Table of Contents HIV symptoms which may present in acute HIV infection: These are nonspecific symptoms and can present with other infections; consequently, they are unreliable indicators of HIV infection.
Remember, there is no HIV cure.
HIV is the abbreviation for the human immunodeficiency virus, which causes the acquired immunodeficiency syndrome
HIV window period is the time from HIV infection until a HIV Test can detect any change. Within the HIV window period, the HIV Test would be negative. During this period, the HIV viral load is extremely high, thus making the person highly infectious.
References HIV Test
- 4 weeks after exposure, a negative 4th generation HIV ELISA Test "is very reassuring / highly likely to exclude HIV infection."
- 12 weeks after exposure, a negative 3rd generation HIV ELISA Test "would definitively exclude HIV infection."

HIV DNA test
- A PCR (polymerase chain reaction) NAT (nucleic acid test) for HIV-1 proviral DNA, therefore a HIV DNA Test.
- Method: Proviral DNA Polymerase Chain Reaction (Roche Amplicor HIV-1 DNA Test, V1.5) This test uses primers SK145 and SKCC1B to define a sequence of 155 nucleotides within a highly conserved region of the HIV-1 gag gene.
- Usually used for the early diagnosis of HIV infection in neonates born to HIV+ mothers. As maternal antibodies circulate in the child for several months, the HIV antibody test would be positive.
- Also used for early HIV diagnosis in adults.

Individuals are eligible for HIV PEP Treatment if all the following criteria are met:
Prompt antiviral therapy may reduce the risk of HIV transmission by as much as 80%.
- less than 72 hours has elapsed since exposure;
- the exposed individual is not known to be HIV infected;
- the person who is the source of exposure is HIV infected or has unknown HIV status;
- mucous membrane or non-intact skin was exposed to a potentially infectious body fluid;
For optimal efficacy, antiretroviral therapy should be started as soon as possible, ideally within 1 hour of exposure. So that you can remain HIV negative.
The medications and dosages are the same as those used for lifelong treatment of HIV patients. However, for HIV PEP treatment, it is taken for only a month.
