Globally, around % of deaths are caused by HIV/AIDS. This share is high but masks the wide variations in the toll of HIV/AIDS worldwide. In some countries, this share was much higher. On this interactive map, we see the share of deaths that resulted from HIV/AIDS across the world. Across most regions, the share was low: across Europe, for 1)Coinfection with other viruses/bacteria, and 2) nature of sexual networks. Per a study I'll try to find that modeled spread of HIV, a MASSIVE risk factor is presence of any blood in the genitals. Healthy vaginal secretions have much less virus in them than semen does, but blood has much more than semen SEX: The virus can be spread when a person who has the virus has unprotected sex (vaginal, oral, or anal sex) with another person. Remember: Do not have unprotected sex, always use a condom. PREGNANCY AND BREASTFEEDING: A mother who is HIV positive can pass the virus to her baby during pregnancy, while giving birth or when Mother-to-child transmission of HIV is the spread of HIV from a woman with HIV to her child during pregnancy, childbirth or breastfeeding The use of HIV medicines and other strategies have helped lower the rate of perinatal transmission of HIV to 1% or less in the United States and Europe. Most pregnant people with HIV can have vaginal How HIV is spread. Through vaginal or anal sex. Anal sex is riskier than vaginal sex. By sharing needles or syringes, such as when using drugs.

HIV stands for human immunodeficiency virus. HIV is a retrovirus that infects cells of the human immune system (mainly CD4-positive T-cells and macrophages—key components of the cellular immune system) and destroys or impairs their function. Infection with this virus results in the progressive depletion of the immune system, leading to In the acute stage of infection, HIV multiplies rapidly and spreads throughout the body. The virus attacks and destroys the infection-fighting CD4 Polarized HIV-1 release was initially observed in electron microscopy studies that reported accumulation of HIV-1 budding at sites of cell-to-cell contact (Phillips and Bourinbaiar ). These observations were consistent with the idea that direct cell-to-cell spread of HIV-1 via specialized cell contacts is much more efficient than infection with cell-free virus and is HIV-1 is divided into four groups, of which group M is the most prevalent. Subtype C, which belongs to group M accounts for almost half of all HIV-1 infections globally, with the highest concentration in southern Africa and India. The subtypes and groups are spread in various proportions across different world regions HIV can be transmitted from infected body fluids: Through sexual activity — through vaginal, anal, or oral sex (especially in the presence of oral disease such as ulceration or gingivitis). Vertically from mother to child — during pregnancy, childbirth, or through breastfeeding. By inoculation — via a contaminated needle, instrument HIV spreads via body fluids (semen and blood), sharing needles and through cuts. HIV cannot spread via touching someone, but can spread through things like unprotected sex and thus, is an example of a sexually transmitted infection. The main focus of HIV healthcare is prevention – i.e. educating people on the dangers of sharing needles or If you or a loved one is living with HIV, you may wonder how the virus can (and can’t) be spread from one person to [HOST] are plenty of myths and misunderstandings about how HIV is transmitted.
