Fapon's HIV-P24: Enabling Precise and Early HIV Detection

As a result of global efforts to combat the AIDS epidemic, significant progress has been achieved worldwide. According to UNAIDS, while 39 million people still live with HIV globally, the number of new infections has declined by 38% to 1.3 million in 2022 compared to 2010. Despite these improvements, the battle against HIV persists, as only 86% of newly infected individuals are aware of their HIV status, and approximately 630,000 people worldwide have died from AIDS-related illnesses. The significance of prevention, diagnosis, and treatment in the ongoing fight remains paramount.


Detecting HIV Subtypes for Effective Diagnosis


HIV, known for its genetic variability, comprises of two main types: HIV-1, originating in the Congo Basin in Africa and causing 95% of global infections, and HIV-2, primarily found in West Africa with lower infectivity. This leads to diverse subtypes, numerous circulating recombinant forms (CRFs), and unique recombinant forms (URFs) globally, presenting challenges to the sensitivity and specificity of HIV testing. Therefore, developing diagnostic tests capable of detecting these variations is crucial for effectiveness.


Shortening Window Periods for Punctual Interventions


In addition to detecting various HIV strains, reducing diagnostic test window periods is crucial for timely treatment. The landscape of HIV testing has evolved significantly since the 1980s. Initially, individuals faced prolonged waiting periods, sometimes months, for detectable markers to appear. Advanced technologies now offer enhanced sensitivity, specificity, and shorter window periods through the latest generation test kits.


Notably, 4th generation test kits, detecting HIV-1 and HIV-2 antibodies along with the P24 antigen, are significantly advancing the detection window period to 2 to 3 weeks, enabling faster and more accurate diagnosis.

Moreover, the 4th generation test kit with P24 antigen testing is recommended for diverse scenarios, such as early detection for infants under 18 months of age, shortening the window period for adults in acute and high-risk phases and individuals using self-test kits, and evaluating responses in those participating in HIV vaccine trials.
