Resurgence of malaria in northern Ethiopia (Tigray), 2018-2024: evidence from routine surveillance data.
Article in Tropical medicine and health, 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
Recent reports have documented a resurgence of malaria in several regions of Ethiopia; however, contemporary surveillance data from the Tigray region remain limited. This study analyzed malaria incidence trends in Tigray between 2018 and 2024 using routine surveillance data.Weekly malaria surveillance data were analyzed using descriptive and non-parametric statistical methods. Malaria incidence varied significantly across the study period. Compared with the 2018-2022 baseline period, median weekly incidence increased 2.5-fold in 2023. Elevated transmission persisted in 2024, with incidence remaining significantly higher than baseline levels through epidemiological week 27. The highest weekly incidence recorded in 2023 was approximately 4.8-fold greater than the baseline median. Spatial analyses revealed substantial heterogeneity, with a disproportionate burden concentrated in a limited number of woredas.Malaria incidence in Tigray increased significantly during 2023 and remained elevated in 2024. These findings address an important geographic gap in recent assessments of malaria epidemiology in Ethiopia and provide additional evidence that the malaria resurgence reported elsewhere in the country is also reflected in northern Ethiopia. Continued epidemiological and entomological surveillance, including monitoring for invasive vector species such as Anopheles stephensi, will be important for informing targeted malaria control efforts.
