Overview

Retrospective study analyzes RSV infection patterns in children under five, suggesting new prevention strategies.

Key Points

  • To characterize epidemiological trends, seasonal patterns, and risk factors for RSV infection in children under five years.
  • Retrospective analysis using sentinel hospital surveillance data from January 2018 to December 2023.
  • Children aged under five presenting with acute respiratory symptoms were tested for RSV via RT-PCR.
  • Multivariable logistic regression was used to identify factors associated with RSV positivity.
  • Among 42,856 children tested, 7634 (17.8%) were RSV-positive, highest in those aged 6–11 months (24.3%).
  • Higher positivity in males (19.2%) compared to females (16.1%, P < 0.001).
  • RSV infection severity increased post-pandemic, with ICU admissions rising from 4.2% to 6.8% in 2022–2023.
