27 lip 2024 · HIV is transmitted through various body fluids, such as blood, amniotic fluid, breast milk, semen, pre-ejaculate, rectal fluids, and vaginal fluids. HIV can be transmitted through sexual contact, during pregnancy and delivery, and through fomites, such as reusable medical equipment or syringes.
Breakthroughs in the prevention of HIV important to public health include male medical circumcision, antiretrovirals to prevent mother-to-child transmission, antiretroviral therapy in people with HIV to prevent transmission, and antiretrovirals for pre-exposure prophylaxis.
20 lut 2023 · People living with HIV-2 infection can be found in most countries and regions globally, so it is an important consideration in patients with an AIDS-like illness . This topic will address the epidemiology, transmission, natural history, and pathogenesis of HIV-2 infection.
HIV (Human Immunodeficiency Virus) is composed of two strands of RNA, 15 types of viral proteins, and a few proteins from the last host cell it infected, all surrounded by a lipid bilayer membrane.
Fusion inhibitors (FI) Reverse Transcription: Inside the CD4 cell, HIV releases HIV RNA (its genetic material) and uses reverse transcriptase (an HIV enzyme) to convert HIV RNA into HIV DNA (to match the cell’s genetic material).
HIV is an approximately 100 nm icosahedral structure with 72 external spikes that are formed by the two major envelope glycoproteins gp120 and gp41. Two major types of the AIDS virus, HIV- 1 and HIV-2, have been identified. The major serological differences reside in the surface protein gp120.
