Yellow fever beyond the Amazon: surveillance challenges and the role of
Review in Lancet regional health. Americas, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Yellow fever virus (YFV) remains a major public health concern in tropical and subtropical regions of the Americas and Africa. Since late 2016, sylvatic yellow fever (YF) outbreaks and sporadic cases affecting both humans and non-human primates (NHP) have been recorded in Southern Brazil. These events raised concerns about viral persistence beyond the Amazon Basin, where YFV is endemic, and the potential reemergence of urban transmission. Neotropical NHPs are central to the ecology of sylvatic YF, but many aspects of their infection dynamics and species-specific roles remain poorly understood. Here, we revisit the role of NHP in YF transmission, focusing on marmosets, commonly found in urban and peri-urban areas in Brazil, as potential cryptic hosts of YFV. There is an urgent need to better understand and incorporate NHP ecology, host immunity, and vector dynamics into public health strategies to strengthen preparedness for arboviral reemergence, as the case of YFV.
