Malaria is still the major parasitic disease in the world, with approximately 438,000 deaths in 2015. Environmental risk factors (ERF) have been widely studied, however, there are discrepancies in the results about their influence on malaria transmission. Recently, papers have been published about geospatial analysis of ERF of malaria to explain wh...

Background Built environments have been shown to shape active living behaviours, including walking. However, this literature is drawn predominantly from Europe and North America. This study aimed to create a geospatially derived city-wide walkability index and further investigate the association with walking in Belo Horizonte, Brazil. Methodology...

Understanding how urban environments shape physical activity is critical in rapidly urbanizing countries such as South Africa. We assessed the reliability of virtual audits for characterizing urban features related to physical activity in Soweto, South Africa. We used the Microscale Audit of Pedestrian Streetscapes Global tool to characterize pedes...

In the rapidly evolving landscape of global health research, the tension between scientific rigor and contextual meaning presents a critical challenge. Drawing on our work with the Global Diet and Physical Activity Network, this commentary explores the complexities of conducting environmental audits for physical activity and diet in 4 rapidly urban...

Arboviral diseases such as dengue, Zika and chikungunya transmitted by Aedes mosquitoes have been reported in 34 African countries. Available data indicate that in recent years there have been dengue and chikungunya outbreaks in the West Africa subregion, in countries including Côte d’Ivoire, Burkina Faso, Gabon, Senegal, and Benin. These viral dis...

Aedes-transmitted arboviruses have spread globally due to the spread of Aedes aegypti and Aedes albopictus. Its distribution is associated with human and physical geography. However, these factors have not been quantified in Cameroon. Therefore, the aim was to develop an Ae. albopictus geo-referenced database to examine the risk factors associated...

New malaria control tools and tailoring interventions to local contexts are needed to reduce the malaria burden and meet global goals. The housing modification, screening plus a targeted house-based insecticide delivery system called the In2Care® Eave Tubes, has been shown to reduce clinical malaria in a large cluster randomised controlled trial. H...

We recently developed a superhydrophobic cone-based method for the collection of mosquito excreta/feces (E/F) for the molecular xenomonitoring of vector-borne parasites showing higher throughput compared to the traditional approach. To test its field applicability, we used this platform to detect the presence of filarial and malaria parasites in tw...

Background: The healthcare system can be understood as the dynamic result of the interaction of hospitals, patients, providers, and government configuring a complex network of reciprocal influences. In order to better understand such a complex system, the analysis must include characteristics that are feasible to be studied in order to redesign it...

Objective: To analyze the environmental and socioeconomic risk factors of malaria transmission at municipality level, from 2010 to 2015, in the Brazilian Amazon. Methods: The municipalities were stratified into high, moderate, and low transmission based on the annual parasite incidence. A multinomial logistic regression that compared low with me...

In response to innumerable global challenges in a world ever more complex and interconnected, including a number of public health challenges, the United Nations launched the 2030 Agenda for Sustainable Development; a guideline intended to deal with these issues. Foreseeing their huge complexity, the UNLEASH initiative was created with a vision to g...

Introduction: Malaria still is a public health problem in the Americas. In 2015, Brazil accounted for 37% of all cases in the Americas, and of these cases, 99.5% were located in the Brazilian Amazon. Despite the mobilization of resources from the Brazilian National Plan for Malaria Control, too many municipalities have high transmission levels. The...

The article aims to contribute to the discussion on the constitution of a field of knowledge of global health and sustainability in Latin America, from the analysis of the Graduate Program in Global Health and Sustainability of the Universidade de São Paulo, including its conceptual basis, research lines, supervisors, and student profiles. Data col...

This chapter defines some of the words in the title; geography, health and geo-technologies. Explaining the Geographic Information Systems (GIS), remote sensing, Global Position System (GPS) and spatial statistics. Lastly, the chapter focus on the point that the geo-technologies do not solve health problems by itself but with the interaction of the...

This chapter is about how the health system creates political boundaries of health as the countries organized their territories and citizens based in polygons drew in a map. It analyze the flows of the Brazilian health system (SUS) and it shows the use of the Geographic Information System (GIS) as a tool to the restructuring the health areas in the...

Introduction Malaria is still the major parasitic disease in the world, with approximately 600,000 deaths in 2013. Environmental risk factors of malaria have been widely studied, however, there are discrepancies on the results about their influence on malaria transmission. Recently, manuscripts have been published about spatial analysis of environm...

Os fatores de risco ecológicos da transmissão da malária estiveram por muito tempo focados exclusivamente na temperatura e na precipitação. No entanto, compreender a microclimatologia da área e do hábitat do vetor pode ajudar a predizer quando a transmissão da malária é mais provável que aconteça com o intuito de focalizar as atividades de controle...
