* The measles mortality model used to generate estimated measles cases and deaths is rerun each year using the new and revised annual WHO/UNICEF estimates of national immunization coverage (WUENIC) data, as well as updated surveillance data; therefore, the estimated number of cases and mortality estimates in this report might differ slightly from those in previous reports.

^† Estimated measles mortality was too low to allow reliable measurement of mortality reduction.
