Outbreak of severe acute respiratory infections caused by recombinant human adenovirus type B 7/3 in hospitalized infants from a nursery in Dakar, April 2024.
Article in IJID regions, 2024. 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
Objectives: Acute respiratory infections are among the leading cause of mortality in children under 5 years of age worldwide, with most of these deaths due to bronchiolitis and pneumonia. We investigated and analyzed a pediatric outbreak of acute respiratory infections that resulted in the hospitalization of four infants in a nursery in Dakar in late April 2024. Methods: Nasopharyngeal specimens were collected from infants and tested for a panel of respiratory pathogens by multiplex real-time reverse transcription-polymerase chain reaction. Subsequently, the positive samples underwent next-generation sequencing for molecular analysis. Results: Human adenovirus (HAdV) was the principal etiologic agent detected in hospitalized infants with pneumonia and nearly half (46.7%; seven of 15) of the suspected cases identified during the investigation at the nursery. All the HAdV isolates were classified as being of subgroup B1. Molecular characterization revealed that infants attending the nursery were infected with a recombinant HAdV strain containing an adenovirus serotype 7 penton and serotype 3 hexon and fiber proteins. Conclusions: Our findings reinforce previous evidence that recombination leads to the emergence of new adenovirus strains with epidemic and lethal potential. These results emphasize the need to strengthen surveillance in inpatient settings across the country.
