Resumo: In order to illustrate the relationships between the biotopes (or phytogeographical zones), arbovirus vectors and vertebrate hosts (including man), and epidemiology, current knowledge on the transmission of Yellow Fever virus in West Africa is reported. A dynamic scheme has been devised to integrate the observed geographical distribution of cases and the timing of their occurrence. Two principal areas, endemicity and epidetnicity, were defined according to the presence or absence of sylvatic monkey-mosquito transmission. The intensity and potential of contacts between humans and vectors depends on the degree of man-made changes in the environment, often increasing the extension of ecotone areas where the mosquitoes are easily biting at the ground level. Prevention and/or control of arbovirus diseases require detailed eco-epidemiological studies to determine: (1) the effective role of each potential vector in each phytogeographical region; (2) the risk factors for the people living in or near areas with a sylvatic transmission cycle; (3) the priorities - vaccination and/or control - for preventing the expansion of natural foci.

Um modelo dinâmico foi desenvolvido para integrar a distribuição geográfica dos casos observados e o momento de sua ocorrência. Duas áreas principais, endemicidade e epidemicidade, foram definidas de acordo com a presença ou ausência de transmissão silvática macaco-mosquito. A intensidade e o potencial dos contatos entre homem e vetores depende do grau das alterações ambientais produzidas pelas atividades humanas, geralmente aumentando a extensão das áreas de ecótono onde os mosquitos estão ativos ao nível do solo. A prevenção e/ou controle de arboviroses requer estudos eco-epidemiológicos detalhados para que se conheça (1) o papel de cada vetor potencial em cada região fitogeográfica; (2) os fatores de risco para as pessoas vivendo nas proximidades ou nas áreas de transmissão silvestre; (3) quais são as prioridades (vacinação e/ou controle) para prevenir a expansão dos focos naturais.Reports in Public HealthCadernos de Saúde Pública1992-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/404Reports in Public Health; Vol. 8 No. 3 (1992): July/SeptemberCadernos de Saúde Pública; v. 8 n. 3 (1992): Julho/Setembro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/404/813https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/404/814Cordellier, RogerDegallier, Nicolasinfo:eu-repo/semantics/openAccess2024-03-06T15:25:51Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/404Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:00:35.982936Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
