Arboviral diseases are disseminated all over the world. In Brazil, they remain neglected, alerting public authorities to possible outbreaks. Over here, we report the epidemiological indicators of Dengue from 2010 to 2015, Zika between 2015 and 2016, and Chikungunya from 2014 to 2016, within 19 municipalities of Southwestern Region of Bahia, Brazil. The data were collected from Brazilian national public information systems (SISFAD, SINAN, and IBGE) and by Endemic Control Agents. The analysis consisted of a description of vector characteristics, Home Infestation Index and characterization of human reported cases. The years 2011 and 2013 were recorded as having the highest frequencies of positive properties for the presence of the arboviruse vectors. Most municipalities presented high annual values of Home Infestation Index indicating an alert situation (62.28%). In the evaluated period, there were (i) 9,196 cases of Dengue, (ii) 636 cases of Zika and (iii) 224 cases of Chikungunya reported. This is the first report of the epidemiological characteristics of these arboviruses in the 19 municipalities of Bahia. It is believed that the data collected may contribute to public health policies aimed at controlling future epidemics of these arboviruses.
虫媒病毒病在全球范围内传播。在巴西，这些疾病仍未得到重视，这提醒了公共当局注意可能发生的疫情爆发。在此，我们报告了巴西巴伊亚州西南部 19 个城市 2010 年至 2015 年登革热、2015 年至 2016 年寨卡病毒以及 2014 年至 2016 年基孔肯雅热的流行病学指标。这些数据是从巴西国家公共信息系统（SISFAD、SINAN 和 IBGE）和地方传染病控制机构收集的。分析包括了蚊虫特征、家庭感染指数和报告的人类病例特征的描述。2011 年和 2013 年被记录为虫媒病毒病存在的阳性特征频率最高的年份。大多数城市的家庭感染指数年值都很高，表明存在警报情况（62.28%）。在所评估的时期内，有（i）9196 例登革热病例，（ii）636 例寨卡病毒病例和（iii）224 例基孔肯雅热病例报告。这是首次报告这些虫媒病毒在巴伊亚州 19 个城市的流行病学特征。据信，所收集的数据可能有助于制定旨在控制未来这些虫媒病毒病疫情的公共卫生政策。
