Viral replication requires that reverse transcriptase (an RNA-dependent DNA polymerase) copy HIV RNA, producing proviral DNA; this copying mechanism is prone to errors, resulting in frequent mutations and thus new HIV genotypes. These mutations facilitate the generation of HIV that can resist control by the host’s immune system and by antiretroviral drugs.

Since the Bergalis case, many U.S. dentists, physicians, and surgeons with AIDS have begun disclosing their status to their patients. Faya v. Almaraz, 329 Md. 435, 620 A.2d 327 1993), illustrates the consequences of not doing so. In Faya, the court held that an HIV-positive doctor has the legal duty to disclose this medical condition to patients and that a failure to inform can lead to a Negligence action, even if the patients have not been infected by the virus. The doctor’s patient did not contract HIV but did suffer emotionally from a fear of having done so. The unanimous decision held that patients can be compensated for their fears. Although this case dealt specifically with doctor-patient relationships, others have concerned a variety of relationships in which the fear of contracting AIDS can be enough for a plaintiff to recover damages.
Greg Millett, a senior scientist for the C.D.C. for 14 years and a senior policy adviser for the Obama administration’s White House Office of National AIDS Policy, put it more candidly. “During the Bush years, the administration dropped all pretense that they cared about AIDS in this country,” said Millett, who is now the vice president and director of public policy at amfAR, the Foundation for AIDS Research. “The White House said H.I.V. is only a problem in sub-Saharan Africa, and that message filtered down to the public. Though the Bush administration did wonderful work in combating H.I.V. globally, the havoc that it wreaked on the domestic epidemic has been long-lasting.”
The major ethical principles that must be considered when formulating policies for HIV counseling and testing include respect for autonomy, confidentiality, justice, protection of vulnerable individuals, and beneficence to both the woman tested and, if she is pregnant, to her newborn as well. Individuals offering testing need to be mindful not only of the benefits of testing but also its potential risks because, if a woman’s test result is positive, she faces the possibility of being ostracized by her family, friends, and community or being subjected to intimate partner violence. In addition, although the overt stigma of HIV infection has been reduced over the past 20 years, the potential for job discrimination, loss of health insurance, and loss of housing still exists.
In 1991, the Visual AIDS Artists Caucus launched the Red Ribbon Project to create a symbol of compassion for people living with HIV and their carers. The red ribbon became an international symbol of AIDS awareness.51
HIV-1 entry, as well as entry of many other retroviruses, has long been believed to occur exclusively at the plasma membrane. More recently, however, productive infection by pH-independent, clathrin-dependent endocytosis of HIV-1 has also been reported and was recently suggested to constitute the only route of productive entry.

Human immunodeficiency virus infection and AIDs can cause a plethora of hematologic problems. Early on during HIV infection, immune thrombocytopenia is common as is the development of antiphospholipid antibodies. Anemia is the most common manifestation of HIV infection and is multifactorial due to both direct and indirect effects of the virus.12 Anemia is most often a hypoproliferative, low reticulocyte anemia due to anemia of chronic disease. Often, there is a blunted erythropoietin response. Coombs-positive autoimmune hemolytic anemia also occurs with increased frequency in HIV infection. Antiretroviral therapy often causes macrocytosis.
HIV disease becomes AIDS when your immune system is seriously damaged. If you have less than 200 CD4 cells or if your CD4 percentage is less than 14%, you have AIDS. See Fact Sheet 124 for more information on CD4 cells. If you get an opportunistic infection, you have AIDS. There is an “official” list of these opportunistic infections put out by the Centers for Disease Control (CDC). The most common ones are:
Most AIDS patients require complex long-term treatment with medications for infectious diseases. This treatment is often complicated by the development of resistance in the disease organisms. AIDS-related malignancies in the central nervous system are usually treated with radiation therapy. Cancers elsewhere in the body are treated with chemotherapy.
