Autor: Ernest L Yufenyuy, Mervi Detorio, Trudy Dobbs, Hetal K Patel, Keisha Jackson, Shanmugam Vedapuri, Bharat S Parekh

Publikováno v: PLOS Global Public Health, Vol 2, Iss 5, p e0000316 (2022)

We previously described development of a rapid test for recent infection (RTRI) that can diagnose HIV infection and detect HIV-1 recent infections in a single device. This technology was transferred to a commercial partner as Asante Rapid Recency Ass

Publikováno v: PLoS ONE, Vol 17, Iss 2, p e0262071 (2022)

Tests for recent HIV infection (TRI) distinguish recent from long-term HIV infections using markers of antibody maturation. The limiting antigen avidity enzyme immunoassay (LAg EIA) is widely used with HIV viral load (VL) in a recent infection testin

HIV incidence, viremia, and the national response in Eswatini: Two sequential population-based surveys.

Publikováno v: PLoS ONE, Vol 16, Iss 12, p e0260892 (2021)

With the highest HIV incidence and prevalence globally, the government of Eswatini started a substantial scale-up of HIV treatment and prevention services in 2011. Two sequential large population-based surveys were conducted before and after service

Publikováno v: PLoS ONE, Vol 11, Iss 5, p e0155498 (2016)

INTRODUCTION:A recent infection testing algorithm (RITA) that can distinguish recent from long-standing HIV infection can be applied to nationally representative population-based surveys to characterize and identify risk factors for recent infection

Publikováno v: PLoS ONE, Vol 11, Iss 4, p e0152327 (2016)

HIV incidence estimates are used to monitor HIV-1 infection in the United States. Use of laboratory biomarkers that distinguish recent from longstanding infection to quantify HIV incidence rely on having accurate knowledge of the average time that in

Recalibration of the limiting antigen avidity EIA to determine mean duration of recent infection in divergent HIV-1 subtypes.

Publikováno v: PLoS ONE, Vol 10, Iss 2, p e0114947 (2015)

Mean duration of recent infection (MDRI) and misclassification of long-term HIV-1 infections, as proportion false recent (PFR), are critical parameters for laboratory-based assays for estimating HIV-1 incidence. Recent review of the data by us and ot
