Nationwide variation of snakebite incidence in Kenya: Community surveys as an integrated NTD approach.
Article in PLoS neglected tropical 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
introductionSnakebite envenoming is a neglected tropical disease (NTD) of public health concern in Kenya. Its true burden remains elusive with an over-reliance on health facility-based data and geographically limited community surveys. This study aimed to generate data on snakebite burden in Kenyan communities and to capture the variation in incidence rate across the country by integrating snakebite incidence questions into nationwide Mass Drug Administration (MDA) campaigns for other NTDs.
methodsA cross-sectional community survey was conducted, nested within MDA campaigns targeting trachoma, schistosomiasis and soil transmitted helminths. Data collection spanned from July 2022 to August 2023. Incidence rates per 100,000 person-years were calculated, and correlation between snakebite incidence and population density was assessed. Community survey data were compared to the reported snakebite cases in health facilities by the Kenya Health Information System (KHIS).
resultsA total of 13,117,754 individuals from 17 counties participated in the MDA surveys, representing 27.6% of Kenya's total population. Across these counties, 4,667 snakebite cases were reported over the previous year, with a slightly higher incidence rate among males (39.3 cases per 100,000 inhabitants) compared to females (32.2 cases per 100,000 inhabitants). County-level incidence rates varied, with Turkana County reporting the highest incidence rate (412.9 cases per 100,000 inhabitants) and Vihiga County recording the lowest (3.7 cases per 100,000 inhabitants). Discrepancies existed between health facility attendance reported by community members and numbers reported by KHIS.
conclusionIntegration of snakebite data collection with MDA campaigns allowed rapid and highly cost-effective data capture from a quarter of Kenya's population. The community data demonstrated considerable variation in incidence rates and discrepancies with hospital-based data. This informs resource allocation for treatment and prevention and emphasizes the need for robust integrated approaches to assess the burden of snakebite envenoming both in health facilities and communities.
