Studies were eligible if they met the following inclusion criteria: (1) observational studies such as cohort and cross-sectional studies; (2) studies on humans; (3) studies on patients with RTI or influenza-like illness (ILI); (4) studies reporting incidence or proportion of RSV infection among respiratory related illness; and (5) studies on children aged 5 years or less.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Findings</h3>\u0000 \u0000 <p>A total of 4403 studies were identified from an initial search. After screening titles, abstracts, and full-text review, a total of 173 studies that met predefined eligibility criteria were included in the analysis. The overall proportion of RSV infections among all ARTIs was 18.7% (95% CI: 16.0%–21.5%), whereas the proportion of RSV infections among LRTIs was 28.7% (95% CI: 2.6%–30.3%) in children in Western Pacific and Southeast Asia Regions between 1970 and 2020. The proportion of RSV infections peaked in the 1980s at 33.4% (95% CI: 19.8%–48.5%), having increased from 10.6% (95% CI: 2.9%–22.2%) in the 1970s. It then showed a decreasing trend, with 28.9% (95% CI: 18.8%–40.3%) in the 1990s, 24.5% (95% CI: 22.3%–26.8%) in the 2000s, and 20.1% (95% CI: 17.8%–22.5%) in the 2010s. By country, Myanmar (50.0%; 95% CI, 47.5%–52.4%) and New Zealand (45.3%; 95% CI, 37.1%–53.7%) had the highest proportion during the overall time period, followed by Bhutan (45.2%; 95% CI, 36.4%–54.3%), Lao PDR (41.0%; 95% CI, 36.2%–46.0%), and Vietnam (35.5%; 95% CI, 19.3%–53.6%).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Interpretation</h3>\u0000 \u0000 <p>Substantial RSV-associated disease burden occurs in children in Western Pacific and Southeast Asia Regions.
