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.
HIV (Human Immunodeficiency Virus) is the virus that causes AIDS (Acquired Immune Deficiency Syndrome). The virus weakens a person's ability to fight infections and cancer. People with HIV are said to have AIDS when the virus makes them very sick and they develop certain infections or cancers. Because HIV weakens the immune system, people with AIDS are more likely to suffer health problems, including those of the skin. In fact, certain skin diseases may be the first sign that someone is infected with HIV.
