Table 1: Data sources on EVD and non-EVD mortality in Liberia, Sierra Leone and Guinea.
Notes: * The population size for each country are obtained from projections conducted by the UN population division and available at: http://esa.un.org/unpd/wpp/Excel-Data/Interpolated.htm; the figures used in this paper correspond to the "medium fertility" scenario devised by the UN population division ** The IHME counts of deaths and life tables for LSLG are available at: http://ghdx.healthdata.org/record/global-burden-disease-study-2013-gbd-2013-age-sex-specific-all-cause-and-cause-specific; *** The WHO counts of deaths and life tables for LSLG are available at: http://www.who.int/healthinfo/global_burden_disease/estimates/en/index1.html †The Liberian ministry of health does not report deaths separately by case definition since November 2014; ‡These figures are drawn from tables S10-S12 (confirmed + probable) and tables S14-S16 (confirmed + probable + suspected) of reference [29]. They concern the period from December 2013 to November, 25th 2014.
