Pediatric respiratory syncytial virus infections associated with hospital airborne viral genetic load detection.
Article in Infection control and hospital epidemiology, 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
objectivesThis study investigates the potential aerosol transmission of respiratory syncytial virus (RSV), a major cause of viral pneumonia and bronchiolitis in young children.
methodsTwo hundred samples were collected in a long-term environmental surveillance program from January 2022 until January 2023. Samples were collected in a pediatric emergency corridor. The analyses were performed using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) targeting the RSV matrix gene. Information on the daily number of emergencies related with pediatric RSV infections was provided by the hospital.
resultsAerosol samples collected from a pediatric hospital corridor revealed detectable RSV RNA, particularly during peak infection seasons. RSV RNA was detected in 35 of 200 aerosol samples with a median concentration (interquartile range) of 1.8 (4.1) gc/m
conclusionsRSV RNA has been detected in aerosols in a healthcare setting, particularly during peak infection periods. This does not constitute evidence of transmission of the RSV via aerosols. However, the observed correlation with pediatric RSV cases suggests that further research on viral viability and infectivity from RSV detected in aerosols should be conducted. It also shows the potential of characterizing RSV RNA in aerosols for environmental surveillance purposes.
