Dengue fever, widely distributed throughout the world, has reemerged in Argentina after more than 70 years of absence, with an endemic behaviour in the northern provinces of the country. During the year 2016 an epidemic spread to the Province of Buenos Aires was experienced.
To characterize the outbreak of dengue fever occurred in the Province of Buenos Aires, Argentina, during the period of beginning and expansion between January and May of the year 2016.
The National Health Surveillance system provided weekly data, also using ArcGis for spatial localization. Knox test was used to establish spatial-temporal coordinates and the epidemiological curve was designed calculating the diffusion coefficient.
The relative risk and rates confirmed the epidemiological outbreak characterized by a rapid increase in propagation, with defined conglomerates. Towards week 17 the outbreak falls having the lowest diffusion values.
The information evaluated through different systems of information and analysis allowed to identify weaknesses of the same ones as well as to visualize "hot spots" of circulation of the virus in order to determine actions aimed at concentrating the efforts of control of potential breeding grounds for immature mosquitoes in winter times.
登革热在全球广泛分布,在阿根廷消失70多年后再度出现,在该国北部省份呈地方病特征。2016年期间,一场疫情蔓延到了布宜诺斯艾利斯省。
描述2016年1月至5月发病初期及疫情蔓延期间在阿根廷布宜诺斯艾利斯省发生的登革热疫情。
国家卫生监测系统提供每周数据,同时使用ArcGis进行空间定位。采用诺克斯检验确定时空坐标,并通过计算扩散系数绘制流行病学曲线。
相对风险和发病率证实了此次流行病学疫情的特征是传播迅速增加,形成了特定的聚集区。到第17周时疫情平息,扩散值最低。
通过不同信息系统和分析评估的信息有助于识别这些系统的弱点,并直观呈现病毒传播的“热点”,从而确定旨在集中力量在冬季控制未成熟蚊子潜在滋生地的行动。
