Relative risk (A) and expression (B) of RSV N gene detected in cord blood samples collected in winter and non-winter months. RSV N gene expression was more likely to be detected in samples collected during winter birth months (17/21, 81%; 95% CI 64.2–97.7) compared to cord blood samples from non-winter birth months (9/24, 37.5%; 95% CI 18.1–56.9, Fishers exact analysis). Of those samples where RSV was detected, no significant difference in RSV N gene expression was observed between winter and non-winter birth months (Mann-Whitney U analysis, p = 0.567).
