  2. HIV&U HIV-the three phases Acute phase Chronic phase AIDS

  3. Acute Phase • Start of an infection is viral replication and killing of CD4 T cells • Symptoms appear three weeks into phase such as: • Fever • Rash • Muscle ache • Within a week the immune starts to regain control

  4. The Early Stages of HIV Infection

  5. Chronic Phase • Maintenance of viral levels at a set point • CD4 T cells remain high but over time concentrations fall • Power shifts away from immune system, HIV skyrockets • Immune proliferates and new infections mark the signs of AIDS

  6. CD4 and HIV Levels in the Blood Stream After Infection

  7. AIDS • AIDS becomes lethal within a year or two • Patients survive HIV between 10 or 11 years but as it destroys the CD4 lymphocytes the virus gains access to the interior of the cells and causes death

  8. How CD4 Depletion Affects the Rest of the Immune System
