Cholera, a waterborne disease caused by Vibrio cholerae, is an autochthonous member of the aquatic environment and predominantly reported from developing countries. Technical reports and proceedings were reviewed to determine the relationship between occurrence of V. cholerae in natural waters, including sources of municipal water, and cases of cholera in Azerbaijan. Water samples collected from different environmental sources from 1970 to 1998 were tested for V. cholerae and 0.73% (864/117,893) were positive. The results showed that in April of each year, when the air temperature rose by approximately 5°C, V. cholerae could be isolated. With each increase in air temperature, 6-8 weeks after, impact on cases of cholera was recorded. The incidence of cholera peaked when the air temperature reached >25°C during the month of September. It is concluded that a distinct seasonality in cholera incidence exists in Azerbaijan, with increased occurrence during warmer months.
霍乱是一种由霍乱弧菌引起的水源性疾病，是水生环境中的固有成员，主要发生在发展中国家。审查了技术报告和议事录，以确定阿塞拜疆自然水域（包括城市供水源）中霍乱弧菌的出现与霍乱病例之间的关系。从 1970 年至 1998 年，从不同环境来源采集的水样进行了霍乱弧菌检测，阳性率为 0.73%（864/117893）。结果表明，每年 4 月，当空气温度升高约 5°C 时，可以分离到霍乱弧菌。此后，每升高 6-8 周，就会记录到对霍乱病例的影响。当 9 月的空气温度超过 25°C 时，霍乱的发病率达到峰值。结论是，阿塞拜疆的霍乱发病率存在明显的季节性，在温暖的月份发病率增加。
