Impact of EVD deaths on age-specific death rates, by pre-outbreak life table and country.

Notes: The relative risk ratios are calculated by dividing age-specific death rates in the presence of EVD deaths by age-specific death rates prior to the EVD outbreak. The y-axis is plotted on a logarithmic scale. EVD specific death rates were calculated by dividing the number of EVD deaths in 2014 in scenario, by estimates of the mid-year population for each country in 2014 obtained from UN projections. We used the mid-year population as an approximation of the number of person-years lived in each country in 2014. Unlike Liberia and Sierra Leone, the low EVD scenario for Guinea has CFR = 0.66. This is the CFR obtained from situation reports (see table 1).
