Across children and adolescents aged 0–19 years, the integrated spectrum of 29 respiratory infectious causes became more diverse from 1990 to 2023, with Shannon diversity rising from 2.336 to 2.711 (+16.1%).
- Why it matters: Cause modules have been reported separately, leaving uncertainty about how the combined mortality mix has shifted over time and what that means for designing interventions.
- What they did: The study integrated Global Burden of Disease Study 2023 (release v8352) estimates for 1990–2023 into a 29-cause spectrum across seven super-regions, using Shannon diversity, Herfindahl concentration, effective cause counts, joinpoint models, and vaccine-linked pathogen shares.
- The result: In 2023, 29 causes accounted for 965,330 deaths (95% UI 680,096–1,342,437), with effective cause counts nearly doubling (5.57 to 9.94) and diversification accelerating after 2013–2020 (+1.18% per year).
