Mapping the COVID-19 pandemic in Burkina Faso: spatial patterns, socioeconomic factors, and public health implications.
Article in International journal of health geographics, 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
The first case of COVID-19 in Burkina Faso was reported in March 2020. As of June 8, 2025, Burkina Faso reported 22,114 confirmed cases and 400 deaths. However, few studies have investigated the spatiotemporal dynamics of pandemics within the national boundaries. This study provides a retrospective spatial analysis of COVID-19 transmission in Burkina Faso and identifies the key geographic drivers. Case statistics from March 2020 to December 2021 were sourced from the Directorate of Health Information Systems of the Ministry of Health. Covariates were identified through a literature review and retrieved from local and online resources. Spatial and temporal patterns were analyzed using ArcGIS Pro® 3.4.3. Hotspots and directional trends were mapped using Getis-Ord Gi* statistics and standard deviation ellipses, and district-level spatial associations were evaluated. Multiscale Geographically Weighted Regression (MGWR) was used to model the relationships between disease incidence and geographic features. Five major transmission phases were observed. Specifically, 20 Health Districts were affected between March and April 2020, 38 in September 2020, 62 in April 2021, and 67 in December 2021. Initially, a single hotspot centered in Ouagadougou was identified. A second hotspot emerged in Bobo Dioulasso in September 2020, considerable heterogeneity in case distribution was noted across the districts. The MGWR results highlight population density, poverty rate, relative wealth index, and distance to testing centers as the main spatial drivers, collectively explaining 70% of the variance in incidence. The findings revealed a fast-evolving outbreak with significant spatial variation, revealed the need for adaptive, geography-informed responses. This multiphase framework can inform real-time risk forecasting and improve epidemic preparednessin in low-resource settings.
