RA 11166: Philippine HIV and AIDS Policy Act Flashcards
Which type of virus is HIV?
Retrovirus
It infects the cells of the human immune system, and destroys or impairs the cells’ function. It results in the progressive deterioration of the immunce system leading to immune deficiency.
Human Immunodefiency Virus (HIV)
HIV invades the _________ which are associated in making our immune response.
CD4+ T-Lymphocytes
The defiency of the immune system which stems from infection with HIV.
Acquired Immunodeficiency Syndrome (Stage 3 HIV)
Which stage of HIV can we acquire AIDS?
Stage 3
(+) HIV Serology
- CD4-Lymphocyte count below 200 cells/uL
- CD4-Lymphocyte percentage below 14%
Normal CD4-Lymphocyte count
500 - 1,400 cells
Is HIV/AIDS preventable?
Yes
Is HIV/AIDS curable?

The most effective way to prevent contracting HIV.
Abstinence
It refers to the laboratory procedure done on any individual to determine the presence or absence of HIV infection.
HIV Testing
Which presence are we looking for when performing HIV testing?
HIV antibodies
Positive result for HIV test
(+) Presence of HIV antibodies
Negative result for HIV test
(-) Absence of HIV antibodies
It refers to the period of time, usually two to six months during which an infected individual will test “negative” upon HIV testing but can actually transmit the infection.
Window Period
Window period for HIV
2 weeks - 6 months
ELISA stands for _________.
HIV Enzyme-Linked Immunosorbent Assay
- Screening Test for HIV
- Sensitivity > 99.9%
HIV Enzyme-Linked Immunosorbent Assay (ELISA)
- Confirmatory Test
- Specificity > 99.9%
Western Blot
- Screening test
- Simple to perform
HIV Rapid Antibody Test
- Predictor of HIV progression (HIV progression to AIDS)
- Risk of opportunistic infections and AIDS when <200
Absolute CD4 Lymphocyte Count
- Best test for diagnosis of acute HIV infection
- Correlates with disease progression and response to HAART
HIV Viral Load Tests
Nucleoside Reverse Transcriptase Inhibitors
Azidothymidine (Zidovudine)
Non-Nucleoside Transcripticase Inhibitors
Viramune (Nevirapine)
Protease Inhibitors
Norvir (Ritonavir)
