HIV and AIDS are related but distinct conditions. HIV is the virus that can lead to the condition known as AIDS. Understanding their mechanics, transmission, and effects is crucial.
The Human Immunodeficiency Virus (HIV)
HIV, or Human Immunodeficiency Virus, attacks the body’s immune system, specifically the CD4 cells (T cells). Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease.
HIV is typically transmitted through contact with infected bodily fluids, including blood, semen, vaginal fluids, rectal fluids, and breast milk. It is crucial to note that HIV is not spread through casual contact like hugging or sharing utensils.
Early diagnosis and treatment with antiretroviral therapy (ART) are critical. ART helps infected individuals maintain lower viral loads, which can keep HIV from progressing to AIDS. Regular medical check-ups and maintaining a healthy lifestyle are also essential for managing the virus.
Acquired Immunodeficiency Syndrome (AIDS)
AIDS, or Acquired Immunodeficiency Syndrome, is the final and most severe stage of HIV infection. In this stage, the immune system is severely damaged, and the body becomes vulnerable to opportunistic infections and certain cancers not typically seen in those with a healthy immune system.
The progression to AIDS varies among individuals and can take several years. With effective ART, individuals living with HIV can delay or prevent the progression to AIDS. It is identified when a person’s CD4 cell count drops below 200 cells per cubic millimeter of blood or when they develop one or more opportunistic infections.
Treatment is continuous for those diagnosed with AIDS, focusing on boosting the immune system, managing symptoms, and preventing further complications.
Transmission Pathways of HIV
HIV is primarily transmitted through specific high-risk behaviors or exposure events. Sexual contact remains the most common mode of transmission, particularly unprotected sex with an infected partner. Sharing needles or syringes with an infected person also poses a significant risk.
Mother-to-child transmission can occur during pregnancy, childbirth, or breastfeeding. However, with proper medical interventions, the risk can be greatly reduced. Healthcare settings can pose a risk if proper precautions are not taken, although this is rare in places with stringent protocols.
Standard preventive measures include practicing safe sex, not sharing needles, and ensuring safe blood transfusions. Pre-Exposure Prophylaxis (PrEP) is also an effective preventive strategy for those at high risk of HIV. Regular testing and early treatment are key to controlling the spread of HIV.
