Point-of-care human immunodeficiency virus (HIV) testing has increased diagnoses. New molecular tests are needed to detect early HIV infections, especially in resource-limited areas, to improve global health outcomes.

Area of Science:

  • Medical Diagnostics
  • Infectious Disease Epidemiology
  • Public Health

Background:

  • Serological point-of-care assays revolutionized human immunodeficiency virus (HIV) diagnosis over the past decade.
  • Increased HIV screening and result delivery have been achieved through point-of-care testing.
  • The evolving AIDS epidemic necessitates identifying acute (viremic, pre-seroconversion) HIV infections and differentiating "window phase" from serologically positive cases.

Purpose of the Study:

  • To address the need for advanced diagnostic methods in resource-limited settings.
  • To evaluate the utility of novel molecular diagnostic technologies for HIV detection.
  • To overcome technical, social, and operational challenges in implementing new HIV testing modalities.

Main Methods:
