Underlying causes of child death 
Currently, CHERG is working with WHO and UNICEF to develop methodologies and processes to estimate and publish annually the total burden of childhood mortality and causes of death, with first results available in 2009 for the year 2008 and published in 2010. These estimates will include, where the data permit, specific etiologies of diarrhea (e.g. rotavirus) and respiratory disease/meningitis (e.g.  pneumococcus or  H. influenzae type b.)

To date, CHERG has been able to produce one set of cause-specific mortality estimates for the year 2000 and the resulting distribution of causes has been replicated yearly, with very minor adjustments. This project will develop methods/models that allow for annual updates of under-five causes of death by incorporating information on effects of accelerated child survival interventions, such as accelerated coverage of vaccines, use of bednets, introduction of new vaccines (e.g. Hib, Rotavirus, etc), strengthening of community case management of pneumonia, expansion of newborn care interventions, etc.  A second step will involve the validation of the model outputs, requiring strong collaboration with specific programs implementing or scaling-up these interventions in one or two countries.   

Methods and Expected Products 
Epidemiologists, disease experts and statisticians/modelers make up several working groups that are systematically reviewing epidemiologic studies and other sources of data that have collected information on causes of under-five death. Working groups for diarrhea, pneumonia, malaria, and neonatal causes will identify, review, abstract, and analyze all relevant information, and make the information publicly available and disseminated through various channels. CHERG will work with WHO and UNICEF to publish national estimates of child causes of death for all countries beginning with 2008 and continuing annually.
