Recently, the role of the environment and climate in disease dynamics has become a subject of increasing interest to many scientists including microbiologists, clinicians, and epidemiologists. In this study, cholera outbreak during seven years (2000-2006) and climate factors were investigated. This study showed that there is a strong link between cholera outbreak and climate factors. When the temperature was <21.5C the outbreak started and when the temperature raised at 42C, the outbreak finished. However, the percentage of humidity had the same effect when it was 14% the outbreak begun and when it raised to 89% the outbreak finished too. In addition, the rate of rainfall also effected (i.e., when the minimum rainfall was 34.4 mm, the outbreak occurred and maximum rainfall raised to 567.9 mm the outbreak continued too.
