Earlier and prolonged respiratory syncytial virus (RSV) seasons in young children compared to adults: implications for prevention in infants.
Article in Microbiology spectrum, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Respiratory syncytial virus (RSV) poses a major health concern, particularly for young children and older adults. In this 10-year, single-center retrospective study (15 May 2015 to 14 May 2025), we analyzed RSV positivity rates to characterize local epidemiologic trends. When stratified by age, children ≤2 years consistently exhibited the highest positivity rates. Using the Centers for Disease Control and Prevention's 3% positivity threshold, we found that the RSV season in the general population in our region began in early July and ended in late December, approximately 3 months earlier than the national average. Among infants ≤2 years, the season lasted 5 weeks longer on average than in the general population. These findings highlight regional variability in RSV seasonality and the earlier onset and extended duration of RSV activity in young children. This age group appeared particularly susceptible and likely played a key role in initiating and sustaining community transmission. Monitoring RSV positivity specifically in children ≤2 years, separate from the general population, may enhance local surveillance accuracy and support more timely decisions regarding RSV immunoprophylaxis and vaccination strategies. IMPORTANCE: Respiratory syncytial virus (RSV) is a major health concern, especially for young children and older adults. In this study, we explored whether different age groups changed the timing of RSV season. This is important because public health guidelines, hospital preparedness, and preventive strategies like antibody prophylaxis and vaccination rely on accurate RSV season timing. By showing how RSV trends differ by age, our findings can help improve seasonality responses and ensure that preventive measures reach high-risk groups, especially infants, at the right time.
