Solid waste management is a challenge in developing countries. The Structural dump in Brasilia, Brazil, was the largest Latin American open-air dump until its closure in 2018. Thus, this study sought to investigate the prevalence of self-reported dengue, Zika and Chikungunya arbovirus infections in waste pickers who worked at the dumpsite and assess its association with the sanitary conditions in their residences and workplaces. This research used a mixed methods study using a questionnaire for the quantitative method and semi-structured interviews for the qualitative portion. A cross-sectional, observational, epidemiological study along with a phenomenological study were carried out to characterize socio environmental, occupational and health-related aspects to vector-borne diseases in Structural dumpsite in Brazil. Of the 1,025 respondents, 301 (29.2%) reported to have gotten sick from dengue, Zika or chikungunya fevers. We found significant associations between place of residence of waste pickers (p = 0,003) and the work conditions, use of personal protective equipment (p < 0.001) and weekly workload (p = 0.04) and occurrence of vector-borne disease. Results were confirmed by qualitative data and geo-referencing, in relation to location of their homes and proximity to the dumpsite, as well as through the vulnerability due to their working conditions. This research confirms that waste pickers are highly susceptible to vector-borne diseases; this situation that needs to be immediately addressed by interdisciplinary and intersectoral approaches in waste management and public health. This information confirms vulnerability of waste pickers to diseases transmitted by Ae. aegypti mosquito as a result of sanitary conditions at their residence and workplace.
固体废物管理是发展中国家面临的一项挑战。巴西巴西利亚的结构性垃圾场是拉丁美洲最大的露天垃圾场，直到 2018 年关闭。因此，本研究旨在调查在垃圾场工作的拾荒者中自我报告的登革热、寨卡和基孔肯雅热虫媒病毒感染的流行情况，并评估其与居住和工作场所卫生条件的关系。本研究采用混合方法研究，使用问卷进行定量方法，使用半结构化访谈进行定性部分。进行了一项横断面、观察性、流行病学研究和现象学研究，以描述巴西结构性垃圾场的社会环境、职业和与虫媒疾病相关的方面。在 1025 名受访者中，有 301 名（29.2%）报告因登革热、寨卡或基孔肯雅热而生病。我们发现拾荒者居住地（p=0.003）与工作条件、个人防护设备使用（p<0.001）和每周工作量（p=0.04）之间存在显著关联，与虫媒疾病的发生有关。定性数据和地理参考证实了这一结果，涉及到他们的家和垃圾场的位置的接近程度，以及由于工作条件而导致的脆弱性。这项研究证实，拾荒者极易感染虫媒疾病；这种情况需要通过废物管理和公共卫生领域的跨学科和跨部门方法立即解决。这些信息证实了拾荒者由于居住和工作场所的卫生条件而容易感染埃及伊蚊传播的疾病的脆弱性。
