Background: HIV assays designed to detect recent infection, also known as “recency
assays,” are often used to estimate HIV incidence in a specific country, region, or …

The early period of infection with human immunodeficiency virus (HIV) has been associated
with higher infectiousness and, consequently, with more transmission events. Over the last …

Background Accurate and reliable laboratory methods are needed for estimation of HIV-1
incidence to identify the high-risk populations and target and monitor prevention efforts. We …

Background 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 …

Pathogen phylogenies are often used to infer spread among hosts. There is, however, not
an exact match between the pathogen phylogeny and the host transmission history. Here …

Background. Accurate testing algorithms are needed for estimating human
immunodeficiency virus (HIV) incidence from cross-sectional surveys. Methods. We …

Standard‐of‐care HIV pre‐exposure prophylaxis (PrEP) is highly efficacious, but uptake of
and persistence on a daily oral pill is low in many settings. Evaluation of alternate PrEP …

The incidence of human immunodeficiency virus (HIV) is the rate at which new HIV
infections occur in populations. The development of accurate, practical, and cost-effective …

Background A limiting antigen avidity enzyme immunoassay (HIV-1 LAg-Avidity assay) was
recently developed for cross-sectional HIV incidence estimation. We evaluated the …

Identification of recent HIV infection within populations is a public health priority for accurate
estimation of HIV incidence rates and transmitted drug resistance at population level …
