Item Aedes (Stegomyia) albopictus’ dynamics influenced by spatiotemporal characteristics in a Brazilian dengue-endemic risk city.(2016) Bezerra, Juliana Maria Trindade; Araújo, Raphaela Guedes Pereira; Melo, Fabrício Freire de; Gonçalves, Caroline Macedo; Chaves, Bárbara Aparecida; Silva, Breno de Mello; Silva, Luciana Diniz; Brandão, Silvana Tecles; Secundino, Nagila Francinete Costa; Norris, Douglas; Pimenta, Paulo Filemon PaolucciBrazil reported the majority of the dengue cases in Americas during the last two decades, where theoccurrence of human dengue cases is exclusively attributed to the Aedes (Stegomyia) aegypti (Linnaeus).Nowadays, other recognized Dengue virus (DENV) vector in Asian countries, Aedes (Stegomyia) albopictus(Skuse), has been detected in more than half of the 5565 Brazilian municipalities. Therefore, the aim of thepresent study was to investigate the presence of, and determine the Ae. albopictus’ dynamics influencedby spatiotemporal characteristics in a dengue-endemic risk city of Belo Horizonte, Minas Gerais State’scapital. Aedes albopictus were collected across four consecutive DENV transmission seasons from 2010 to2014. These mosquitoes were caught in three selected districts, which had been reported in the previousten years as having high mosquito densities and an elevated concentration of human dengue cases dur-ing epidemic seasons. All field-caught Ae. albopictus was individually processed by real-time RT-PCR, toresearch the DENV presence. The third season (p < 0.05) and the Pampulha district (p < 0.05) had the high-est proportions of field-caught Ae. albopictus, respectively. The second season had the highest proportionof DENV-infected field-caught females (p < 0.05), but there was no difference among the proportions ofDENV-infected Ae. albopictus when comparing the collection in the three districts (p = 0.98). Minimum(p = 0.004) and maximum (p < 0.0001) temperature were correlated with the field-caught Ae. albopic-tus in four different periods and districts. In the generalized linear model of Poisson, the field-caughtDENV-infected Ae. albopictus (p = 0.005), East district (p = 0.003), minimum temperature (p < 0.0001) andrelative humidity (p = 0.001) remained associated with the total number of human dengue cases. Ourstudy demonstrated that the number of field-caught DENV-infected Ae. albopictus was inversed corre-lated with the number of human dengue cases. Our study raises the possibility that the DENV circulating inmosquitoes Ae. albopictus is happening in non-epidemic periods, showing that this species may be keep-ing only the presence of the virus in nature. Further long-term studies are necessary to better understandthe role of Ae. albopictus in DENV transmission and or its vectorial competence in Belo Horizonte and inother endemic cities in Brazil and in the New World countries.Item Distinct variation in vector competence among nine field populations of Aedes aegypti from a Brazilian dengue-endemic risk city.(2014) Gonçalves, Caroline Macedo; Melo, Fabrício Freire de; Bezerra, Juliana Maria Trindade; Chaves, Bárbara Aparecida; Silva, Breno de Mello; Silva, Luciana Diniz; Pessanha, José Eduardo Marques; Arias, Jorge; Secundino, Nagila Francinete Costa; Norris, Douglas; Pimenta, Paulo Filemon PaolucciItem Spatiotemporal dynamics and risk estimates of COVID-19 epidemic in Minas Gerais State : analysis of an expanding process.(2021) Vital, Wendel Coura; Cardoso, Diogo Tavares; Ker, Fabricio Thomaz de Oliveira; Magalhães, Fernanda do Carmo; Bezerra, Juliana Maria Trindade; Viegas, Ana Maria; Morais, Maria Helena Franco; Bastos, Leonardo Soares; Reis, Ilka Afonso; Carneiro, Mariângela; Barbosa, David SoeiroCOVID-19 is an infectious disease caused by the recently discovered coronavirus SARS-Cov-2. The disease became pandemic affecting many countries globally, including Brazil. Considering the expansion process and particularities during the initial stages of the epidemic, we aimed to analyze the spatial and spatiotemporal patterns of COVID-19 occurrence and to identify priority risk areas in Minas Gerais State, Southeast Brazil. An ecological study was performed considering all data from human cases of COVID-19 confirmed from the epidemiological week (EW) 11 (March 08, 2020) to EW 26 (June 27, 2020). Crude and smoothed incidence rates were used to analyze the distribution of disease patterns based on global and local indicators of spatial association and space-time risk assessment. Positive spatial autocorrelation and spatial dependence were found. Our results suggest that the metropolitan region of the State capital Belo Horizonte (MRBH) and Vale do Rio Doce mesoregions, as major epidemic foci in the beginning of the expansion process, have had important influence on the dispersion of SARS-CoV-2 in Minas Gerais State. Triangulo Mineiro/Alto Paranaiba region presented the highest risk of infection. In addition, six statistically significant spatiotemporal clusters were identified in the State, three at high risk and three at low risk. Our findings contribute to a greater understanding of the space-time disease dynamic and discuss strategies for identification of priority areas for COVID-19 surveillance and control.
