HIV infection research focuses on the study of Human Immunodeficiency Virus (HIV), a virus that attacks the immune system and can lead to Acquired Immunodeficiency Syndrome (AIDS). Researchers in this area investigate various aspects of HIV infection, including the mechanisms of viral transmission, the development of antiretroviral therapies, prevention strategies such as vaccines, and the impact of HIV on individuals and populations. The ultimate goal of HIV infection research is to develop effective treatments and interventions to control the spread of the virus and improve the quality of life for those living with HIV/AIDS.
