[The cholera epidemic in Latin America: reemergence, morbidity, and mortality].

OBJECTIVE
To determine morbidity and mortality from cholera during different segments of the period 1991-2011 in the countries of Latin America.


METHODS
Using information sources from a nonsystematic literature search for works on cholera epidemics, a mixed ecological study was conducted aimed at a time series analysis of morbidity, mortality, and case-fatality in cholera-related health events between 1991 and 2011 in 18 Latin American countries.


RESULTS
During the period 1991-2011, 1 839 037 cases of cholera were reported in Latin America, with 19 538 deaths and a case fatality rate of 1.06%. The most affected countries were Peru between 1991 and 2002-with a maximum annual cumulative incidence of 1 452.72 cases per 100 000 population but a low case fatality rate (0.72%)-and Haiti between 2010 and 2011, with a maximum annual cumulative incidence of 3 319.13 per 100 000 population and a case fatality rate of 1.32%.


CONCLUSIONS
The cholera epidemic has resulted in high morbidity, mortality, and case fatality in some Latin American countries, due largely to basically socioeconomic and climatic factors. The reemergence of this disease and the many factors related to how cholera outbreaks evolve call for the development and strengthening of regional prevention and control strategies in the countries as well as a study on the determinants that influence the emergence and reemergence of infectious diseases in Latin America.
