Comparisons of the cumulative number of cases of cholera averted by oral cholera vaccine (OCV) and water, sanitation and hygiene (WASH) scenarios applied to Haitian urban (U) and rural (R) populations by using Malawi, Mozambique, and India 20-year endemic cholera incidence data as baseline^*

^*Combi = combination of WASH and OCV.

^†Total cumulative cholera incidence (with a discounting rate of 3% per year): Malawi baseline incidence rate scenario: 106,994 cases; Mozambique baseline incidence rate scenario: 142,754 cases; India baseline incidence rate scenario: 9,635 cases.
