ArboAlvo: stratification method for territorial receptivity to urban arboviruses.

Objective: To present the urban arboviruses (dengue, zika and chikungunya) stratification methodology by the territorial receptivity Index, an instrument for the surveillance and control of these diseases, which considers the heterogeneity of an intra-municipal territory.

Methods: Ecological study that uses as unit of analysis the areas covered by health centers in Belo Horizonte. For the development of a territorial receptivity index, indicators of socio-environmental determination of urban arboviruses were selected in order to integrate the analysis of main components.

[ARBOALVO: territorial stratification for definition of areas for prompt response by surveillance and timely control of urban arbovirus infections].

The study aimed to present the methodological proposal entitled "Prompt Response", modelled in the cities of Belo Horizonte (Minas Gerais State) and Natal (Rio Grande do Norte State), Brazil. The proposal aims to identify and demarcate priority areas for timely targeting of surveillance activities, aiming to reduce the intensity and velocity in the spread of epidemics in endemic urban areas. The methodology uses three variables that represent the necessary causes for the production and reproduction of dengue: notified cases (virus), Aedes eggs (vector), and population (host).

Vulnerability to severe forms of COVID-19: an intra-municipal analysis in the city of Rio de Janeiro, Brazil.

Given the characteristics of the COVID-19 pandemic and the limited tools for orienting interventions in surveillance, control, and clinical care, the current article aims to identify areas with greater vulnerability to severe cases of the disease in Rio de Janeiro, Brazil, a city characterized by huge social and spatial heterogeneity. In order to identify these areas, the authors prepared an index of vulnerability to severe cases of COVID-19 based on the construction, weighting, and integration of three levels of information: mean number of residents per household and density of persons 60 years or older (both per census tract) and neighborhood tuberculosis incidence rate in the year 2018. The data on residents per household and density of persons 60 years or older were obtained from the 2010 Population Census, and data on tuberculosis incidence were taken from the Brazilian Information System for Notificable Diseases (SINAN).

[Indicator of socio-environmental vulnerability in the Western Amazon. The case of the city of Porto Velho, State of Rondônia, Brazil].

The accelerated process of urbanization in the State of Amazônia associated with changes in the patterns of exploitation of natural resources have resulted in several types of environmental impacts, such as urban air pollution produced by forest fires which alters the relationship between urban and rural areas and establishes new vulnerabilities. The scope of this study is to analyze the socio-environmental vulnerability in relation to forest fires and health effects in the urban area of Porto Velho, located in the Brazilian Amazon region. Data was analyzed using a synthetic indicator combining income and education aspects, housing infrastructure, environmental exposure and health effects.

[Use of local level indicators for the spatial analysis of morbidity due to diarrhea and its relation with lifestyle conditions].

Every child had an average of three episodes of diarrhea per year in developing countries in the twentieth century. The decrease of the number of deaths due to diarrhea in Brazil was more closely related to the use of control techniques than to changes in lifestyle conditions. This article seeks to analyze the spatial distribution of morbidity due to diarrhea among children and its relation with lifestyle conditions.
