Impact of seasonal change on virus-rodent dynamics in Nigeria
Article in Current research in parasitology & vector-borne diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The zoonotic Lassa virus (LASV) is naturally maintained in rodents but commonly virulent in humans, killing thousands across West Africa annually. Human cases of Lassa fever surge during the dry season. In a hotspot for this disease, involving seven localities from Edo and Ondo states within Nigeria, we sought to depict how fluctuation patterns of LASV prevalence in rodents and levels of rodent infestation culminate in particularly heightened points of potential rodent-to-human transmission. We also explored how this variability may be driven by environmental and demographic factors. We determined active LASV infection by PCR and previous infection using an indirect immunofluorescence assay for IgG antibodies. Six out of the seven localities had active LASV infections, ranging between 3.7% (1/27) and 75.5% (37/49). In Ebudin and Ekpoma, where longitudinal sampling was conducted, prevalence differences were not statistically significant across locality, habitat, season, or year. Conversely, abundance peaked significantly indoors for
