Community-based treatment of severe childhood pneumonia
Robert E Black, Shams El Arifeen

In 2010, an estimated 7·6 million children died before their fifth birthday, and more than a million of these deaths were due to pneumonia.1 Although progress is being made in expanding the use of vaccines to prevent pneumonia, many countries have yet to introduce these vaccines, especially the pneumococcal vaccine.2 Correct breastfeeding of children can also help prevent pneumonia deaths, but a high prevalence of suboptimum breastfeeding practices (eg, low rates of exclusive breastfeeding up to 6 months of age) is seen in all regions of the world.
