Describe the typical course of AIDS, from initial infection to death.
What will be an ideal response?
During the initial acute illness, CD4 levels fall sharply and HIV RNA levels increase; many infected people experience flulike symptoms during this period. Antibodies to HIV usually appear 3-8 weeks after the initial infection. During the asymptomatic phase that follows, CD4 levels (a marker for the status of the immune system) gradually decline, and HIV RNA levels again increase. Due to declines in immunity, infected individuals eventually begin to experience symptoms; when CD4 levels drop very low, people become vulnerable to serious opportunistic infections characteristic of AIDS. Modern treatment delays or slows the decline of the CD4 level. Chronic or recurrent illnesses continue until the immune system fails and death results.
