Space and space-time distributions of dengue in a hyper-endemic urban space: the case of Girardot, Colombia.

Background: Dengue is a widely spread vector-borne disease. Dengue cases in the Americas have increased over the last few decades, affecting various urban spaces throughout these continents, including the tourism-oriented city of Girardot, Colombia. Interactions among mosquitoes, pathogens and humans have recently been examined using different temporal and spatial scales in attempts to determine the roles that social and ecological systems play in dengue transmission.

[Operation of government policies for the prevention and control of dengue: The cases of Arauca and Armenia].

Introduction: Dengue is a growing public health problem in urban areas, given that its transmission is associated with the environment, as well as with the behaviour of individuals and communities. The model proposed by Ecohealth to study this problem includes the operation of government policies.

Objective: To describe the operation of policies to prevent and control dengue in two Colombian cities.

Territorial analysis of Aedes aegypti distribution in two Colombian cities: a chorematic and ecosystem approach.

A territorial analysis of Aedes aegypti density was conducted in two Colombian cities using an ecosystem and chorematic approach. Entomological and behavioral data (by cluster) and information on the urban context were used to analyze the relationship between territorial structures and dynamics and vector density. The results were represented in graphic (chorematic) models.
