WAcute lower respiratory infections, which broadly include pneumonia and bronchiolitis, are still the leading cause of childhood mortality. ALRI contributed to 18% of all deaths in children younger than five years of age in 2008, and the main pathogens responsible for high mortality were Streptococcus pneumoniae, Haemophilus influenzae and respiratory syncytial virus. In addition, meningitis was estimated to contribute up to
200 000 deaths each year, and influenza anywhere between
25 000 and 110 000. It is widely acknowledged that a major portion of this mortality should be avoidable if universal coverage of all known effective interventions could be achieved. However, some evaluations of the implementation of World Health Organization’s (WHO) Integrated Management of Childhood Illness (IMCI) strategy, which promotes improved access to a trained health provider who can administer “standard case management”, have shown somewhat disappointing results. Only a minority of all children with life-threatening episodes of pneumonia, meningitis and influenza in developing countries have access to trained health providers and receive appropriate
treatment. Thus, novel strategies for control of pneumonia
that balance investments in scaling up of existing interventions and the development of novel approaches, technologies and ideas are clearly needed
