The role of birth month in the burden of hospitalisations for acute lower respiratory infections due to respiratory syncytial virus in young children in Croatia. Li, Y., Batinović, E., Milić, P., & Markić, J. PloS One, 17(9):e0273962, 2022. doi abstract bibtex BACKGROUND: Birth month was an important risk factor for respiratory syncytial virus (RSV) hospitalisation in infants. However, little is known about the role of birth month in RSV hospitalisation in finer age bands during infancy, which is relevant to strategies for RSV passive immunisations for infants. We aimed to understand the role of birth month in the burden of RSV-associated acute lower respiratory infection (ALRI) hospitalisation in finer age bands of the first year of life. METHODS: In this retrospective study, we analysed the hospitalisation records during 2014-19 at the University Hospital of Split, Split-Dalmatia County, Croatia. We estimated all-cause and RSV associated ALRI hospitalisation rates among children under five years, with a focus on infants by finer age band and birth month. RESULTS: We included 1897 ALRI hospitalisations during the study period. Overall in children under five years, annual hospitalisation rate was 14.66/1000 (95% CI: 14.01-15.34) for all-cause ALRI, and was 7.56/1000 (95% CI: 6.83-8.34) for RSV-ALRI. RSV-ALRI hospitalisation rate was highest in infants aged 28 days-\textless3 months (61.15/1000, 95% CI: 52.91-70.31). Infants born in November, December and January (2-3 months before RSV peak) had the highest hospitalisation rates during infancy. Depending on the birth month of infants, the risk of RSV-ALRI hospitalisation peaked at different months of age; infants who were born in September had the highest RSV-ALRI hospitalisation rate at the age of 3-\textless6 months. CONCLUSIONS: Our study underlines the importance of birth month in planning RSV immunisation strategies for infants, and provides useful baseline data for effectiveness analysis of novel RSV prophylactic products.
