    245 maternal-child dyads were followed from birth to 24 months, with RSV infections detected using RT-qPCR and serological tests.

  • 3

    RSV cumulative incidence increased significantly from 49% with RT-qPCR alone to 75% when combining RT-qPCR and serology (P < .001).

  • 4

    Classification and regression trees identified specific IgG and IgA thresholds indicative of RSV infections, improving detection sensitivity.

  • 5

    The study highlights the importance of combining methods to reduce selection bias and improve the understanding of RSV infection dynamics.
