* u! s% U1 t$ |6 y9 WA US team, writing in the Lancet, looked at mortality figures from 2010.
1 b# v8 p# s7 @! _" [They found two-thirds of the 7.6m children who died before their fifth birthday did so due to infectious causes - and pneumonia was found to be the leading cause of death.

The team from Johns Hopkins Bloomberg School of Public Health looked at data from a range of sources, including household surveys and registration systems for 193 countries. Mathematical modelling was used where data was incomplete.  B4 k6 n+ T9 u% t
They found child deaths had fallen by two million (26%) since 2000, and there have been significant reductions in leading causes of death including diarrhoea and measles - as well as pneumonia.1 Y! [- M6 I9 p! m7 F
But they say there are still significant challenges.* z. Y7 `( w6 [; Q' P
International targets

Writing in the Lancet, the researchers say: "Across all the previous and current rounds of causes of childhood death estimation, pneumonia and pre-term birth complications consistently rank as the leading causes at the global level.
