What is the HIV infection stages?

Attachment of the HIV virus to an uninfected CD4+ receptor Uncoating: contents of HIV's viral core emptied into CD4+ T cell DNA synthesis: reverse transcription produces a mirror image of the viral RNA and double-stranded DNA molecule Integration of viral DNA into host DNA Transcription of the inserted viral DNA to produce viral messenger RNA Translation of viral messenger RNA to create viral polyprotein Cleavage of the viral polyprotein into individual viral proteins that make up the new virus Assembly and release of the new virus from the host cell

EIA- antibodies are detected, resulting in positive results and marking the end of the window period Western period- also detects antibodies to HIV, used to confirm EIA Viral Load- measures HIV RNA in the plasma CD4/CD8- these are the markers found on lymphocytes. HIV kills CD4+ cells, which results in a significantly impaired immune system OraQuick- in home HIV test

Stages of HIV disease?

HIV asymptomatic (more than 500 CD4+ T Lymphocytes): Patients feel well and have few symptoms because CD4+ T-cell levels remain high enough to preserve immune defensive responses HIV symptomatic (200-499 CD4+ T Lymphocytes), AIDS: CD4+ T-cell level drops below 200 When the levels drop below 100, the immune system is significantly impaired Important for entitlements: housing, disability benefits and food stamps)

What are emotional and ethical considerations for someone with HIV?

What is transmission of HIV?

Transmitted by body fluids containing HIV or infected CD4 lymphocytes Blood, seminal fluid, vaginal secretions, amniotic fluid, and breast milk Most prenatal infections occur during delivery Casual contact does not cause transmission Breaks in skin or mucosa increase risk
