Assessment of the healthcare burden of dengue disease in England: a retrospective analysis (2010-2023).
Article in Journal of travel medicine, 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
backgroundDengue virus is transmitted by Aedes mosquitos, which are now prevalent in destinations commonly visited by UK travellers. Increased international travel and factors including climate change contribute to the global increase in dengue cases. Here, we evaluate the healthcare burden of dengue in England.
methodsThis retrospective, descriptive, cohort study (2010-2023) utilized data collected from National Health Service healthcare records in the Clinical Practice Research Datalink Aurum, linked with Hospital Episode Statistics, and Office for National Statistics mortality data. The primary objective was to determine the occurrence of hospitalized dengue. Other objectives were evaluation of healthcare resource utilization and costs, characteristics of hospitalized dengue cases, and complications due to dengue. Exploratory cohorts for suspected dengue in primary care were also reported.
resultsData from Clinical Practice Research Datalink-linked records for 596 patients comprising the hospitalized dengue cohort were evaluated; the incidence rate of hospitalized dengue progressively increased from 2010 until the highest in 2019 (5.8 per million person-years); rates increased in 2022 after COVID-19 lockdowns. Approximately one-third of hospitalized dengue cases were aged 18-29 years, most were White or Asian, and the most common complication was gastrointestinal conditions (gastroenteritis/colitis; 34.7 cases per 1000 person-years). Healthcare costs in the year following hospitalized dengue cases were mostly driven by inpatient admission costs; ~20% of cases had a subsequent hospital admission (~50% were dengue-related). A total of 2286 suspected cases of dengue were reported in primary care, with 1066 unconfirmed and 1220 confirmed cases.
conclusionsIncreasing incidence of dengue cases in England has followed global trends. The associated healthcare burden of imported dengue suggests a need for targeted public health strategies, particularly among younger travellers. Improvements in general practitioners' reporting of suspected dengue cases and associated details of symptoms and travel history are warranted.
