Abstract

The purpose of this study is to investigate the global epidemiological characteristics of lower respiratory infections (LRI) burden attributable to respiratory syncytial virus (RSV) from 1990 to 2019. We used the recent Global Burden of Disease Study (GBD) 2019 to systematically evaluate the current burden and temporal trend of LRI burden attributable to RSV by global, age, sex, geographic location, and socio-economic status. Globally, the disability-adjusted life years (DALYs) cases of LRI attributable to RSV dropped from anestimated 39,964,488 [95% uncertainty interval (UI): 16,825, 572 to 68,800,553] in 1990 to 14,956,514 (95%UI: 6,271,751 to 25,910,753) in 2019 and estimated death cases droped from 541,172 (95%UI:226,614 to 958,596) to 338,495 (95%UI:126,555 to 667,109) from1990 to 2019. Similarly, age-standardized DALYs rate of LRI attributable to RSV decreased from an estimated 646.2 (95%UI: 276.9 to 1121.5) in 1990 to 218.3 (95%UI:92.1 to 376.8) in 2019 and estimated age-standardized deaths rate decreased from 10.3 (95%UI:4.1 to 18.5) to 4.8 (95%UI:1.8 to 9.3) between 1990 and 2019. In 2019, the highest age-standardized DALYs and death rates of LRI attributable to RSV were seen in the lower SDI regions, children and old people. From 1990 to 2019, age-standardized DALYs and death rates of LRI attributable to RSV decreased with increasing SDI. In this study, we found that the LRI burden attributable to RSV decreased significantly from 1990 to 2019. However, the lower SDI regions, children and old people urgently require cost-effective interventions to prevent and reduce the LRI burden attributable to RSV.
