|
|
HIV-1
|
Retrovirus isolated and recognizd as the etiologic agen of aids
|
|
Window period
|
Time from infection with HIV until seroconversion detected on HIV antibody
|
|
Primary infection
|
4 to 7 week period of rapid viral replication immediately following infection; also know as acute HIV infection
|
|
Preventive education
|
Educate the public regarding safer sex with the correct use of condoms. Nonlatex condoms do not protect the HIV virus. The male should be circumsized to reduce the risk.

Viral set point
|
The body produces antibody molecules in an effort to contain the free HIV particles and assist in their removal. The remaining amount of virus in the body after this inital immune response is referred to as the viral set point, which results in a steady state of infection that lasts for years. The higher the viral set point, the poorer the prognosis

|
Latent reservoir
|
The intregrated HIV provirus within the CD4+ T cell during the resting memory state; does not express viral proteins and is invisible to the immune systme and antivrial medications
|
|
Category A
|
On average 8 to 10 years pass before a major HIV related complication. In this stage, patient feels well and have few, if any, symptoms. Good health continues because CD4+ remain high enough to serve immune defensive responses. 500

Category B
|
CD4+ gradually fall: 200-499. The condition is caused by HIV infection of a defect in cellular immunity. The condition is considered to have a clinical course or to require managemnet that is complicatated by HIV infection
