Child survival revolutions revisited – lessons learned from Bangladesh, Nicaragua, Rwanda and Vietnam

Analysing child mortality may enhance our perspective on global achievements in child survival. We used data from surveillance sites in Bangladesh, Nicaragua and Vietnam and Demographic Health Surveys in Rwanda to explore the development of neonatal and under-five mortality. The mortality curves showed dramatic reductions over time, but child mortality in the four countries peaked during wars and catastrophes and was rapidly reduced by targeted interventions, multisectorial development efforts and community engagement. CONCLUSION Lessons learned from these countries may be useful when tackling future challenges, including persistent neonatal deaths, survival inequalities and the consequences of climate change and migration.
