Raiva bovina no estado de São Paulo e sua distribuição espacial entre 1992 e 2003

Abstract

RESUMODescreveu-se a influência do relevo, da precipitação, da temperatura e da sazonalidade na distribuição espacial da raiva bovina. Para a realização dessa análise, foi construído um banco geográfico de dados que possibilitou a geração de uma função kernel, com base no somatório anual dos diagnósticos de raiva laboratorialmente positivos entre 1992 e 2003, bem como a verificação da sua relação com as demais variáveis. Constatou-se que a região com relevo montanhoso, maiores índices pluviométricos e temperatura mais amena do planalto atlântico e da província costeira correspondeu às áreas com maior densidade da função, contrapondo-se à região do planalto ocidental com menores índices pluviométricos e áreas mais quentes. Não se observou, no estado, relação entre sazonalidade e raiva bovina no período estudado. A região plana da depressão periférica e o eixo de conurbação São Paulo-Campinas são óbices que dividem, respectivamente, a enfermidade entre as regiões leste-oeste e leste-sul do estado.

Em virtude de sua importância para as áreas da saúde pública, da ecologia e da economia (Mayen, 2004), tem sido estudada desde o século passado, principalmente com o objetivo de identificar áreas prioritárias para o seu controle (Kotait et al., 1998; Gomes et al., 2007

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

“…The studied time series showed no seasonality in the occurrence of rabies cases in cattle, corroborating with Gomes and Monteiro [19], who evaluated the distribution of cattle rabies in São Paulo state, and Lopes et al . [3], who studied the time series of rabies cases in Minas Gerais state.…”

“…The studied time series showed no seasonality in the occurrence of rabies cases in cattle, corroborating with Gomes and Monteiro [19], who evaluated the distribution of cattle rabies in São Paulo state, and Lopes et al [3], who studied the time series of rabies cases in Minas Gerais state. However, the lowest averages of occurrence of rabies from April to June allow the OVS to institute a specific state calendar of rabies vaccination in May, applying the booster dose to the first vaccinated animals after 30 days and annual revaccination of the entire herd, especially in municipalities where rabies has a higher incidence.…”

Diseases with neurological manifestations diagnosed in cattle in the hospital routine: a retrospective epidemiological study (2009-2019)

“…The highest numbers of outbreaks occurred in the years 2010/2011, which declined in the following years and rose again in the years 2018/2019. A similar cyclicity every five or seven years was found in the states of Pernambuco (12) , São Paulo (21) , and Mato Grosso do Sul (2) . According to Barros et al (4) , this is because there is an apparently cyclical characteristic of outbreaks of rabies in herbivores in South America, with a periodicity of 3-7 years.…”

Defining New Pathways to Manage the Ongoing Emergence of Bat Rabies in Latin America

“…D. rotundus occurs throughout tropical and subtropical Latin America, from northern Mexico to northern Argentina and Chile [11], and occupies different ecosystems including tropical rainforests, coastal deserts, xeric shrublands, and mountainous regions up to 3600 m [11]. Factors influencing bat presence and rabies risk at large spatial scales include temperature, altitude and precipitation, whereas, at local scales, livestock density, human-induced forest fragmentation, density/proximity of highways and rivers appear to be important [11,20,21]. Growth in the D. rotundus population over the last century relates to an increase in access to livestock as a food source and availability of man-made structures that could be used as roosts including mines, tunnels, wells, culverts, and abandoned houses [6,21].…”

“…This suggests that culls might require very small populations of bats to reduce rabies risk, a target that could not be practically achievable in most areas. Consistent with this idea, spillover to livestock persists or has increased in some areas with regular culling, although the specific effects of culling have not been tested and it is conceivable that increases could reflect reductions in the amount of culling [20,47]. Detailed studies directly quantifying the impacts of culling on bat behavior, demography and rabies transmission in different environmental contexts are urgently needed.…”
