This study aimed to determine whether variations in the incidence of reported cases of human brucellosis in Ecuador were clustered in space and time. In addition, the effects of cattle and small ruminant population density and other socio-economic factors on the incidence were investigated. Significant space-time clusters were found in the northern and southern highlands and parts of Ecuadorian Amazonia. Customs of people, cattle, goat and sheep population density appeared to influence the incidence of brucellosis. In this study, the incidence of reported cases of human brucellosis was found to be higher in the highlands (sierra) and in municipalities near Peru and Colombia. The results of this study highlight the need for prevention and control measures aimed at abating the incidence of brucellosis among livestock and humans.
本研究旨在确定厄瓜多尔报告的人类布鲁氏菌病病例发生率的变化是否在空间和时间上呈聚集性。此外，还调查了牛和小反刍动物种群密度及其他社会经济因素对发病率的影响。在厄瓜多尔北部和南部高地以及部分亚马逊地区发现了显著的时空聚集性。人的习俗、牛、山羊和绵羊的种群密度似乎影响布鲁氏菌病的发病率。在本研究中，发现人类布鲁氏菌病报告病例的发病率在高地（山区）以及靠近秘鲁和哥伦比亚的市镇较高。本研究结果凸显了采取预防和控制措施以降低牲畜和人类中布鲁氏菌病发病率的必要性。
