The lessening in the severity of symptoms or duration of an outbreak of a disease.

A type of virus that, when not infecting a cell, stores its genetic information on a single-stranded RNA molecule instead of the more usual double-stranded DNA. HIV is an example of a retrovirus. After a retrovirus penetrates a cell, it constructs a DNA version of its genes using a special enzyme, reverse transcriptase. This DNA then becomes part of the cell's genetic material.

A uniquely viral enzyme that constructs DNA from an RNA template, which is an essential step in the life cycle of a retrovirus such as HIV. The RNA-based genes of HIV and other retroviruses must be converted to DNA if they are to integrate into the cellular genome. (See Retrovirus)

An open and competitive process for selecting providers of services (sometimes called RFA, or Request for Application).

Behavior or other factor that places a person at risk for disease; for HIV/AIDS, this includes such factors as male-to-male sexual contact, injection drug use and commercial sex work.

A laboratory technique that can detect and quantify the amount of HIV (viral load) in a person's blood or lymph nodes.

The part of the CARE Act that provides emergency assistance to localities (EMAs) disproportionately affected by the HIV/AIDS epidemic.

The part of the CARE Act that provides funds to States and territories for primary health care (including HIV treatments through the AIDS Drug Assistance Program, ADAP) and support services that enhance access to care to PLWH and their families.

The part of the CARE Act that supports outpatient primary medical care and early intervention services to PLWH through grants to public and private non-profit organizations. Title III also funds capacity development and planning grants to prepare programs to provide EIS services.

The part of the CARE Act that supports coordinated services and access to research for children, youth and women with HIV disease and their families.
