Data on the Size of the HIV Epidemic

Human immunodeficiency virus. A non-taxonomic and historical term referring to any of two species, specifically HIV-1 and/or HIV-2. Prior to 1986, this was called human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). From 1986-1990, it was an official species called HIV. Since 1991, HIV was no longer considered an official species name; the two species were designated HIV-1 and HIV-2.

Human immunodeficiency virus

An organism of a particular biological taxon that is the site of reproduction of an organism of a different taxon.

host organism

Host

Homo sapiens

A disease is a disposition (i) to undergo pathological processes that (ii) exists in an organism because of one or more disorders in that organism.

disease

Disease

A disease whose physical basis is an infectious disorder

infectious disease

Infectious Disease

A count of individuals in a population who meet the criteria of some case definition during some time interval.

count of disease cases

Case Count

A count of deaths in a population that is the number of deaths that occurred during a proper part of a reference temporal interval.

incident death count

Incident Death Count

A count of infections (process) that occurred in a population in a given temporal region.

count of infections in a population

Infection Count

viral Infectious disease

Viruses Infection

A count of cases in a population that is the number of individuals who come to meet the criteria of some case definition during a proper part of a reference temporal interval.

incident case count

Incident Case Count

A syndrome resulting from the acquired deficiency of cellular immunity caused by the human immunodeficiency virus (HIV). It is characterized by the reduction of the Helper T-lymphocytes in the peripheral blood and the lymph nodes. Symptoms include generalized lymphadenopathy, fever, weight loss, and chronic diarrhea. Patients with AIDS are especially susceptible to opportunistic infections (usually pneumocystis carinii pneumonia, cytomegalovirus (CMV) infections, tuberculosis, candida infections, and cryptococcosis), and the development of malignant neoplasms (usually non-Hodgkin lymphoma and Kaposi sarcoma). The human immunodeficiency virus is transmitted through sexual contact, sharing of contaminated needles, or transfusion of contaminated blood.

AIDS

A count of infections in a population that is the number of infections of a given type that occurred during a proper occurrent part of a reference temporal interval.

incident infection count

Incident Infection Count

 A count of simulated or physical individuals in a population.

Population count

Population Count

A Disease due to or propagated by sexual contact.

sexually transmitted disease

Sexually Transmitted Disease

A data set that is about either some mortality rate or the death events themselves of some individuals of a given population of a particular biological taxon.

mortality data

Mortality

age-stratified

Age-Stratified

A census that is the specific outcome of a population demographic survey.

population demographic census

Population Demographic

Minute infectious agents whose genomes are composed of DNA or RNA, but not both. They are characterized by a lack of independent metabolism and the inability to replicate outside living host cells.

Viruses

An organism of a particular biological taxon that is the bearer of an infectious dispositions towards an organism of a different particular biological taxon.

pathogen

Pathogen

A data item that is an aggregate of other data items of the same type that have something in common. Averages and distributions can be determined for data sets.
