Another group working contemporaneously with the Montagnier and Gallo groups was that of Dr. Jay Levy at the University of California, San Francisco. He independently discovered the AIDS virus in 1983 and named it the AIDS associated retrovirus (ARV).[138] This virus was very different from the virus reported by the Montagnier and Gallo groups. The ARV strains indicated, for the first time, the heterogeneity of HIV isolates and several of these remain classic examples of the AIDS virus found in the United States.[139]

In addition to the concern for new opportunistic infections, pre-existing infections can reactivate and cause significant disease in people with AIDS. The most important example on a global scale is that of tuberculosis, as reactivated tuberculosis can cause symptomatic disease with lower levels of reactivation.

Body fluid exposure – exposure to HIV can be controlled by employing precautions to reduce the risk of exposure to contaminated blood. Healthcare workers should use barriers (gloves, masks, protective eyewear, shields, and gowns) in appropriate circumstances. Frequent and thorough washing of the skin immediately after coming into contact with blood or other bodily fluids can reduce the chance of infection.

Effective chemoprophylaxis is available for many opportunistic infections and reduces rates of disease due to P. jirovecii, Candida, Cryptococcus, and MAC. If therapy restores CD4 counts to above threshold values for > 3 mo, chemoprophylaxis can be stopped.

Being HIV-positive, or having HIV disease, is not the same as having AIDS. Many people are HIV-positive but don’t get sick for many years. As HIV disease continues, it slowly wears down the immune system. Viruses, parasites, fungi and bacteria that usually don’t cause any problems can make you very sick if your immune system is damaged. These are called “opportunistic infections.” (Fact Sheet 500).  

Confidential testing for HIV infection: Testing should be offered routinely to adolescents and adults in virtually all health care settings. To facilitate routine testing, some states no longer require written consent or extensive pre-test counseling.

Among these three strategies, the opt-out approach is now recommended by most national organizations and federal agencies. For prenatal HIV testing, universal testing with patient notification and right of refusal was recommended by the Institute of Medicine to address clinicians’ concerns that pretest counseling and informed consent mandates for routine voluntary testing in pregnancy were too time consuming and, thus, reduced the likelihood of testing being offered (9). The Centers for Disease Control and Prevention, the American Academy of Pediatrics, and the American College of Obstetricians and Gynecologists (ACOG) endorse this approach (10, 11). Evidence suggests that this strategy may be acceptable to many pregnant women (12, 13). “To expand the gains made in diagnosing HIV infection among pregnant women,” the Centers for Disease Control and Prevention (14) has recently released, and ACOG (15) has adopted, recommendations to make HIV testing a “routine part of medical care” using a similar opt-out approach for all women at the time of routine health care visits.

The typical course of an infection with HIV is illustrated in Fig. 11.21. However, it has become increasingly clear that the course of the disease can vary widely. Thus, although most people infected with HIV go on to develop AIDS and ultimately to die of opportunistic infection or cancer, this is not true of all individuals. A small percentage of people seroconvert, making antibodies against many HIV proteins, but do not seem to have progressive disease, in that their CD4 T-cell counts and other measures of immune competence are maintained. These long-term nonprogressors have unusually low levels of circulating virus and are being studied intensively to determine how they are able to control their HIV infection. A second group consists of seronegative people who have been highly exposed to HIV yet remain disease-free and virus-negative. Some of these people have specific cytotoxic lymphocytes and TH1 lymphocytes directed against infected cells, which confirms that they have been exposed to HIV or possibly noninfectious HIV antigens. It is not clear whether this immune response accounts for clearing the infection, but it is a focus of considerable interest for the development and design of vaccines, which we will discuss later. There is a small group of people who are resistant to HIV infection because they carry mutations in a cell-surface receptor that is used as a co-receptor for viral entry, as we will see below.

This flu-like illness may be so mild it goes unnoticed, or in some people it may be quite severe and last for a few weeks before there is a return to seemingly normal health. Either way, this illness at the beginning of the infection is so similar to many other viral infections that the diagnosis of HIV infection may not be made at this time.
