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.
What is a social problem? A social problem is a condition that at least some people in a community view as being undesirable. Everyone would agree about some social problems, such as murders and DWI traffic deaths. Other social problems may be viewed as such by certain groups of people. Teenagers who play loud music in a public park obviously do not view it as a problem, but some other people may consider it an undesirable social condition.
