HIV and AIDS social issues. In many regions, social issues increase the risk of HIV infection making it difficult to tackle the global HIV epidemic effectively. Certain groups of people are more affected by HIV than others. Sometimes this is because they engage in high-risk behaviours, while others experience stigma and discrimination that stops them from approaching HIV services.
AIDS, while continuing to be an important health issue, has evolved into a complex social and economic emergency. HIV primarily affects young adults, cutting a broad path through society's most productive layer and destroying a generation of parents, whose death leaves behind orphans, desocialized youth and child-headed households.
