Detailed explanation-1: -A few people have HIV that doesn’t progress to more severe symptoms or disease. They are referred to as nonprogressors. A small number of people never become infected with HIV despite years of exposure to the virus. These people are said to be.
Detailed explanation-2: -What is the HIV+ Long-Term Non-Progressor Study? A small group of people who are HIV positive remain healthy for long periods of time without medications. These people, known as Long-Term Non-Progressors (also referred to as Elite Controllers), have properties within their immune systems that control the virus.
Detailed explanation-3: -Long term non progressors (LTNPs) are individuals who are infected with HIV, but control the infection without antiretroviral therapy (ART). Vertically transmitted HIV infected children are now surviving into their adolescence due to ART. Very little is known about LTNP in vertically infected HIV positive children.
Detailed explanation-4: -long-term non-progressor (LTNP) – An HIV positive person whose CD4 count stays above 500 copies/mm3 with very low viral load for more than five years, without using ART. Some LTNPs have kept their CD4 count above 500 for more than 10-15 years without ART.
