Evaluation on the effectiveness of actions for controlling infestation by rodents in Campo Limpo region, São Paulo Municipality, Brazil

Rodents are responsible for the transmission of more than 60 diseases both to human beings and to domestic animals. The increase in rodent infestation in a given area brings several health problems to the nearby population. Thus, when infestation increases, it is time to take intervention measures. Although many countries have implemented programs aimed at controlling rodent infestation, literature on studies evaluating the effectiveness of intervention measures in urban areas is scarce. Aimed at contributing to the understanding of rodents population dynamics in urban areas, the objective of this study was to evaluate the effectiveness of the control methods proposed by Programa de Vigilancia e Controle de Roedores do Municýpio de Sao Paulo (Program for Rodents Surveillance and Control in Sao Paulo Municipality), conducted on Jardim Comercial District. As a first step, a survey to assess infestation rates was conducted in 1529 dwellings located in the area studied. After that, a chemical control upon rodents was accomplished in every dwelling infested. One week and six months after completion of control measures, a new evaluation on infestation rates was carried out, in order to verify the effectiveness of the procedures taken and to estimate the re-infestation capacity. Initial infestation rate was 40.0%, and the final infestation rate, 14.4%. Therefore, the effectiveness of the control methods utilized was 63.8%. It can thus be concluded that the control methods applied were quite effective.

Dengue no município de São Paulo: uma análise por Geoprocessamento / Dengue in the city of Sao Paulo: an analysis by Geoprocessing

A dengue tornou-se um grande problema em muitos centros urbanos modernos, uma vez que tais locais fornecem os contextos propícios à ocorrência desta endemia. As características inerentes aos processos de urbanização vivenciadas pelas metrópoles brasileiras, como o município de São Paulo, criaram condições favoráveis à disseminação do vetor e à instalação de epidemias através da introdução do vírus via casos importados. A cidade de São Paulo, contudo, sempre registrara uma preponderância de casos importados sobre os autóctones até o ano de 2003, quando o município experimentou uma epidemia marcada pela transmissão local do agravo (incidência de 7,2 casos/100.000 habitantes, sendo confirmados 787 casos autóctones e 779 casos importados). A identificação dos locais que albergaram aglomerados de casos, bem como sua caracterização do ponto de vista demográfico e socioeconômico, forneceriam informações relevantes acerca do comportamento espacial dessa enfermidade, especialmente em ambientes urbanos complexos como a cidade de São Paulo. Nesse sentido, as técnicas de geoprocessamento e, em especial, o Sistema de Informação Geográfica (SIG) fornecem uma estratégia de abordagem do espaço no contexto dos estudos epidemiológicos. A estimação de densidade de Kernel, uma das ferramentas de análise espacial encerradas no SIG, permite a identificação e delimitação de aglomerados espaciais de casos, bem como de características demográficas e socioeconômicas que compõem os diferentes recortes do ambiente urbano. Os casos importados apresentaram um padrão de dispersão maior, sendo registrado na maioria dos distritos administrativos e formando um grande aglomerado espacial abrangendo distritos da região central, de melhor perfil socioeconômico, maior densidade populacional e de maior densidade de domicílios. Os autóctones demonstraram uma menor dispersão espacial, poupando vários distritos e formando quatro grandes aglomerados disjuntos espacialmente e abrangendo áreas mais peri...
