A retrospective analysis was conducted of human cases and outbreaks of tularemia in the Republic of Armenia from 1996 to 2012 utilizing geographic information system software. A total of 266 human cases of tularemia were recorded in Armenia from 1996 to 2012, with yearly incidence ranging from 0 to 5.5 cases per 100,000 people. Cases predominantly affected the male population (62.8%), 11-20 year age group (37.2%), agricultural workers (49.6%), and persons residing in rural areas (93.6%). In 2003, a waterborne outbreak involving 158 cases occurred in Kotayk Marz, and in 2007, a foodborne outbreak with 17 cases occurred in Gegharkunik Marz, attributed to exposure of food products to contaminated hay. Geospatial analysis of all cases showed that the majority were associated with the steppe vegetation zone, elevations between 1,400 and 2,300 m, and the climate zone associated with dry, warm summers, and cold winters. Characterization of these environmental factors were used to develop a predictive risk model to improve surveillance and outbreak response for tularemia in Armenia.
利用地理信息系统软件,对1996年至2012年亚美尼亚共和国土拉菌病的人类病例和疫情进行了回顾性分析。1996年至2012年,亚美尼亚共记录了266例土拉菌病人类病例,年发病率为每10万人0至5.5例。病例主要影响男性人群(62.8%)、11至20岁年龄组(37.2%)、农业工人(49.6%)以及农村地区居民(93.6%)。2003年,科泰克省发生了一起涉及158例病例的水源性疫情,2007年,格加尔库尼克省发生了一起17例病例的食源性疫情,原因是食品接触了受污染的干草。对所有病例的地理空间分析表明,大多数病例与草原植被区、海拔1400至2300米以及夏季干燥温暖、冬季寒冷的气候区有关。利用这些环境因素的特征建立了一个预测风险模型,以改善亚美尼亚土拉菌病的监测和疫情应对。
