Estimated number of individuals (in millions) that still need to be vaccinated against yellow fever in 2016 to achieve the population coverage threshold of 80% recommended by WHO to prevent outbreaks, in every district or municipality in each country of Africa and Latin America that is classified as either completely or partially at risk for yellow fever. Separate estimates are given on the basis of the three alternative targeting scenarios for historical campaigns. Countries are ordered from greatest number needed to vaccinate to smallest across at-risk districts, for each continent. Estimates for each district or municipality are available in Dryad.
Estimated number of individuals requiring vaccination based on districts within areas classified by WHO range map as endemic or transitional.26
Estimated number of individuals requiring vaccination based on all districts in countries partially or completely classified as endemic or transitional by the WHO range map in addition to districts classified as having low potential for exposure to yellow fever virus, defined as areas where yellow fever has not been reported (but evidence of viral transmission in the past might exist), areas bordering endemic zones, or areas where yellow fever vectors and non-human primate hosts are present.2
