Identification of risk areas for arboviruses transmitted by in northern Brazil: A One Health analysis.

Introduction: The complex and growing problem generated by the rapid expansion of unplanned urban areas includes high population density and increased infestation by vectors responsible for the transmission of several diseases. This requires interdisciplinary and intersectoral interventions due to the burden of diseases, especially those caused by arboviruses, which can present severe forms and generate significant pressure on health systems, especially in more vulnerable regions. The of this study was to analyze the spatial distribution of arboviruses transmitted by (dengue, Zika, and chikungunya) and assess their correlations with demographic, social, and environmental data from the state of Tocantins, Brazil.

Statistical analysis between 2006 and 2019 and forecast of rabies in cattle for 2020 and 2022 in Tocantins State (Brazil), by using the R Studio software.

Rabies in cattle is a viral disease with mandatory notification in Brazil, transmitted by , which causes an invariably fatal acute encephalitis. To understand the dynamics of this disease in Tocantins state, Brazil, an analysis of the time series of rabies cases in cattle between 2006 and 2019 was carried out to describe the pattern of its occurrence, aiming to subsidise the Official Veterinary Service (OVS) with relevant information to enable the improvement of control actions provided for in the guidelines of the National Program for the Control of Rabies in Herbivores (NPCRH). The statistical analyses of the time series under study were performed using the R Studio software, version 1.
