Background: In African rural settings, medically certified information on causes of death is largely lacking. The authors applied the verbal autopsy to identify causes of death before 15 years old in a rural area of Senegal where a demographic surveillance system is operating.
Methods: Between 1989 and 2000, a postmortem interview was conducted using a standardized questionnaire which was independently reviewed by two physicians who assigned the probable underlying cause of death. Discordant diagnoses were discussed by a panel of physicians. Causes of death were grouped into a few categories; cause-specific mortality rates and fractions were generated.
Results: Between 1989 and 1997, all-cause mortality fluctuated. Diarrhoeal diseases, malaria and acute respiratory infections explained between 30% and 70% of the mortality before 10 years of age. In children 1-9 years old, malaria death rate increased between 1989 and 1994 and thereafter did not change. The 1998-2000 years were marked by a peak in mortality, attributed to a meningitis outbreak in children more than one year old paralleled by an increase in death rate from fever of unknown origin, diarrhoeal diseases, and acute respiratory infections in children under 5 years.
Conclusions: Verbal autopsy provided useful information on the mortality structure responsible for the 1998-2000 peak in mortality. It underlined that, outside outbreak situations, malaria was a leading cause of death for 1-9 year old children and that diarrhoea, acute respiratory infections, or fever from unknown origin accounted for up to 50% of the deaths among the children under 5 years.
