Global Cross-Border Migration and Secondary Transmission Patterns of Lassa Fever - Global, 1969-2025.
Article in China CDC weekly, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
What is already known about this topic?: Lassa fever has been increasingly transmitted from endemic West African regions via global migration; however, its macro-level transmission network and behavioral drivers remain uncharacterized. What is added by this report?: We constructed a historical cross-border transmission network that revealed two distinct modes: air-travel-dependent intercontinental spread and land-dependent regional spread. Secondary human-to-human transmission is rare across all scenarios and relies critically on robust local infection prevention and control. What are the implications for public health practice?: We recommend a shift from uniform border measures to precision- and scenario-based interventions. Enhancing targeted syndromic screening and local early warning capacities at the identified network hubs and bridge countries could optimize resource allocation and prevent outbreaks.
