Abstract

Ovitraps can detect Aedes vectors at an early stage and can serve as an alarm indicator for outbreak prediction. This study aimed to summarize the available literature about the ovitrap system and to determine its feasibility, required resources and costs when installing and maintaining this vector surveillance system in the municipality of Los Patios, Colombia. A scoping review to assess the role of ovitraps as a tool for Aedes vector surveillance was conducted. The subsequent fieldwork consisted of mapping the municipality, manufacturing, and installing 40 ovitraps in 10 blocks, revising them weekly for 4 weeks by two half-time employed vector control technicians, and carrying out a cost analysis. A total of 38 studies were included in this review showing that ovitraps had a better performance than other entomological surveillance methods and a positive correlation with other entomological and disease variables. From the field results over 4 weeks, a high proportion of positive ovitraps (80%, 90%, 75%, 97.5%) and positive blocks (100%) as well as a good acceptance by house owners (76.9%), were identified. Operational indicators such as average installation time of the ovitraps (10h15 m), weekly reading and reinstallation (on average 7h27 m) and the cost of the intervention (COL$1,142,304.47/US$297) were calculated. Literature shows that ovitraps are sensitive to detect the presence of Aedes mosquitoes, providing data efficiently and timely for outbreak prediction. The field testing showed it is an affordable and feasible method in the context of a Colombian municipality and similar endemic areas.

墨西哥诱蚊诱卵器系统在哥伦比亚监测伊蚊病媒的适用性。
诱蚊器可在早期阶段发现伊蚊病媒,并可作为疫情预测的警报指标。本研究旨在总结有关诱蚊产卵器系统的现有文献,并确定在哥伦比亚洛斯帕提奥斯市安装和维护该病媒监测系统的可行性、所需资源和成本。进行了范围审查,以评估诱卵器作为伊蚊媒介监测工具的作用。随后的实地工作包括绘制城市地图,在10个街区制造和安装40个诱蚊产卵器,每周由两名兼职病媒控制技术人员进行4周的修改,并进行成本分析。本综述共纳入38项研究,结果表明诱卵器的监测效果优于其他昆虫学监测方法,且与其他昆虫学和疾病变量呈正相关。从4周的现场结果来看,诱卵器阳性率高(80%、90%、75%、97.5%),阳性阻滞率高(100%),业主接受度高(76.9%)。计算了诱卵器的平均安装时间(10h15 m)、每周读数和重新安装(平均7h27 m)以及干预成本(COL$1,142,304.47/US$297)等操作指标。文献显示,诱卵器对伊蚊的存在检测灵敏,为疫情预测提供了高效、及时的数据。现场试验表明,在哥伦比亚一个城市和类似的流行地区,这是一种负担得起且可行的方法。

期刊介绍: Pathogens and Global Health is a journal of infectious disease and public health that focuses on the translation of molecular, immunological, genomics and epidemiological knowledge into control measures for global health threat. The journal publishes original innovative research papers, reviews articles and interviews policy makers and opinion leaders on health subjects of international relevance. It provides a forum for scientific, ethical and political discussion of new innovative solutions for controlling and eradicating infectious diseases, with particular emphasis on those diseases affecting the poorest regions of the world.
