For people who may have been exposed to HIV, knowledge is critical to making informed decisions about their future. An HIV test is a serious event with potentially serious outcomes. But no matter the result, the test provides vital information. A negative result is an opportunity to take…

An essential first step in caring for HIV-infected children is accurate and early diagnosis of HIV, early HIV testing, prompt return of results, and rapid initiation of treatment. Survival of HIV‐infected infants depends on a robust early infant diagnosis (EID) system that allows for tracking of…

Fungi are major contributors to the opportunistic infections that affect patients with HIV/AIDS. Systemic infections are mainly with Pneumocystis jirovecii (pneumocystosis), Cryptococcus neoformans (cryptococcosis), Histoplasma capsulatum (histoplasmosis), and 

Providing HIV testing at health facilities remains the most common approach to ensuring access to HIV treatment and prevention services for the millions of undiagnosed HIV-infected individuals in sub-Saharan Africa. We sought to explore the costs of providing these services across three southern…

The AIDSFree HIV Testing Services (HTS) Guidance Database has been updated with new guidelines from many PEPFAR priority countries. The database features HTS guidelines & policies on consent and confidentiality, testing algorithms & strategies, use of mandatory testing, quality assurance…

Rapid diagnostic tests (RDT) for HIV infection have high sensitivity and specificity, but in the setting of longstanding antiretroviral therapy (ART), can give false results that can lead to misinterpretation, confusion and inadequate management. The objective of this study was to evaluate the…

Rapid diagnostic tests (RDTs) are the primary diagnostic tools for HIV used in resource-constrained settings. Without a proper confirmation algorithm, there is concern that false-positive (FP) RDTs could result in misdiagnosis of HIV infection and inappropriate antiretroviral treatment (ART)…

This study describes the overall accuracy and performance of a serial rapid HIV testing algorithm used in community-based HIV testing in the context of a population-based household survey conducted in two sub-districts of uMgungundlovu district, KwaZulu-Natal, South Africa, against reference…

To mark the 9th IAS Conference on HIV Science, the Lancet journals have made a selection of content free that reflects some of the breadth and diversity of clinical, epidemiological, and operational HIV research produced by the tireless global HIV community. The content includes…

New strategies for HIV testing services (HTS) are needed to achieve UN 90-90-90 targets, including diagnosis of 90% of people living with HIV. Task-sharing HTS to trained lay providers may alleviate health worker shortages and better reach target groups.

We conducted a systematic review of…

Although individual HIV rapid diagnostic tests (RDTs) show good performance in evaluations conducted by WHO, reports from several African countries highlight potentially significant performance issues. Despite widespread use of RDTs for HIV diagnosis in resource-constrained settings, there has…

Rapid diagnostic tests (RDTs) account for more than two-thirds of malaria diagnoses in Africa. Deletions of the Plasmodium falciparum hrp2 (pfhrp2) gene cause false-negative RDT results and have never been investigated on a national level. Spread of pfhrp2-deleted 

This study aimed to evaluate the effect of storing commonly used rapid diagnostic tests above manufacturer-recommended temperature (at 37°C), and the accuracy of delayed reading of oral fluid kits with relevance to HIV self-testing programmes.

It concluded that erroneous results observed…

Background

Following HIV-1 acquisition, many individuals develop an acute retroviral syndrome and a majority seek care. Available antibody testing cannot detect an acute HIV infection, but repeat testing after 2–4 weeks may detect seroconversion. We assessed the effect of…
