17 cases of dengue were reported from the town of El Playón (7°28'15"-N/73°12'00"-W/altitude 510 masl) during epidemiological study weeks 5-6 and 12-13/2010. The Santander Department's Health Secretariat sought outbreak investigation and community knowledge-attitudes-practice (KAP) assessment on 16-4-2010 concerning a dengue fever outbreak in the town after an epidemiological surveillance committee had met; this was to strengthen local action regarding Aedes aegypti vector promotion-prevention-control.
This was a descriptive outbreak investigation study using an active search for cases having clinical manifestations of dengue according to protocol definitions, an entomological survey and a KAP survey of 47 people selected by simple-random-sampling. Data was systematised and analysed using Epi-INFO (3.5.1) with measures of central tendency-male ratio, in-house Aegypti (IA), water-storage (WI) and Breatau (BI) indexes.
4,774 clinical records were examined. There were 67 records compatible with dengue, 24 cases were notified (75 % town-25 % department), 15 (63 %) being women and 9 (38 %) men. 20 (83 %) cases occurred in the urban area and 4 (17 %) in rural areas. Attack rate/cumulated incidence: initial=0.3 % (17/6 303), final=0.4 % (24/6 303), male ratio=1.5. 47 houses and 142 water-storage items proved positive: low water-stores=8.7 %(4/46), rubber tyres=8.3 %(1/12), others=4.4 %(2/45), plants=2.9 %(1/34). IA=5 %, WI=6%, BI=17%, taxonomy confirmed=15 %(7/47). 47 KAP, 36 (77 %) women, 11 (23 %) men; knowledge on disease, symptoms and signs 44 (94 %), eliminating larvae deposits 32(68 %), asked about dengue 3(6 %), informed about responsibilities related to control 25(53 %).
The local community knows about risk factors and is aware of its responsibility regarding vector control. Community participation should be promoted using the ecosystem as a strategy for mosquito and dengue transmission control.
在2010年第5 - 6周和第12 - 13周的流行病学研究期间，埃尔普拉永镇（北纬7°28'15''/西经73°12'00''/海拔510米）报告了17例登革热病例。桑坦德省卫生秘书处于2010年4月16日在流行病学监测委员会召开会议后，对该镇登革热疫情进行了爆发调查，并对社区的知识、态度和实践（KAP）进行了评估；目的是加强针对埃及伊蚊病媒的促进、预防和控制方面的地方行动。
这是一项描述性爆发调查研究，按照方案定义积极搜索有登革热临床表现的病例，进行了昆虫学调查，并对通过简单随机抽样选出的47人进行了KAP调查。使用Epi-INFO（3.5.1）对数据进行系统化和分析，采用集中趋势测量指标——男女比例、室内埃及伊蚊（IA）、储水（WI）和布雷图（BI）指数。
检查了4774份临床记录。有67份记录符合登革热，报告了24例（75%来自镇，25%来自省），其中15例（63%）为女性，9例（38%）为男性。20例（83%）发生在市区，4例（17%）发生在农村地区。发病率/累积发病率：初始为0.3%（17/6303），最终为0.4%（24/6303），男女比例为1.5。47所房屋和142个储水物品检测呈阳性：低水位储水容器为8.7%（4/46），橡胶轮胎为8.3%（1/12），其他为4.4%（2/45），植物为2.9%（1/34）。IA为5%，WI为6%，BI为17%，分类学确认率为15%（7/47）。47份KAP调查中，36例（77%）为女性，11例（23%）为男性；对疾病、症状和体征的知晓率为44（94%），消除幼虫滋生地的知晓率为32（68%），被问及登革热的为3（6%），知晓控制相关责任的为25（53%）。
当地社区了解危险因素，并意识到其在病媒控制方面的责任。应通过将生态系统作为蚊虫和登革热传播控制的策略来促进社区参与。
