Cholera was reported in Latin America in 1991 and the main media was polluted water. To find ways to disinfect water other than boiling, according to the report that sunlight can inactivate several pathogenic E. coli strains in oral rehydration, the authors tested Sunshine disinfection with 2L plastic bottles and 1L glass bottles filled with water, inoculated 2 × 10 ~ 5CFU / ml of O1 group Vibrio cholerae, half of the water and placed in the noon sun, half in the shade on the experimental Ecuador’s two places, one at an altitude of 2850m, the other 500m. Results at 2850m Department
