Pneumonia is the single largest cause of mortality in children aged under five years, causing an estimated 15.5% of all deaths in children under five years of age, and over 800,000 paediatric deaths annually (Liu et al., 2016; UN IGME, 2018). Most of these lives could be saved through more effective and equitable health system interventions, combining prevention, early and accurate diagnosis, and treatment (Walker et al., 2013; Rambaud-Althaus et al., 2015). The main pneumonia burden remains disproportionately concentrated in low- and middle-income countries (LMICs) in Southeast Asia and sub-Saharan Africa (Walker et al., 2013).
