Understanding HIV: A Review of Pathogenesis and Therapeutics

HIV (Human Immunodeficiency Virus) is a significant global health challenge that has led to the ongoing AIDS (Acquired Immunodeficiency Syndrome) epidemic. HIV primarily targets and weakens the immune system by infecting CD4 cells, T cells, and macrophages, thereby reducing the body's ability to fight off infections and diseases. The virus is transmitted through the transfer of blood, breast milk, semen, and vaginal secretions. HIV infection progresses through various stages, starting with acute infection, followed by clinical latency, and eventually leading to AIDS if untreated. While there is no cure for HIV, antiretroviral therapy (ART) has proven effective in managing the virus, prolonging the lives of those infected, and reducing the risk of transmission. Preventative measures, such as condom use and safe blood transfusion practices, play a crucial role in mitigating the spread of HIV. Despite extensive research, no vaccine is currently available to prevent HIV infection. Continued efforts in education, prevention, and treatment are essential to combatting this pervasive virus and improving the quality of life for those affected.
