Design outcomes

Primary

Measure	Time frame
To estimate the incidence of RSV LRTI in infants according to month of age.	—

Secondary

Measure	Time frame
To describe clinical epidemiology and economic burden of LRTI and RSV LRTI including severity, complications, hospitalization rate, disease course, patient pathway, factors contributing to severity and medical resource consumption according to month of age and week. To describe molecular epidemiology of RSV LRTI and LRTI attributable to other pathogens to understand whole picture of causative pathogens of infant LRTI using FilmArray panel and NGS.	—
