ABSTRACT To correlate the incidence of leptospirosis with sociodemographic data in the Brazilian Unified Health System from 2011 to 2022. This ecological study used national health and economic secondary data sources. Secondary analyses summarized the scenario of disease-related hospitalizations among federative units. In total, two analyses were conducted: variable description for relationship analysis and a secondary analysis with population health and sanitation indicators and economic indicators from the Instituto Brasileiro de Geografia e Estatística (IBGE – Brazilian Institute of Geography […]

OBJECTIVE: To estimate the incidence rate of type 1 diabetes in the urban area of Santiago, Chile, from March 21, 1997 to March 20, 1998, and to assess the spatio-temporal clustering of cases during that period. METHODS: All sixty-one incident cases were located temporally (day of diagnosis) and spatially (place of residence) in the area of study. Knox’s method was used to assess spatio-temporal clustering of incident cases. RESULTS: The overall incidence rate of type 1 diabetes was 4.11 cases […]

OBJECTIVE: To describe the geographical distribution of tuberculosis incidence rates based on a set of epidemiological and operational indicators from information system database. METHODS: Data from the Sistema de Informação de Agravos de Notificação (Brazilian Information System for Tuberculosis Notification) were collected after removal of improper repeat records and record linkage. Tuberculosis incidence rates were estimated according to geographical unit, age group, sex, clinical manifestation and treatment schedule and standardized for population age group distribution based on 2000 Population Census. […]

OBJECTIVE: To describe the profile of notified tuberculosis cases and analyze the factors associated with treatment dropout. METHODS: A total of 178 cases of tuberculosis notified in the western region of Belo Horizonte (Southeastern Brazil) in 2001 and 2002 and recorded in the National System for Notifiable Diseases were described. An unmatched case-control study was conducted, with data collected by means of interviews, to compare patients who dropped out of treatment with those who achieved cure. The following variables were […]

Data was drawn from a study on the epidemiological trends of tuberculosis among children of Rio de Janeiro county, Brazil. There was an increased incidence of tuberculosis among children and epidemiological health indicators were above the national average.

A derivation of the relation Pt = I. d where: Pt = pointprevalence; I = incidence; d = average durantion of disease is presented given the disease is stable, that is, the incidence and duration remained constant over time.

OBJECTIVE: To assess the spatial pattern of tuberculosis incidence in relation to the Aids epidemic, with the aim of investigating the geographical influence on causality. METHODS: All Aids cases from State of São Paulo, notified to the Brazilian Ministry of Health between 1991 and 2001, were included. The cases were stratified by municipality, by administrative health regions, Aids transmission categories, gender and years since diagnosis. A Gaussian geostatistical model was used to construct a thematic risk map, utilizing the tuberculosis […]

The present study is an update review on the occurrence and diagnosis of rickettsial diseases in Brazil and Portugal, aiming at promoting their epidemiological surveillance in both countries. A literature review was carried out and unpublished data of laboratories and surveillance systems were presented. The results described the occurrence of rickettsial diseases and infections in Brazil and Portugal, including other new and still poorly understood rickettsial infections. Current diagnostic methods were discussed. As in many other countries, rickettsial diseases and […]

OBJECTIVE: To perform spatial analysis on dengue transmission in a medium-sized city in the interior of the State of São Paulo, Brazil, covering the period from September 1990 to August 2002. METHODS: Autochthonous cases with confirmation by laboratory tests were utilized. Population data on the city of São José do Rio Preto were obtained from the Brazilian Institute for Geography and Statistics and the municipal authorities. The cases were georeferenced according to street addresses and clustered according to the 432 […]

OBJECTIVE: To assess the association between the proportion of buildings positive for Aedes aegypti larvae measured by means of building infestation rate and dengue incidence rate. METHODS: Autochthonous dengue cases were selected and building infestation rates assessed in the coverage areas of health districts in the city of Belo Horizonte, Brazil, from October 1997 to May 2001. After grouping building infestation rates according to their distribution in quartiles, mean dengue incidence rates (for the month following the building infestation assessment) […]
