What is HIV?
Human Immunodeficiency Virus (HIV) is a retrovirus that targets the immune system and weakens people’s defense systems against infections and some types of cancer. Acquired Immunodeficiency Syndrome (AIDS) is the final stage of HIV infection. Without proper treatment, HIV can lead to AIDS, which is a life-threatening condition.1
HIV is primarily transmitted through unprotected sexual intercourse, contaminated blood transfusions, sharing needles or other drug paraphernalia, and from mother to child during pregnancy, childbirth, or breastfeeding. It is crucial to note that HIV cannot be transmitted through casual contact such as shaking hands, hugging, or sharing utensils.
Early detection and treatment of HIV are essential for managing the infection and preventing its progression to AIDS. Antiretroviral therapy (ART) is a combination of medications that can suppress the virus and help people with HIV live longer, healthier lives. Regular medical care and adherence to treatment are vital for successful HIV management.
HIV: A Deeper Look
HIV primarily infects a type of white blood cell called a CD4+ T cell, also known as a helper T cell. These cells play a critical role in the body’s immune system by coordinating and regulating immune responses. When HIV enters a CD4+ T cell, it uses the cell’s machinery to make copies of itself. These copies are then released from the cell and can infect other CD4+ T cells, leading to a progressive decline in the number of these vital immune cells.
As the number of CD4+ T cells decreases, the body becomes increasingly vulnerable to various infections and certain types of cancer. This weakened immune system is characteristic of AIDS, the most advanced stage of HIV infection. Opportunistic infections, such as Pneumocystis jirovecii pneumonia (PCP) and cytomegalovirus (CMV), and certain cancers, including Kaposi’s sarcoma and non-Hodgkin lymphoma, are common complications of AIDS.
Understanding the mechanisms by which HIV affects the immune system is crucial for developing effective prevention and treatment strategies. Ongoing research focuses on developing vaccines to prevent HIV infection, as well as new and improved treatments to suppress the virus and strengthen the immune system.
HIV: Prevention and Treatment
Prevention is paramount in combating HIV. Practicing safe sex, using condoms consistently and correctly, and avoiding sharing needles or other drug paraphernalia are essential preventive measures. Furthermore, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are effective strategies for preventing HIV infection in high-risk individuals.2
For individuals living with HIV, early diagnosis and prompt initiation of antiretroviral therapy (ART) are crucial. ART involves a combination of medications that work together to suppress the virus and prevent it from replicating. With proper adherence to treatment, ART can significantly reduce the amount of HIV in the body, known as viral load, to undetectable levels. This not only improves the health and well-being of people with HIV but also reduces the risk of transmitting the virus to others.
Ongoing research and advancements in HIV treatment have led to the development of new drugs and treatment strategies that are more effective, have fewer side effects, and require less frequent dosing. These advancements have significantly improved the outlook for people living with HIV, enabling them to live longer, healthier lives.
