This period is sometimes called asymptomatic HIV infection or chronic HIV infection. During this phase, HIV is still active but reproduces at very low levels. People may not have any symptoms or get sick during this time. For people who aren’t taking medicine to treat HIV, this period can last a decade or longer, but some may progress through this phase faster. People who are taking medicine to treat HIV (ART) the right way, every day may be in this stage for several decades. It’s important to remember that people can still transmit HIV to others during this phase, although people who are on ART and stay virally suppressed (having a very low level of virus in their blood) are much less likely to transmit HIV than those who are not virally suppressed. the end of this phase, a person’s viral load starts to go up and the CD4 cell count begins to go down. As this happens, the person may begin to have symptoms as the virus levels increase in the body, and the person moves into Stage 3.

There are an estimated 42 million people in the world living with HIV/AIDS, of which 19.2 million are women, and 3.2 million are children below 15 years of age. In 2002, there were 5 million newly infected HIV individuals and 3.1 million deaths relating to AIDS. In the United States, HIV/AIDS is more prevalent in African American and Hispanic communities than Caucasians.

Evidence for supplementation with selenium is mixed with some tentative evidence of benefit.[178] For pregnant and lactating women with HIV, multivitamin supplement improves outcomes for both mothers and children.[179] If the pregnant or lactating mother has been advised to take anti-retroviral medication to prevent mother-to-child HIV transmission, multivitamin supplements should not replace these treatments.[179] There is some evidence that vitamin A supplementation in children with an HIV infection reduces mortality and improves growth.[180]

Visible effects of HIV infection come in the form of disrupted lymph-node architecture. This disruption is temporal, and, at one point, lymph-node biopsy was considered as a form of staging the disease. [54, 55] The disruption of the follicular dendritic network in the lymph nodes and subsequent failure of normal antigen presentation are likely contributors to the disease process.

Because HIV infection produces a wide range of symptoms, the CDC has compiled a list of conditions regarded as defining AIDS. The physician will use the CDC list to decide whether the patient falls into one of these three groups:

There are currently six major classes of antiretroviral medications: (1) nucleoside reverse transcriptase inhibitors (NRTIs), (2) non-nucleoside reverse transcriptase inhibitors (NNRTIs), (3) protease inhibitors (PIs), (4) fusion (entry) inhibitors, (5) integrase inhibitors, and (6) CCR5 antagonists. These drugs are used in different combinations according to the needs of the patient and depending on whether the virus has become resistant to a specific drug or class of drugs. Treatment regimens usually consist of three to four medications at the same time. Combination treatment is essential because using only one class of medication by itself allows the virus to become resistant to the medication. There are now available pills that contain multiple drugs in a single pill, making it possible for many people to be treated with a single pill per day.

A few exceptional patients can control their HIV strain without treatment; they maintain normal CD4 counts and very low blood levels of HIV (long-term nonprogressors) or normal CD4 counts and undetectable blood levels of HIV (elite controllers). These patients may not require ART, but studies to determine whether treating them is helpful have not been done and would be difficult because there are few of these patients and they would likely do well not taking ART for long periods.

WHO recommends lifelong ART for all people living with HIV, regardless of their CD4 count clinical stage of disease, and this includes women who pregnant or breastfeeding. In 2016, 76% of the estimated 1.4 million pregnant women living with HIV globally received ARV treatments to prevent transmission to their children. A growing number of countries are achieving very low rates of MTCT and some (Armenia, Belarus, Cuba and Thailand) have been formally validated for elimination of MTCT of HIV as a public health problem. Several countries with a high burden of HIV infection are also progressing along the path to elimination.

The Ethics Committee of the American Society for Reproductive Medicine has said, “Health care workers who are willing to provide reproductive assistance to couples whose offspring are irreducibly at risk for a serious genetic disease should find it ethically acceptable to treat HIV-positive individuals or couples who are willing to take reasonable steps to minimize the risks of transmission.” (20).
