Health Education –HIV/Aids NotesHIV/AIDSHIV (human immunodeficiency virus) infection has now spread to every country in the world.Approximately 40 million people are currently living with HIV infection, and an estimated 25 millionhave died from this disease. The scourge of HIV has been particularly devastating in sub-Saharan Africa,but infection rates in other countries remain high. In the United States, approximately 1 million people arecurrently infected.Meaning of terms:HIVstands for the human immunodeficiency virus. It is one of a group of virusesknown as retroviruses. After getting into the body, the virus kills or damages cells of the body's immunesystem. The body tries to keep up by making new cells or trying to contain the virus, but eventually theHIV wins out and progressively destroys the body's ability to fight infections and certain cancers.AIDSstands for the acquired immunodeficiency syndrome. It is caused by HIV and occurs when thevirus has destroyed so much of the body's defenses that immune-cell counts fall to critical levels orcertain life-threatening infections or cancers develop.EpidemiologyKenya’s AIDS epidemic is extremely widespread. Over recent years, the annual number of AIDS-relateddeaths has been steadily increasing. In fact, the death rate has doubled since 1999. The infection rate is farhigher in urban areas and most new infections are occurring among youth, especially young women ages15 to 24 and men under 30. Statistics that illustrate the severity of AIDS within the country follow.Adult (15-49) HIV Prevalence Rate: 6.7%Adults living with HIV: 1,100,000Adults and children living with HIV: 1,200,000Cases on ARVs: 460,000Globally, 85% of HIV transmission is heterosexual. In the United States, approximately one-third of newdiagnoses appear to be related to heterosexual transmission. Male-to-male sexual contact still accounts forapproximately half of new diagnoses in the U.S.Intravenous drug usecontributes to the remaining cases.Because the diagnosis may occur years after infection, it is likely that a higher proportion of recentinfections are due to heterosexual transmission.Infections in women are increasing. Worldwide, 42% of people with HIV are women.HIV/AIDS TransmissionHIV is transmitted when the virus enters the body, usually by injecting infected cells or semen. There areseveral possible ways in which the virus can enter.Most commonly, HIV infection is spread by having sex with an infected partner. The virus canenter the body through the lining of the vagina, vulva, penis, rectum, or mouth during sex.HIV frequently spreads among injection-drug users who share needles or syringes that arecontaminated with blood from an infected person.
