Dengue is considered to be the most important arbovirus worldwide, with important complications that increase its lethality. In Brazil, an endemic country, the disease reaches significant incidence levels, with occurrences of serious cases and high costs of hospitalizations for its treatment.
To analyze risk factors among individuals with recent histories of dengue infection in a medium-sized city in Mato Grosso.
Descriptive cross-sectional study, of epidemiological-survey type, conducted among the urban population of a city located in mid-northern Mato Grosso.
A seroepidemiological survey using questionnaires and collection of biological material was conducted among 596 adults aged ≥ 18 years who had been selected through a cluster sampling process. Positive dengue cases were those with positive results from anti-dengue immunoassays (ELISA). Statistical analyses with descriptive and inferential techniques were used, with 95% confidence intervals and a 5% significance level.
The seroepidemiological profile of the study participants was predominantly female, with ages between 18 and 39 years, self-declared non-white race/color, not more than eight years of education and not living with a companion. Among the sanitary factors analyzed, the following were risk factors for dengue virus infection: no running water at home; no water supply from the public piped network; no waste from drains or toilets sent to the sewage network; endemic disease combat agents visiting the home; and presence of mosquito breeding sites at home.
Low schooling levels and previous dengue virus infection were associated with current dengue virus infection.
登革热被认为是全球最重要的虫媒病毒之一，其严重并发症使其致死率增加。在巴西这个流行地区，该病的发病率很高，会出现严重病例，治疗费用也很高。
分析马托格罗索州中北部一个中型城市近期登革热感染个体的危险因素。
描述性横断面研究，采用流行病学调查类型，对位于马托格罗索州中北部的一个城市的城市人口进行研究。
通过聚类抽样过程选择了 596 名年龄≥18 岁的成年人进行血清流行病学调查，使用问卷调查和采集生物材料。登革热阳性病例是指抗登革病毒免疫测定（ELISA）阳性的病例。采用描述性和推断性统计技术进行统计分析，置信区间为 95%，显著性水平为 5%。
研究参与者的血清流行病学特征主要为女性，年龄在 18 至 39 岁之间，自认为是非白色人种/肤色，受教育程度不超过 8 年，没有伴侣。在所分析的卫生因素中，以下因素是登革病毒感染的危险因素：家中无自来水；无公共管道网络供水；污水或厕所废物未送入污水管网；地方病防治人员访问家庭；家庭中存在蚊子滋生地。
低教育水平和既往登革热病毒感染与当前登革热病毒感染有关。
