Glossary of HIV/AIDS-Related Terms August 2015 • 8th Edition AIDSinfo is a U.S. government source for information on HIV/AIDS treatment, prevention, and research. a Terms and Definitions B C Absolute Contraindication d When a particular treatment or procedure should not be used under any circumstance because of the severe and potentially life-threatening E risks involved. F sEE rElAtEd tErM(s): AIDS Case Definition, AIDS Dementia Complex, Contraindication, Relative Contraindication G h Acanthosis nigricans A skin disorder characterized by velvety, light brown-to-black markings i that develop mainly in the folds of the body, such as in the armpits, J groin, and creases of the neck. Acanthosis nigricans can be an inherited condition or can occur as the result of an endocrine disorder, cancer, or K use of certain medications. l Acquired immunity M Immunity that develops during a person’s lifetime. There are two types of acquired immunity: active immunity and passive immunity. n sEE rElAtEd tErM(s): Active Immunity, Immunity, Passive Immunity o Acquired immunodeficiency syndrome (Aids) (Fig. 1) P A disease of the immune system due to infection with HIV. HIV destroys Q the CD4 T lymphocytes (CD4 cells) of the immune system, leaving the body vulnerable to life-threatening infections and cancers. Acquired r immunodeficiency syndrome (AIDS) is the most advanced stage of HIV s infection. To be diagnosed with AIDS, a person with HIV must have an AIDS-defining condition or have a CD4 count less than 200 cells/mm³ T (regardless of whether the person has an AIDS-defining condition). U sEE r El At Ed t Er M(s): A c u t e H I V I n f e c t i o n , A I D S C a s e D e n fi i t i o n , C h r o n i c H I V I n f e c t i o n , HIV Progression, Human Immunodeficiency Virus V W X y HIV/AIDS Glossary 1a B C d E F G Figure 1 h Acquired resistance i synonyM(s): Secondary Resistance J When a drug-resistant strain of HIV emerges while a person is on antiretroviral therapy (ART) for the treatment of HIV infection. K sEE rElAtEd tErM(s): Drug Resistance, Transmitted Resistance l Active immunity M Immunity that develops after exposure to a disease-causing infectious n microorganism or other foreign substance, such as following infection or vaccination. o sEE rElAtEd tErM(s): Acquired Immunity, Passive Immunity P Acute hiV infection (Fig. 1) Q synonyM(s): Primary HIV Infection r Early stage of HIV infection that extends approximately 1 to 4 weeks from initial infection until the body produces enough HIV antibodies to be s detected by an HIV antibody test.

U sEE rElAtEd tErM(s): Acquired Immunodeficiency Syndrome, Acute Retroviral Syndrome, Chronic HIV Infection, HIV Progression, Viral Load V W X y 2 HIV/AIDS GlossaryAcute infection and Early diseases research Program a (AiEdrP) B A federally funded research program that studies how HIV infects humans and how the disease progresses to AIDS. C Acute inflammatory demyelinating Polyneuropathy d synonyM(s): Guillain-Barré Syndrome E Acute retroviral syndrome F Flu-like symptoms of acute HIV infection that may appear approximately G 1 to 4 weeks after infection. Symptoms such as fever, headache, fatigue, and swollen lymph nodes can last from 1 to 4 weeks, and then subside. h During the acute stage of HIV infection, many, but not all, people will i have symptoms of acute retroviral syndrome. sEE rElAtEd tErM(s): Acute HIV Infection J Adenopathy K Large or swollen lymph glands. l sEE rElAtEd tErM(s): Lymph Nodes M Adenovirus n A group of viruses that use DNA as their genetic material and commonly cause respiratory and eye infections.

Q sEE rElAtEd tErM(s): Adverse Drug Reaction r Agammaglobulinemia s Total or near-total absence of gamma globulins in the blood. Gamma T globulins are a class of blood proteins that include most antibodies. Agammaglobulinemia may be due to certain genetic diseases or to U acquired diseases such as HIV/AIDS. sEE rElAtEd tErM(s): Gamma Globulin V W X y 4 HIV/AIDS GlossaryAgency for healthcare research and Quality (AhrQ) a A federally funded agency that produces evidence to make health care B safer, higher quality, more accessible, equitable, and affordable and that works with partners to ensure that the evidence is understood and used.
