The strength of the re-emergence of dengue virus and the severity of these infections put this disease in the priority agenda of the institutions responsible for protecting the health of populations. Important for understanding the epidemiology of dengue nowadays refers to the knowledge of the patterns of spatial-temporal diffusion, though there is few research addressing this issue. This study describes the process of dissemination of dengue in the state of Bahia, from 1994 to 2000.
This ecological study space-time, with the units of analysis, county, epidemiological week, month, trimester and year. There has been construction of the trend line and has been mapping the sequential occurrence of dengue in the municipality for the period.
There were 164,050 reported cases of dengue and the introduction of this virus in Bahia, unlike other states, occurred on a small city, though there is intermittency in spatial and temporal records of cases at the beginning of this epidemic. The virus circulated in all climatic zones fact what highlight its high transmission power. The highest intensity of detection of cases and territorial expansion was in the littoral (zone humid and half-humid) ideal area for the survive of the vector.
Hypothetically, the intermittent space-time pattern initially observed, could have allowed the control of the progression of the epidemic, if structured action to vectorial combat was carried out.
登革热病毒再次出现的强度以及这些感染的严重性，使该疾病成为负责保护民众健康的机构优先关注的议程。如今，对于理解登革热流行病学而言，重要的是掌握时空扩散模式的相关知识，不过针对这一问题的研究较少。本研究描述了1994年至2000年期间巴伊亚州登革热的传播过程。
这项生态时空研究，分析单位为县、流行病学周、月、季度和年份。构建了趋势线，并绘制了该时期内该市登革热的连续发病情况。
共报告了164,050例登革热病例，与其他州不同，该病毒在巴伊亚州是在一个小城市首次出现的，尽管在疫情初期病例的时空记录存在间歇性。该病毒在所有气候区都有传播，这凸显了其高传播力。病例检测强度最高以及地域扩张最大的是沿海地区（湿润和半湿润地带），这是媒介生存的理想区域。
假设当初对最初观察到的间歇性时空模式采取针对媒介的结构化防治行动，本可控制疫情的发展。
