Within these outbreaks, \u2018super\u2010spreading\u2019 dynamics play a critical role, where a small subset of individuals contributes to a disproportionately large share of secondary infections. To evaluate the relationship between human infectivity and viral load kinetics in Nipah virus infection and to define the role of the medical laboratory in identifying potential super\u2010spreaders, a narrative review was conducted by executing a systematic search across PubMed, Scopus, and ScienceDirect for peer\u2010reviewed literature published from 1998 to 2025. The qualitative synthesis demonstrated that NiV infectivity is highly dependent on specimen matrix efficiency and anatomical shedding patterns. Respiratory specimens yield the highest viral RNA copy numbers during the acute symptomatic phase, correlating strongly with active droplet transmission. Persistent real\u2010time RT\u2010PCR Cycle Threshold values below 25 (Ct\u00a0&lt;\u00a025) in respiratory samples serve as an indirect laboratory indicator of high\u2010risk shedders and should be interpreted alongside clinical and epidemiological findings. However, a comprehensive analysis indicates that super\u2010spreading is inherently multifactorial. Early identification via frontline molecular diagnostics remains the cornerstone of breaking NiV transmission chains. Although a standalone viral load threshold is insufficient to predict a spreading event on its own, the medical laboratory provides an essential risk profile by combining longitudinal Ct kinetics with clinical and exposure data. Strengthening regional laboratory infrastructure and deploying standardized point\u2010of\u2010care molecular assays in endemic, resource\u2010limited areas are urgent public health priorities.<\/jats:p>","DOI":"10.1002\/rmv.70194","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T09:59:43Z","timestamp":1786960783000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
