Baylor College of Medicine, with collaborators across multiple institutions, published a wastewater-based method to detect HIV-1 in community sewage. The study, published in Nature Communications, uses a hybrid-capture genetic sequencing approach designed to dissect viral genomes from wastewater samples. The approach reframes wastewater surveillance from detecting pathogens broadly to characterizing viral sequences enough to potentially inform epidemiologic trends. Public health agencies could use such tools to complement clinic-based case detection, especially where testing access is limited. Industry interest will center on turnaround time, sensitivity in low-prevalence conditions, and how the method handles population mixing and sampling variability across communities.
