GAVILAN, Ronnie G.  and  MARTINEZ-URTAZA, Jaime. Environmental drivers of emergence and spreading of Vibrio epidemics in South America. Rev. perú. med. exp. salud publica [online]. 2011, vol.28, n.1, pp.109-115. ISSN 1726-4634.

Vibrio cholerae and V. parahaemolyticus are the two Vibrio species with a major impact on human health. Diseases caused by both pathogens are acquiring increasing relevance due to their expansion at global scale. In this paper, we resume the ecological aspects associated with the arrival and spreading of infections caused by V. parahaemolyticus and V. cholerae in Peru from a South American perspective. Moreover, we discuss the similarities in the emergence in Peru of cholera cases in 1991 and V. parahaemolyticus infections in 1997. These constituted exceptional experiments to evaluate the relationships between the Vibrio epidemics and changes in the environment. The epidemic radiations of V. cholerae and V. parahaemolyticus constitute to clear examples supporting the oceanic dispersion of pathogenic vibrios and have enabled the identification of El Niño events as a potential mechanism for the spreading of diseases through the ocean.

Keywords : Vibrio Cholerae; Vibrio Parahaemolyticus; Epidemiology; El Niño Phenomenon; Vibrio infections.
