for some of them. Generally speaking, these actions are restricted in their majority to messages drawn from epidemiologic reports. Beyond informing, some of these actions seek to reach people on an emotional basis, as on cigarette packages which "warn" smokers of smoking risks ("Smoking Kills") or TV ads showing the dramatic results of road accidents. However, the impact of such messages may unfortunately decrease over time. Other actions are based on a repressive approach which may be operative, as with the decrease in road deaths due to compulsory wearing of seat belts or the more recent introduction of radar detectors. However, a threshold of effectiveness is always reached after a certain time, which necessitates other strategies. With addictive behaviors for instance, repression, although necessary, cannot alone suppress behaviors due to identity related suffering. Approached from this angle, one aim of prevention might be to create the conditions for a form of questioning that would not judge people, but would concretely face them with their responsibility. To conclude, prevention is not an easy undertaking as the changes it seeks to promote require time and because people will really change only if they agree to do so. In Western societies characterized by mass culture and loss of symbolic references, adopting methods used in advertising to target personal behavior could offer a perspective. The aim would however be totally different since while advertising is designed to sell objects, prevention must propose material to build subjects. [ABSTRACT FROM AUTHOR]

Despite the enormous victory that has been recorded in decreasing significantly HIV-TB related mortality and morbidity in Sub-Saharan Africa, enormous challenges continue to obstruct proper and enviable control of these conditions. These range from prioritization, ethics, funding, drug resistance and research gaps. Resistance to these diseases could constitute key treatment and prevention challenges to health care systems and the international community if not handled appropriately and promptly. This paper presents key shortcomings of the current funding, management and research policies and highlights possible action areas to remedy this situation. [ABSTRACT FROM AUTHOR]
